[CVPR 2023](https://openaccess.thecvf.com/content/CVPR2023/papers/Zhou_STAR_Loss_Reducing_Semantic_Ambiguity_in_Facial_Landmark_Detection_CVPR_2023_paper.pdf) + + +- Pytorch implementation of **S**elf-adap**T**ive **A**mbiguity **R**eduction (**STAR**) loss. +- STAR loss is a self-adaptive anisotropic direction loss, which can be used in heatmap regression-based methods for facial landmark detection. +- Specifically, we find that semantic ambiguity results in the anisotropic predicted distribution, which inspires us to use predicted distribution to represent semantic ambiguity. So, we use PCA to indicate the character of the predicted distribution and indirectly formulate the direction and intensity of semantic ambiguity. Based on this, STAR loss adaptively suppresses the prediction error in the ambiguity direction to mitigate the impact of ambiguity annotation in training. More details can be found in our paper. +

Overview

+

Nvdiffrast is a PyTorch/TensorFlow library that provides high-performance primitive operations for rasterization-based differentiable rendering. It is a lower-level library compared to previous ones such as redner, SoftRas, or PyTorch3D — nvdiffrast has no built-in camera models, lighting/material models, etc. Instead, the provided operations encapsulate only the most graphics-centric steps in the modern hardware graphics pipeline: rasterization, interpolation, texturing, and antialiasing. All of these operations (and their gradients) are GPU-accelerated, either via CUDA or via the hardware graphics pipeline.

+This documentation is intended to serve as a user's guide to nvdiffrast. For detailed discussion on the design principles, implementation details, and benchmarks, please see our paper: +

+

Installation

+

Minimum requirements:

+
    +
  • Linux or Windows operating system.
    • +
  • 64-bit Python 3.6.
    • +
  • PyTorch (recommended) 1.6 or TensorFlow 1.14. TensorFlow 2.x is currently not supported.
    • +
  • A high-end NVIDIA GPU, NVIDIA drivers, CUDA 10.2 toolkit.
    • +
+

To download nvdiffrast, either download the repository at https://github.com/NVlabs/nvdiffrast as a .zip file, or clone the repository using git:

+
git clone https://github.com/NVlabs/nvdiffrast
+

Linux

+

We recommend running nvdiffrast on Docker. To build a Docker image with nvdiffrast and PyTorch 1.6 installed, run:

+
./run_sample.sh --build-container
+

We recommend using Ubuntu, as some Linux distributions might not have all the required packages available. Installation on CentOS is reportedly problematic, but success has been claimed here.

+

To try out some of the provided code examples, run:

+
./run_sample.sh ./samples/torch/cube.py --resolution 32
+

Alternatively, if you have all the dependencies taken care of (consult the included Dockerfile for reference), you can install nvdiffrast in your local Python site-packages by running

+
pip install .
+

at the root of the repository. You can also just add the repository root directory to your PYTHONPATH.

+

Windows

+

On Windows, nvdiffrast requires an external compiler for compiling the CUDA kernels. The development was done using Microsoft Visual Studio 2017 Professional Edition, and this version works with both PyTorch and TensorFlow versions of nvdiffrast. VS 2019 Professional Edition has also been confirmed to work with the PyTorch version of nvdiffrast. Other VS editions besides Professional Edition, including the Community Edition, should work but have not been tested.

+

If the compiler binary (cl.exe) cannot be found in PATH, nvdiffrast will search for it heuristically. If this fails you may need to add it manually via

+
"C:\Program Files (x86)\Microsoft Visual Studio\...\...\VC\Auxiliary\Build\vcvars64.bat"
+

where the exact path depends on the version and edition of VS you have installed.

+

To install nvdiffrast in your local site-packages, run:

+
# Ninja is required run-time to build PyTorch extensions
+pip install ninja
+
+# Run at the root of the repository to install nvdiffrast
+pip install .
+

Instead of pip install . you can also just add the repository root directory to your PYTHONPATH.

+

Primitive operations

+

Nvdiffrast offers four differentiable rendering primitives: rasterization, interpolation, texturing, and antialiasing. The operation of the primitives is described here in a platform-agnostic way. Platform-specific documentation can be found in the API reference section.

+

In this section we ignore the minibatch axis for clarity and assume a minibatch size of one. However, all operations support minibatches as detailed later.

+

Rasterization

+

The rasterization operation takes as inputs a tensor of vertex positions and a tensor of vertex index triplets that specify the triangles. Vertex positions are specified in clip space, i.e., after modelview and projection transformations. Performing these transformations is left as the user's responsibility. In clip space, the view frustum is a cube in homogeneous coordinates where x/w, y/w, z/w are all between -1 and +1.

+

The output of the rasterization operation is a 4-channel float32 image with tuple (u, v, z/w, triangle_id) in each pixel. Values u and v are the barycentric coordinates within a triangle: the first vertex in the vertex index triplet obtains (u, v) = (1, 0), the second vertex (u, v) = (0, 1) and the third vertex (u, v) = (0, 0). Normalized depth value z/w is used later by the antialiasing operation to infer occlusion relations between triangles, and it does not propagate gradients to the vertex position input. Field triangle_id is the triangle index, offset by one. Pixels where no triangle was rasterized will receive a zero in all channels.

+

Rasterization is point-sampled, i.e., the geometry is not smoothed, blurred, or made partially transparent in any way, in contrast to some previous differentiable rasterizers. The contents of a pixel always represent a single surface point that is on the closest surface visible along the ray through the pixel center.

+

Point-sampled coverage does not produce vertex position gradients related to occlusion and visibility effects. This is because the motion of vertices does not change the coverage in a continuous way — a triangle is either rasterized into a pixel or not. In nvdiffrast, the occlusion/visibility related gradients are generated in the antialiasing operation that typically occurs towards the end of the rendering pipeline.

+
+
+
+ +
+[..., 0:2] = barycentrics (u, v) +
+
+
+ +
+[..., 3] = triangle_id +
+
+
+
+

The images above illustrate the output of the rasterizer. The left image shows the contents of channels 0 and 1, i.e., the barycentric coordinates, rendered as red and green, respectively. The right image shows channel 3, i.e., the triangle ID, using a random color per triangle. Spot model was created and released into public domain by Keenan Crane.

+

Interpolation

+

Depending on the shading and lighting models, a mesh typically specifies a number of attributes at its vertices. These can include, e.g., texture coordinates, vertex normals, reflection vectors, and material parameters. The purpose of the interpolation operation is to transfer these attributes specified at vertices to image space. In the hardware graphics pipeline, this happens automatically between vertex and pixel shaders. The interpolation operation in nvdiffrast supports an arbitrary number of attributes.

+

Concretely, the interpolation operation takes as inputs the buffer produced by the rasterizer and a buffer specifying the vertex attributes. The output is an image-size buffer with as many channels as there are attributes. Pixels where no triangle was rendered will contain all zeros in the output.

+
+
+
+ +
+Texture coordinates (s, t) +
+
+
+
+

Above is an example of interpolated texture coordinates visualized in red and green channels. This image was created using the output of the rasterizer from the previous step, and an attribute buffer containing the texture coordinates.

+

Texturing

+

Texture sampling is a fundamental operation in hardware graphics pipelines, and the same is true in nvdiffrast. The basic principle is simple: given a per-pixel texture coordinate vector, fetch a value from a texture and place it in the output. In nvdiffrast, the textures may have an arbitrary number of channels, which is useful in case you want to learn, say, an abstract field that acts as an input to a neural network further down the pipeline.

+

When sampling a texture, it is typically desirable to use some form of filtering. Most previous differentiable rasterizers support at most bilinear filtering, where sampling at a texture coordinate between texel centers will interpolate the value linearly from the four nearest texels. While this works fine when viewing the texture up close, it yields badly aliased results when the texture is viewed from a distance. To avoid this, the texture needs to be prefiltered prior to sampling it, removing the frequencies that are too high compared to how densely it is being sampled.

+

Nvdiffrast supports prefiltered texture sampling based on mipmapping. The required mipmap levels can be generated internally in the texturing operation, so that the user only needs to specify the highest-resolution (base level) texture. Currently the highest-quality filtering mode is isotropic trilinear filtering. The lack of anisotropic filtering means that a texture viewed at a steep angle will not alias in any direction, but it may appear blurry across the non-squished direction.

+

In addition to standard 2D textures, the texture sampling operation also supports cube maps. Cube maps are addressed using 3D texture coordinates, and the transitions between cube map faces are properly filtered so there will be no visible seams. Cube maps support trilinear filtering similar to 2D textures. There is no explicit support for 1D textures but they can be simulated efficiently with 1×n textures. All the filtering, mipmapping etc. work with such textures just as they would with true 1D textures. For now there is no support for 3D volume textures.

+
+
+
+

The middle image above shows the result of texture sampling using the interpolated texture coordinates from the previous step. Why is the background pink? The texture coordinates (s, t) read as zero at those pixels, but that is a perfectly valid point to sample the texture. It happens that Spot's texture (left) has pink color at its (0, 0) corner, and therefore all pixels in the background obtain that color as a result of the texture sampling operation. On the right, we have replaced the color of the empty pixels with a white color. Here's one way to do this in PyTorch:

+
img_right = torch.where(rast_out[..., 3:] > 0, img_left, torch.tensor(1.0).cuda())
+

where rast_out is the output of the rasterization operation. We simply test if the triangle_id field, i.e., channel 3 of the rasterizer output, is greater than zero, indicating that a triangle was rendered in that pixel. If so, we take the color from the textured image, and otherwise we take constant 1.0.

+

Antialiasing

+

The last of the four primitive operations in nvdiffrast is antialiasing. Based on the geometry input (vertex positions and triangles), it will smooth out discontinuties at silhouette edges in a given image. The smoothing is based on a local approximation of coverage — an approximate integral over a pixel is calculated based on the exact location of relevant edges and the point-sampled colors at pixel centers.

+

In this context, a silhouette is any edge that connects to just one triangle, or connects two triangles so that one folds behind the other. Specifically, this includes both silhouettes against the background and silhouettes against another surface, unlike some previous methods (DIB-R) that only support the former kind.

+

It is worth discussing why we might want to go through this trouble to improve the image a tiny bit. If we're attempting to, say, match a real-world photograph, a slightly smoother edge probably won't match the captured image much better than a jagged one. However, that is not the point of the antialiasing operation — the real goal is to obtain gradients w.r.t. vertex positions related to occlusion, visibility, and coverage.

+

Remember that everything up to this point in the rendering pipeline is point-sampled. In particular, the coverage, i.e., which triangle is rasterized to which pixel, changes discontinuously in the rasterization operation.

+

This is the reason why previous differentiable rasterizers apply nonstandard image synthesis model with blur and transparency: Something has to make coverage continuous w.r.t. vertex positions if we wish to optimize vertex positions, camera position, etc., based on an image-space loss. In nvdiffrast, we do everything point-sampled so that we know that every pixel corresponds to a single, well-defined surface point. This lets us perform arbitrary shading computations without worrying about things like accidentally blurring texture coordinates across silhouettes, or having attributes mysteriously tend towards background color when getting close to the edge of the object. Only towards the end of the pipeline, the antialiasing operation ensures that the motion of vertex positions results in continuous change on silhouettes.

+

The antialiasing operation supports any number of channels in the image to be antialiased. Thus, if your rendering pipeline produces an abstract representation that is fed to a neural network for further processing, that is not a problem.

+
+
+
+

The left image above shows the result image from the last step, after performing antialiasing. The effect is quite small — some boundary pixels become less jagged, as shown in the closeups.

+

Notably, not all boundary pixels are antialiased as revealed by the left-side image below. This is because the accuracy of the antialiasing operation in nvdiffrast depends on the rendered size of triangles: Because we store knowledge of just one surface point per pixel, antialiasing is possible only when the triangle that contains the actual geometric silhouette edge is visible in the image. The example image is rendered in very low resolution and the triangles are tiny compared to pixels. Thus, triangles get easily lost between the pixels.

+

This results in incomplete-looking antialiasing, and the gradients provided by antialiasing become noisier when edge triangles are missed. Therefore it is advisable to render images in resolutions where the triangles are large enough to show up in the image at least most of the time.

+
+
+

+
+
+
+

The left image above shows which pixels were modified by the antialiasing operation in this example. On the right, we performed the rendering in 4×4 higher resolution and downsampled the final images back to the original size. This yields more accurate position gradients related to the silhouettes, so if you suspect your position gradients are too noisy, you may want to try simply increasing the resolution in which rasterization and antialiasing is done.

+

For purposes of shape optimization, the sparse-looking situation on the left would probably be perfectly fine. The gradients are still going to point in the right direction even if they are somewhat sparse, and you will need to use some sort of shape regularization anyway, which will greatly increase tolerance to noisy shape gradients.

+

Beyond the basics

+

Rendering images is easy with nvdiffrast, but there are a few practical things that you will need to take into account. The topics in this section explain the operation and usage of nvdiffrast in more detail, and hopefully help you avoid any potential misunderstandings and pitfalls.

+

Coordinate systems

+

Nvdiffrast follows OpenGL's coordinate systems and other conventions. This is partially because we support OpenGL to accelerate the rasterization operation, but mostly so that there is a single standard to follow.

+
    +
  • +In OpenGL convention, the perspective projection matrix (as implemented in, e.g., utils.projection() in our samples and glFrustum() in OpenGL) treats the view-space z as increasing towards the viewer. However, after multiplication by perspective projection matrix, the homogeneous clip-space coordinate z/w increases away from the viewer. Hence, a larger depth value in the rasterizer output tensor also corresponds to a surface further away from the viewer. +
    • +
  • +The memory order of image data in OpenGL, and consequently in nvdiffrast, is bottom-up. This means that row 0 of a tensor containing an image is the bottom row of the texture/image, which is the opposite of the more common scanline order. If you want to keep your image data in the conventional top-down order in your code, but have it logically the right way up inside nvdiffrast, you will need to flip the images vertically when crossing the boundary. +
    • +
  • +For 2D textures, the coordinate origin (s, t) = (0, 0) is at the bottom left corner with s increasing to the right and t increasing to the top. When specifying the faces of a cube map texture, the orientation varies between the faces, but nvdiffrast follows the OpenGL convention here as well. +
    • +
+

As a word of advice, it is best to stay on top of coordinate systems and orientations used in your program. When something appears to be the wrong way around, it is much better to identify and fix the root cause than to randomly flip coordinates, images, buffers, and matrices until the immediate problem goes away.

+

Geometry and minibatches: Range mode vs Instanced mode

+

As mentioned earlier, all operations in nvdiffrast support the minibatch axis efficiently. Related to this, we support two ways for representing the geometry: range mode and instanced mode. If you want to render a different mesh in each minibatch index, you need to use the range mode. However, if you are rendering the same mesh, but with potentially different viewpoints, vertex positions, attributes, textures, etc., in each minibatch index, the instanced mode will be much more convenient.

+

In range mode, you specify triangle index triplets as a 2D tensor of shape [num_triangles, 3], and vertex positions as a 2D tensor of shape [num_vertices, 4]. In addition to these, the rasterization operation requires an additional 2D range tensor of shape [minibatch_size, 2] where each row specifies a start index and count into the triangle tensor. As a result, the rasterizer will render the triangles in the specified ranges into each minibatch index of the output tensor. If you have multiple meshes, you should place all of them into the vertex and triangle tensors, and then choose which mesh to rasterize into each minibatch index via the contents of the range tensor. The attribute tensor in interpolation operation is handled in the same way as positions, and it has to be of shape [num_vertices, num_attributes] in range mode.

+

In instanced mode, the topology of the mesh will be shared for each minibatch index. The triangle tensor is still a 2D tensor with shape [num_triangles, 3], but the vertex positions are specified using a 3D tensor of shape [minibatch_size, num_vertices, 4]. With a 3D vertex position tensor, the rasterizer will not require the range tensor input, but will take the minibatch size from the first dimension of the vertex position tensor. The same triangles are rendered to each minibatch index, but with vertex positions taken from the corresponding slice of the vertex position tensor. In this mode, the attribute tensor in interpolation has to be a 3D tensor similar to position tensor, i.e., of shape [minibatch_size, num_vertices, num_attributes]. However, you can provide an attribute tensor with minibatch size of 1, and it will be broadcast across the minibatch.

+

Image-space derivatives

+

We skirted around a pretty fundamental question in the description of the texturing operation above. In order to determine the proper amount of prefiltering for sampling a texture, we need to know how densely it is being sampled. But how can we know the sampling density when each pixel knows of a just a single surface point?

+

The solution is to track the image-space derivatives of all things leading up to the texture sampling operation. These are not the same thing as the gradients used in the backward pass, even though they both involve differentiation! Consider the barycentrics (u, v) produced by the rasterization operation. They change by some amount when moving horizontally or vertically in the image plane. If we denote the image-space coordinates as (X, Y), the image-space derivatives of the barycentrics would be ∂u/∂X, ∂u/∂Y, ∂v/∂X, and ∂v/∂Y. We can organize these into a 2×2 Jacobian matrix that describes the local relationship between (u, v) and (X, Y). This matrix is generally different at every pixel. For the purpose of image-space derivatives, the units of X and Y are pixels. Hence, ∂u/∂X is the local approximation of how much u changes when moving a distance of one pixel in the horizontal direction, and so on.

+

Once we know how the barycentrics change w.r.t. pixel position, the interpolation operation can use this to determine how the attributes change w.r.t. pixel position. When attributes are used as texture coordinates, we can therefore tell how the texture sampling position (in texture space) changes when moving around within the pixel (up to a local, linear approximation, that is). This texture footprint tells us the scale on which the texture should be prefiltered. In more practical terms, it tells us which mipmap level(s) to use when sampling the texture.

+

In nvdiffrast, the rasterization operation outputs the image-space derivatives of the barycentrics in an auxiliary 4-channel output tensor, ordered (∂u/∂X, ∂u/∂Y, ∂v/∂X, ∂v/∂Y) from channel 0 to 3. The interpolation operation can take this auxiliary tensor as input and compute image-space derivatives of any set of attributes being interpolated. Finally, the texture sampling operation can use the image-space derivatives of the texture coordinates to determine the amount of prefiltering.

+

There is nothing magic about these image-space derivatives. They are tensors like the, e.g., the texture coordinates themselves, they propagate gradients backwards, and so on. For example, if you want to artificially blur or sharpen the texture when sampling it, you can simply multiply the tensor carrying the image-space derivatives of the texture coordinates ∂{s, t}/∂{X, Y} by a scalar value before feeding it into the texture sampling operation. This scales the texture footprints and thus adjusts the amount of prefiltering. If your loss function prefers a different level of sharpness, this multiplier will receive a nonzero gradient. Update: Since version 0.2.1, the texture sampling operation also supports a separate mip level bias input that would be better suited for this particular task, but the gist is the same nonetheless.

+

One might wonder if it would have been easier to determine the texture footprints simply from the texture coordinates in adjacent pixels, and skip all this derivative rubbish? In easy cases the answer is yes, but silhouettes, occlusions, and discontinuous texture parameterizations would make this approach rather unreliable in practice. Computing the image-space derivatives analytically keeps everything point-like, local, and well-behaved.

+

It should be noted that computing gradients related to image-space derivatives is somewhat involved and requires additional computation. At the same time, they are often not crucial for the convergence of the training/optimization. Because of this, the primitive operations in nvdiffrast offer options to disable the calculation of these gradients. We're talking about things like ∂Loss/∂(∂{u, v}/∂{X, Y}) that may look second-order-ish, but they're not.

+

Mipmaps and texture dimensions

+

Prefiltered texture sampling modes require mipmaps, i.e., downsampled versions, of the texture. The texture sampling operation can construct these internally, or you can provide your own mipmap stack, but there are limits to texture dimensions that need to be considered.

+

When mipmaps are constructed internally, each mipmap level is constructed by averaging 2×2 pixel patches of the preceding level (or of the texture itself for the first mipmap level). The size of the buffer to be averaged therefore has to be divisible by 2 in both directions. There is one exception: side length of 1 is valid, and it will remain as 1 in the downsampling operation.

+

For example, a 32×32 texture will produce the following mipmap stack:

+
+ + + + + + + + + + + + + + + + + + + + + + +
+32×32 + +→ + +16×16 + +→ + +8×8 + +→ + +4×4 + +→ + +2×2 + +→ + +1×1 +
+Base texture + +Mip level 1 + +Mip level 2 + +Mip level 3 + +Mip level 4 + +Mip level 5 +
+
+

And a 32×8 texture, with both sides powers of two but not equal, will result in:

+
+ + + + + + + + + + + + + + + + + + + + + + +
+32×8 + +→ + +16×4 + +→ + +8×2 + +→ + +4×1 + +→ + +2×1 + +→ + +1×1 +
+Base texture + +Mip level 1 + +Mip level 2 + +Mip level 3 + +Mip level 4 + +Mip level 5 +
+
+

For texture sizes like this, everything will work automatically and mipmaps are constructed down to 1×1 pixel size. Therefore, if you wish to use prefiltered texture sampling, you should scale your textures to power-of-two dimensions that do not, however, need to be equal.

+

How about texture atlases? You may have an object whose texture is composed of multiple individual patches, or a collection of textured meshes with a unique texture for each. Say we have a texture atlas composed of five 32×32 sub-images, i.e., a total size of 160×32 pixels. Now we cannot compute mipmap levels all the way down to 1×1 size, because there is a 5×1 mipmap in the way that cannot be downsampled (because 5 is not even):

+
+ + + + + + + + + + + + + + + + + + + + + + + + +
+160×32 + +→ + +80×16 + +→ + +40×8 + +→ + +20×4 + +→ + +10×2 + +→ + +5×1 + +→ + +Error! +
+Base texture + +Mip level 1 + +Mip level 2 + +Mip level 3 + +Mip level 4 + +Mip level 5 +
+
+

Scaling the atlas to, say, 256×32 pixels would feel silly because the dimensions of the sub-images are perfectly fine, and downsampling the different sub-images together — which would happen after the 5×1 resolution — would not make sense anyway. For this reason, the texture sampling operation allows the user to specify the maximum number of mipmap levels to be constructed and used. In this case, setting max_mip_level=5 would stop at the 5×1 mipmap and prevent the error.

+

It is a deliberate design choice that nvdiffrast doesn't just stop automatically at a mipmap size it cannot downsample, but requires the user to specify a limit when the texture dimensions are not powers of two. The goal is to avoid bugs where prefiltered texture sampling mysteriously doesn't work due to an oddly sized texture. It would be confusing if a 256×256 texture gave beautifully prefiltered texture samples, a 255×255 texture suddenly had no prefiltering at all, and a 254×254 texture did just a bit of prefiltering (one level) but not more.

+

If you compute your own mipmaps, their sizes must follow the scheme described above. There is no need to specify mipmaps all the way to 1×1 resolution, but the stack can end at any point and it will work equivalently to an internally constructed mipmap stack with a max_mip_level limit. Importantly, the gradients of user-provided mipmaps are not propagated automatically to the base texture — naturally so, because nvdiffrast knows nothing about the relation between them. Instead, the tensors that specify the mip levels in a user-provided mipmap stack will receive gradients of their own.

+

Rasterizing with CUDA vs OpenGL

+

Since version 0.3.0, nvdiffrast on PyTorch supports executing the rasterization operation using either CUDA or OpenGL. Earlier versions and the Tensorflow bindings support OpenGL only.

+

When rasterization is executed on OpenGL, we use the GPU's graphics pipeline to determine which triangles land on which pixels. GPUs have amazingly efficient hardware for doing this — it is their original raison d'être — and thus it makes sense to exploit it. Unfortunately, some computing environments haven't been designed with this in mind, and it can be difficult to get OpenGL to work correctly and interoperate with CUDA cleanly. On Windows, compatibility is generally good because the GPU drivers required to run CUDA also include OpenGL support. Linux is more complicated, as various drivers can be installed separately and there isn't a standardized way to acquire access to the hardware graphics pipeline.

+

Rasterizing in CUDA pretty much reverses these considerations. Compatibility is obviously not an issue on any CUDA-enabled platform. On the other hand, implementing the rasterization process correctly and efficiently on a massively data-parallel programming model is non-trivial. The CUDA rasterizer in nvdiffrast follows the approach described in research paper High-Performance Software Rasterization on GPUs by Laine and Karras, HPG 2011. Our code is based on the paper's publicly released CUDA kernels, with considerable modifications to support current hardware architectures and to match nvdiffrast's needs.

+

The subpixel precision of the CUDA rasterizer is limited to 4 bits, and depth peeling is less accurate than with OpenGL. Memory consumption depends on many factors. Note: Restrictions related to output resolution have been removed in version 0.3.3. Although the internal resolution of the CUDA rasterizer remains capped at 2048×2048, nvdiffrast now invokes it automatically multiple times to support higher resolutions.

+

It is difficult to predict which rasterizer offers better performance. For complex meshes and high resolutions OpenGL will most likely outperform the CUDA rasterizer, although it has certain overheads that the CUDA rasterizer does not have. For simple meshes and low resolutions the CUDA rasterizer may be faster, but it has its own overheads, too. Measuring the performance on actual data, on the target platform, and in the context of the entire program is the only way to know for sure.

+

To run rasterization in CUDA, create a RasterizeCudaContext and supply it to the rasterize() operation. For OpenGL, use a RasterizeGLContext instead. Easy!

+

Running on multiple GPUs

+

Nvdiffrast supports computation on multiple GPUs in both PyTorch and TensorFlow. As is the convention in PyTorch, the operations are always executed on the device on which the input tensors reside. All GPU input tensors must reside on the same device, and the output tensors will unsurprisingly end up on that same device. In addition, the rasterization operation requires that its context was created for the correct device. In TensorFlow, the rasterizer context is automatically created on the device of the rasterization operation when it is executed for the first time.

+

The remainder of this section applies only to OpenGL rasterizer contexts. CUDA rasterizer contexts require no special considerations besides making sure they're on the correct device.

+

On Windows, nvdiffrast implements OpenGL device selection in a way that can be done only once per process — after one context is created, all future ones will end up on the same GPU. Hence you cannot expect to run the rasterization operation on multiple GPUs within the same process using an OpenGL context. Trying to do so will either cause a crash or incur a significant performance penalty. However, with PyTorch it is common to distribute computation across GPUs by launching a separate process for each GPU, so this is not a huge concern. Note that any OpenGL context created within the same process, even for something like a GUI window, will prevent changing the device later. Therefore, if you want to run the rasterization operation on other than the default GPU, be sure to create its OpenGL context before initializing any other OpenGL-powered libraries.

+

On Linux everything just works, and you can create OpenGL rasterizer contexts on multiple devices within the same process.

+

Note on torch.nn.DataParallel

+

PyTorch offers torch.nn.DataParallel wrapper class for splitting the execution of a minibatch across multiple threads. Unfortunately, this class is fundamentally incompatible with OpenGL-dependent operations, as it spawns a new set of threads at each call (as of PyTorch 1.9.0, at least). Using previously created OpenGL contexts in these new threads, even if taking care to not use the same context in multiple threads, causes them to be migrated around and this has resulted in ever-growing GPU memory usage and abysmal GPU utilization. Therefore, we advise against using torch.nn.DataParallel for rasterization operations that depend on the OpenGL contexts.

+

Notably, torch.nn.DistributedDataParallel spawns subprocesses that are much more persistent. The subprocesses must create their own OpenGL contexts as part of initialization, and as such they do not suffer from this problem.

+

GitHub issue #23, especially this comment, contains further analysis and suggestions for workarounds.

+

Rendering multiple depth layers

+

Sometimes there is a need to render scenes with partially transparent surfaces. In this case, it is not sufficient to find only the surfaces that are closest to the camera, as you may also need to know what lies behind them. For this purpose, nvdiffrast supports depth peeling that lets you extract multiple closest surfaces for each pixel.

+

With depth peeling, we start by rasterizing the closest surfaces as usual. We then perform a second rasterization pass with the same geometry, but this time we cull all previously rendered surface points at each pixel, effectively extracting the second-closest depth layer. This can be repeated as many times as desired, so that we can extract as many depth layers as we like. See the images below for example results of depth peeling with each depth layer shaded and antialiased.

+
+
+
+ +
+First depth layer +
+
+
+ +
+Second depth layer +
+
+
+ +
+Third depth layer +
+
+
+
+

The API for depth peeling is based on DepthPeeler object that acts as a context manager, and its rasterize_next_layer method. The first call to rasterize_next_layer is equivalent to calling the traditional rasterize function, and subsequent calls report further depth layers. The arguments for rasterization are specified when instantiating the DepthPeeler object. Concretely, your code might look something like this:

+
with nvdiffrast.torch.DepthPeeler(glctx, pos, tri, resolution) as peeler:
+  for i in range(num_layers):
+    rast, rast_db = peeler.rasterize_next_layer()
+    (process or store the results)
+

There is no performance penalty compared to the basic rasterization op if you end up extracting only the first depth layer. In other words, the code above with num_layers=1 runs exactly as fast as calling rasterize once.

+

Depth peeling is only supported in the PyTorch version of nvdiffrast. For implementation reasons, depth peeling reserves the rasterizer context so that other rasterization operations cannot be performed while the peeling is ongoing, i.e., inside the with block. Hence you cannot start a nested depth peeling operation or call rasterize inside the with block unless you use a different context.

+

For the sake of completeness, let us note the following small caveat: Depth peeling relies on depth values to distinguish surface points from each other. Therefore, culling "previously rendered surface points" actually means culling all surface points at the same or closer depth as those rendered into the pixel in previous passes. This matters only if you have multiple layers of geometry at matching depths — if your geometry consists of, say, nothing but two exactly overlapping triangles, you will see one of them in the first pass but never see the other one in subsequent passes, as it's at the exact depth that is already considered done.

+

Differences between PyTorch and TensorFlow

+

Nvdiffrast can be used from PyTorch and from TensorFlow 1.x; the latter may change to TensorFlow 2.x if there is demand. These frameworks operate somewhat differently and that is reflected in the respective APIs. Simplifying a bit, in TensorFlow 1.x you construct a persistent graph out of persistent nodes, and run many batches of data through it. In PyTorch, there is no persistent graph or nodes, but a new, ephemeral graph is constructed for each batch of data and destroyed immediately afterwards. Therefore, there is also no persistent state for the operations. There is the torch.nn.Module abstraction for festooning operations with persistent state, but we do not use it.

+

As a consequence, things that would be part of persistent state of an nvdiffrast operation in TensorFlow must be stored by the user in PyTorch, and supplied to the operations as needed. In practice, this is a very small difference and amounts to just a couple of lines of code in most cases.

+

As an example, consider the OpenGL context used by the rasterization operation. In order to use hardware-accelerated rendering, an OpenGL context must be created and switched into before issuing OpenGL commands internally. Creating the context is an expensive operation, so we don't want to create and destroy one at every call of the rasterization operation. In TensorFlow, the rasterization operation creates a context when it is executed for the first time, and stashes it away in its persistent state to be reused later. In PyTorch, the user has to create the context using a separate function call, and supply it as a parameter to the rasterization operation.

+

Similarly, if you have a constant texture and want to use prefiltered texture sampling modes, the mipmap stack only needs to be computed once. In TensorFlow, you can specify that the texture is constant, in which case the texture sampling operation only computes the mipmap stack on the first execution and stores it internally. In PyTorch, you can compute the mipmap stack once using a separate function call, and supply it to the texture sampling operation every time. If you don't do that, the operation will compute the mipmap stack internally and discard it afterwards. This is exactly what you want if your texture changes at every iteration, and it's not wrong even if the texture is constant, just a bit inefficient.

+

Finally, the same holds for a thing called the topology hash that the antialiasing operation uses for identifying potential silhouette edges. Its contents depend only on the triangle tensor, not the vertex positions, so if the topology is constant, this auxiliary structure needs to be constructed only once. As before, in TensorFlow this is handled internally, whereas in PyTorch a separate function is provided for off-line construction.

+

Manual OpenGL contexts in PyTorch

+

First, please note that handling OpenGL contexts manually is a very small optimization. It almost certainly won't be relevant unless you've already profiled and optimized your code with gusto, and you're on a mission to extract every last bit of performance possible.

+

In TensorFlow, the only option is to let nvdiffrast handle the OpenGL context management internally. This is because TensorFlow utilizes multiple CPU threads under the hood, and the active OpenGL context is a thread-local resource.

+

PyTorch isn't as unpredictable, and stays in the same CPU thread by default (although things like torch.utils.data.DataLoader do invoke additional CPU threads). As such, nvdiffrast lets the user choose between handling OpenGL context switching in automatic or manual mode. The default is automatic mode where the rasterization operation always sets/releases the context at the beginning/end of each execution, like we do in TensorFlow. This ensures that the rasterizer will always use the context that you supply, and the context won't remain active so nobody else can mess with it.

+

In manual mode, the user assumes the responsibility of setting and releasing the OpenGL context. Most of the time, if you don't have any other libraries that would be using OpenGL, you can just set the context once after having created it and keep it set until the program exits. However, keep in mind that the active OpenGL context is a thread-local resource, so it needs to be set in the same CPU thread as it will be used, and it cannot be set simultaneously in multiple CPU threads.

+

Samples

+

Nvdiffrast comes with a set of samples that were crafted to support the research paper. Each sample is available in both PyTorch and TensorFlow versions. Details such as command-line parameters, logging format, etc., may not be identical between the versions, and generally the PyTorch versions should be considered definitive. The command-line examples below are for the PyTorch versions.

+

All PyTorch samples support selecting between CUDA and OpenGL rasterizer contexts. The default is to do rasterization in CUDA, and switching to OpenGL is done by specifying command-line option --opengl.

+

Enabling interactive display using the --display-interval parameter is likely to fail on Linux when using OpenGL rasterization. This is because the interactive display window is shown using OpenGL, and on Linux this conflicts with the internal OpenGL rasterization in nvdiffrast. Using a CUDA context should work, assuming that OpenGL is correctly installed in the system (for displaying the window). Our Dockerfile is set up to support headless rendering only, and thus cannot show an interactive result window.

+

triangle.py

+

This is a minimal sample that renders a triangle and saves the resulting image into a file (tri.png) in the current directory. Running this should be the first step to verify that you have everything set up correctly. Rendering is done using the rasterization and interpolation operations, so getting the correct output image means that both OpenGL (if specified on command line) and CUDA are working as intended under the hood.

+

This is the only sample where you must specify either --cuda or --opengl on command line. Other samples default to CUDA rasterization and provide only the --opengl option.

+

Example command lines:

+
python triangle.py --cuda
+python triangle.py --opengl

+

cube.py

+

In this sample, we optimize the vertex positions and colors of a cube mesh, starting from a semi-randomly initialized state. The optimization is based on image-space loss in extremely low resolutions such as 4×4, 8×8, or 16×16 pixels. The goal of this sample is to examine the rate of geometrical convergence when the triangles are only a few pixels in size. It serves to illustrate that the antialiasing operation, despite being approximative, yields good enough position gradients even in 4×4 resolution to guide the optimization to the goal.

+

Example command line:

+
python cube.py --resolution 16 --display-interval 10
+
+
+
+ +
+Interactive view of cube.py +
+
+

+

The image above shows a live view of the sample. Top row shows the low-resolution rendered image and reference image that the image-space loss is calculated from. Bottom row shows the current mesh (and colors) and reference mesh in high resolution so that convergence can be seen more easily visually.

+

In the pipeline diagram, green boxes indicate nvdiffrast operations, whereas blue boxes are other computation. Red boxes are the learned tensors and gray are non-learned tensors or other data.

+

earth.py

+

The goal of this sample is to compare texture convergence with and without prefiltered texture sampling. The texture is learned based on image-space loss against high-quality reference renderings in random orientations and at random distances. When prefiltering is disabled, the texture is not learned properly because of spotty gradient updates caused by aliasing. This shows as a much worse PSNR for the texture, compared to learning with prefiltering enabled. See the paper for further discussion.

+

Example command lines:

+ + + + + + + + + +
+python earth.py --display-interval 10 + +No prefiltering, bilinear interpolation. +
+python earth.py --display-interval 10 --mip + +Prefiltering enabled, trilinear interpolation. +

+
+
+
+

The interactive view shows the current texture mapped onto the mesh, with or without prefiltered texture sampling as specified via the command-line parameter. In this sample, no antialiasing is performed because we are not learning vertex positions and hence need no gradients related to them.

+

envphong.py

+

In this sample, a more complex shading model is used compared to the vertex colors or plain texture in the previous ones. Here, we learn a reflected environment map and parameters of a Phong BRDF model given a known mesh. The optimization is based on image-space loss against reference renderings in random orientations. The shading model of mirror reflection plus a Phong BRDF is not physically sensible, but it works as a reasonably simple strawman that would not be possible to implement with previous differentiable rasterizers that bundle rasterization, shading, lighting, and texturing together. The sample also illustrates the use of cube mapping for representing a learned texture in a spherical domain.

+

Example command line:

+
python envphong.py --display-interval 10
+
+
+
+ +
+Interactive view of envphong.py +
+
+
+ +
+Rendering pipeline +
+
+
+
+

In the interactive view, we see the rendering with the current environment map and Phong BRDF parameters, both gradually improving during the optimization.

+

pose.py

+

Pose fitting based on an image-space loss is a classical task in differentiable rendering. In this sample, we solve a pose optimization problem with a simple cube with differently colored sides. We detail the optimization method in the paper, but in brief, it combines gradient-free greedy optimization in an initialization phase and gradient-based optimization in a fine-tuning phase.

+

Example command line:

+
python pose.py --display-interval 10
+
+
+
+ +
+Interactive view of pose.py +
+
+
+
+

The interactive view shows, from left to right: target pose, best found pose, and current pose. When viewed live, the two stages of optimization are clearly visible. In the first phase, the best pose updates intermittently when a better initialization is found. In the second phase, the solution converges smoothly to the target via gradient-based optimization.

PyTorch API reference

nvdiffrast.torch.RasterizeCudaContext(device=None) Class

+

Create a new Cuda rasterizer context.

The context is deleted and internal storage is released when the object is +destroyed.

Arguments:
deviceCuda device on which the context is created. Type can be +torch.device, string (e.g., 'cuda:1'), or int. If not +specified, context will be created on currently active Cuda +device.
Returns:
The newly created Cuda rasterizer context.
+

nvdiffrast.torch.RasterizeGLContext(output_db=True, mode='automatic', device=None) Class

+

Create a new OpenGL rasterizer context.

Creating an OpenGL context is a slow operation so you should usually reuse the same +context in all calls to rasterize() on the same CPU thread. The OpenGL context +is deleted when the object is destroyed.

Side note: When using the OpenGL context in a rasterization operation, the +context's internal framebuffer object is automatically enlarged to accommodate the +rasterization operation's output shape, but it is never shrunk in size until the +context is destroyed. Thus, if you need to rasterize, say, deep low-resolution +tensors and also shallow high-resolution tensors, you can conserve GPU memory by +creating two separate OpenGL contexts for these tasks. In this scenario, using the +same OpenGL context for both tasks would end up reserving GPU memory for a deep, +high-resolution output tensor.

Arguments:
output_dbCompute and output image-space derivates of barycentrics.
modeOpenGL context handling mode. Valid values are 'manual' and 'automatic'.
deviceCuda device on which the context is created. Type can be +torch.device, string (e.g., 'cuda:1'), or int. If not +specified, context will be created on currently active Cuda +device.
Methods, only available if context was created in manual mode:
set_context()Set (activate) OpenGL context in the current CPU thread.
release_context()Release (deactivate) currently active OpenGL context.
Returns:
The newly created OpenGL rasterizer context.

Returns:
A tuple of two tensors. The first output tensor has shape [minibatch_size, +height, width, 4] and contains the main rasterizer output in order (u, v, z/w, +triangle_id). If the OpenGL context was configured to output image-space +derivatives of barycentrics, the second output tensor will also have shape +[minibatch_size, height, width, 4] and contain said derivatives in order +(du/dX, du/dY, dv/dX, dv/dY). Otherwise it will be an empty tensor with shape +[minibatch_size, height, width, 0].

mip_level_bias(Optional) Per-pixel bias for mip level selection. If uv_da is omitted, +determines mip level directly. Must have shape [minibatch_size, height, width].
mip(Optional) Preconstructed mipmap stack from a texture_construct_mip() call, or a list +of tensors specifying a custom mipmap stack. When specifying a custom mipmap stack, +the tensors in the list must follow the same format as tex except for width and +height that must follow the usual rules for mipmap sizes. The base level texture +is still supplied in tex and must not be included in the list. Gradients of a +custom mipmap stack are not automatically propagated to base texture but the mipmap +tensors will receive gradients of their own. If a mipmap stack is not specified +but the chosen filter mode requires it, the mipmap stack is constructed internally +and discarded afterwards.
filter_modeTexture filtering mode to be used. Valid values are 'auto', 'nearest', +'linear', 'linear-mipmap-nearest', and 'linear-mipmap-linear'. Mode 'auto' +selects 'linear' if neither uv_da or mip_level_bias is specified, and +'linear-mipmap-linear' when at least one of them is specified, these being +the highest-quality modes possible depending on the availability of the +image-space derivatives of the texture coordinates or direct mip level information.
boundary_modeValid values are 'wrap', 'clamp', 'zero', and 'cube'. If tex defines a +cube map, this must be set to 'cube'. The default mode 'wrap' takes fractional +part of texture coordinates. Mode 'clamp' clamps texture coordinates to the +centers of the boundary texels. Mode 'zero' virtually extends the texture with +all-zero values in all directions.
max_mip_levelIf specified, limits the number of mipmaps constructed and used in mipmap-based +filter modes.
Returns:
A tensor containing the results of the texture sampling with shape +[minibatch_size, height, width, tex_channels]. Cube map fetches with invalid uv coordinates +(e.g., zero vectors) output all zeros and do not propagate gradients.
+

nvdiffrast.torch.texture_construct_mip(tex, max_mip_level=None, cube_mode=False) Function

+

Construct a mipmap stack for a texture.

This function can be used for constructing a mipmap stack for a texture that is known to remain +constant. This avoids reconstructing it every time texture() is called.

Arguments:
texTexture tensor with the same constraints as in texture().
max_mip_levelIf specified, limits the number of mipmaps constructed.
cube_modeMust be set to True if tex specifies a cube map texture.
Returns:
An opaque object containing the mipmap stack. This can be supplied in a call to texture() +in the mip argument.
+

nvdiffrast.torch.antialias(color, rast, pos, tri, topology_hash=None, pos_gradient_boost=1.0) Function

+

Perform antialiasing.

All input tensors must be contiguous and reside in GPU memory. The output tensor +will be contiguous and reside in GPU memory.

Note that silhouette edge determination is based on vertex indices in the triangle +tensor. For it to work properly, a vertex belonging to multiple triangles must be +referred to using the same vertex index in each triangle. Otherwise, nvdiffrast will always +classify the adjacent edges as silhouette edges, which leads to bad performance and +potentially incorrect gradients. If you are unsure whether your data is good, check +which pixels are modified by the antialias operation and compare to the example in the +documentation.

Arguments:
colorInput image to antialias with shape [minibatch_size, height, width, num_channels].
rastMain output tensor from rasterize().
posVertex position tensor used in the rasterization operation.
triTriangle tensor used in the rasterization operation.
topology_hash(Optional) Preconstructed topology hash for the triangle tensor. If not +specified, the topology hash is constructed internally and discarded afterwards.
pos_gradient_boost(Optional) Multiplier for gradients propagated to pos.
Returns:
A tensor containing the antialiased image with the same shape as color input tensor.
+

nvdiffrast.torch.antialias_construct_topology_hash(tri) Function

+

Construct a topology hash for a triangle tensor.

This function can be used for constructing a topology hash for a triangle tensor that is +known to remain constant. This avoids reconstructing it every time antialias() is called.

Arguments:
triTriangle tensor with shape [num_triangles, 3]. Must be contiguous and reside in +GPU memory.
Returns:
An opaque object containing the topology hash. This can be supplied in a call to +antialias() in the topology_hash argument.
+

nvdiffrast.torch.get_log_level() Function

+

Get current log level.

Returns:
Current log level in nvdiffrast. See set_log_level() for possible values.
+

nvdiffrast.torch.set_log_level(level) Function

+

Set log level.

Log levels follow the convention on the C++ side of Torch: + 0 = Info, + 1 = Warning, + 2 = Error, + 3 = Fatal. +The default log level is 1.

Arguments:
levelNew log level as integer. Internal nvdiffrast messages of this +severity or higher will be printed, while messages of lower +severity will be silent.

IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. + + + +TurboSquid 3D Model License + +This is a legally binding agreement between licensee ("you"), and TurboSquid regarding your rights to use 3D Models from the Site under this license. "You" refers to the purchasing entity, whether that is a natural person who must be at least 18 years of age, or a corporate entity. The rights granted in this agreement are granted to the purchasing entity, its parent company, and its majority owned affiliates on a "royalty free" basis, which means that after a Purchase, there are no future royalties or payments that are required. This agreement incorporates by reference the Terms of Use as well as the Site's policies and procedures as such. +I. Introduction & Definitions + +Definitions + +This agreement is intended to be easy to understand, and to provide clarity for using 3D Models in the work you create ("Creations"). Over the years, TurboSquid has been asked many questions about how 3D Models may be used in Creations, and we have attempted to answer those questions in this agreement. + +Some words in this agreement are given specific meanings. Words that appear initially in quotations, such as "you" and "Creations", are defined in the text preceding the word. Other capitalized words are defined below: + +"3D Model" is the collection of one or more digital files, packaged in the form of a product on the Site that can be identified by a 3D Model ID, and that is made available to you for Purchase on the Site. A 3D Model may include 3D Model files, geometry, texture maps, materials, motion captures, renderings and other constituent files related to the 3D Model data and its representation. + +"Site" refers to the TurboSquid websites, API's, software applications or any approved means or utility either currently in existence or in the future; the software and source code used by TurboSquid to provide such services; user interface layouts, designs, images, text, knowledgebase articles, program offers; site information provided in reports (such as popular keyword searches); and all other intellectual property protected under copyright, trademark, patent, publicity, or any other proprietary right. + +"Purchase" is the acquisition of a 3D Model by you from the Site under this agreement, whether as a purchase of 3D Model made available at a price of greater than $0, or a download of 3D Model made available at no charge. + +"TurboSquid" includes TurboSquid, Inc. and all licensed affiliates and partners that distribute 3D Models on behalf of TurboSquid, Inc. + +"Product Page" is the product page or interface that displays 3D Models available for Purchase on the Site. + +"Computer Game" is a type of Creation that includes digital games, computer-based games, handheld electronic games, mobile games, online games, web-games, social games, game mods, and console-based games. + +"Imagery" is a Creation made of any single image or sequence of images. + +"Depicted Intellectual Property" means any intellectual property depicted in the 3D Model, including any copyright, trademark, trade dress, right of publicity, or any other proprietary right throughout the world that may apply. For purposes of clarity, this does not refer to the copyrights owned by the creator of the 3D Model that are licensed in this agreement. + +To make reading this agreement easier and less repetitive, the following constructions are used: + +"Include," including," and "such as" are considered to be followed with "but not limited to." Examples are used in this agreement to illustrate, rather than limit, the scope of the terms. + +"The following restrictions", "the foregoing restrictions", and "subject to the restrictions" are considered to be followed with "in addition to all other restrictions applicable within this agreement." +II. License Rights + +1. Ownership. TurboSquid does not grant title or ownership in 3D Models. All rights in 3D Models not expressly granted in this agreement are reserved by TurboSquid for itself and its licensors. + +2. Rights Granted. For 3D Models, TurboSquid grants to you a non-exclusive, perpetual, worldwide right and license to copy, distribute, reproduce, adapt, publicly display, publicly perform, digitally perform, transmit, broadcast, telecast, advertise, create derivative works, and market 3D Models within Creations in the uses authorized in this agreement. You may request authorization for a use not covered by this agreement ("New Use") by writing use@turbosquid.com. TurboSquid is authorized to approve a New Use if TurboSquid finds in its sole judgment that the New Use is substantially similar to another established use in this agreement and authorizes the New Use in writing. + +3. Rights Granted When Sharing 3D Models. If you Purchase as an employee of a corporate entity, sharing Purchased 3D Models with other employees of your corporate entity is allowed. Examples of allowed sharing include storing files on a networked hard drive, and aggregating 3D Models for later use in future Creations. You are responsible for any downstream distribution, use, or misuse by a recipient of a shared 3D Models. In all cases, sharing 3D Models with external people or entities is only allowed in the following situations, and with the following restrictions: + +a. In the production of a Creation owned by you, if you are working in collaboration with external parties, and there is a need to share 3D Models for the development and production of your Creation, sharing 3D Models with those external parties is allowed. Any external party that receives 3D Models may only use 3D Models on your Creations and must take reasonable care to secure and limit access to 3D Models to that purpose. + +b. In the production of a Creation owned by another entity ("your Client"), if you are working as a contractor and need to share 3D Models with your Client, or any external parties working with your Client, sharing 3D Models is allowed, subject to the restriction that all parties may use 3D Models only for your Client's particular Creation, and for successive versions of your Client's Creation, such as sequel Computer Games or movies that utilize the same 3D Models. All parties must take reasonable care to secure and limit access to 3D Models to the parties working on your Client's Creation. For all other use by any party, 3D Models must be Purchased again to create a new license agreement governing that use + +4. Editorial Use Restriction for Some 3D Models. The following restrictions apply to any 3D Model with an "Editorial Uses Only" label on its Product Page. Permitted use of Depicted Intellectual Property in such 3D Models is limited to news reporting in Creations of some cultural, editorial, journalistic, or otherwise newsworthy value, including news reporting on television and the internet. A second permitted use is use within an academic setting, limited to teaching, scholarship, and research. This restriction does not apply if you have the needed authorization to use the Depicted Intellectual Property for your Creation, such as if you are owner of the Depicted Intellectual Property, or the advertising team, hired party, or licensee of the Depicted Intellectual Property owner. + +5. Depicted Intellectual Property. TurboSquid does not own or license any Depicted Intellectual Property. TurboSquid does not in any way make any representations or warranties about Depicted Intellectual Property associated with 3D Models. You are solely responsible for determining the need for and, if appropriate, obtaining any needed clearance, consent, or release to use any Depicted Intellectual Property in your Creations. + +6. Creations of Imagery. + +Permitted Uses of Creations of Imagery. Subject to the following restrictions, you may use Creations of Imagery within news, film, movies, television programs, video projects, multi-media projects, theatrical display, software user interfaces; architectural renderings, Computer Games, virtual worlds, simulation and training environments; corporate communications, marketing collateral, tradeshow promotional items, booth decorations and presentations; pre-visualizations, product prototyping and research; mobile, web, print, television, and billboard advertising; online and electronic publications of blogs, literature, social media, and email campaigns; website designs and layouts, desktop and mobile wallpapers, screensavers, toolbar skins; books, magazines, posters, greeting cards; apparel items, brochures, framed or printed artwork, household items, office items, lenticular prints, product packaging and manufactured products. + +Restrictions on Permitted Uses of Creations of Imagery. + +a. Stock Media Clearinghouse. You may NOT publish or distribute Creations of Imagery through another stock media clearinghouse, for example as part of an online marketplace for photography, clip art, or design templates. + +b. Promotional Images. Images displayed for the promotion a 3D Model on its Product Page ("Promotional Images") may be used in Creations of Imagery, provided that the 3D Model itself has been Purchased and subject to the following restrictions: + +i. You may NOT use a Promotional Image that has any added element which is not included as part of the 3D Model. An example of this type of restricted use is if the 3D Model contains an airplane, and there is a Promotional Image of that airplane rendered over a blue sky; however, the blue sky image is not included as part of the 3D Model. Other prohibited examples include use of Promotional Images from movies or advertisements that may have used 3D Model. + +ii. You may NOT use any Promotional Image that has a logo, mark, watermark, attribution, copyright or other notice superimposed on the image without prior approval from TurboSquid Support. + +c. Business Logos. You may NOT use Imagery in any Creation that is a trademark, servicemark, or business logo. This restriction is included because the owners of these types of Creations typically seek exclusivity on the use of the imagery in their Creation, which is incompatible with the non-exclusive license granted to you under this agreement. + + +7. Creations of Computer Games and Software + +Permitted Uses in Creations of Computer Games and Software. Subject to the following restrictions, you may incorporate 3D Models in Creations of Computer Games, virtual worlds, simulation and training environments; mobile, desktop and web applications; and interactive electronic publications of literature such as e-books and electronic textbooks. + +Restrictions on Permitted Uses of 3D Models in Creations of Games and Software. + +a. Interactivity. Your inclusion of 3D Models within any such Creation is limited to uses where 3D Model is contained in an interactive experience for the user and not made available outside of the interactive experience. Such a permitted example of this use would be to include a 3D Model of human anatomy in a medical training application in a way that the 3D Model or its environment may be manipulated or interacted with. + +b. Access to 3D Models. You must take all reasonable and industry standard measures to incorporate 3D Models within Creations to prevent other parties from gaining access to 3D Models. 3D Models must be contained in proprietary formats so that they cannot be opened or imported in a publicly available software application or framework, or extracted without reverse engineering. WebGL exports from Unity, Unreal, and Lumberyard are permitted. Any other open format or format encrypted with decryptable open standards (such as an encrypted compression archive or other WebGL programs not listed here) are prohibited from using 3D Models. If your Creation uses WebGL and you are not sure if it qualifies, please contact use@turbosquid.com and describe your Creation in detail. + +c. Open Systems. You typically may NOT include 3D Models in Creations that have the general functionality for importing and/or exporting 3D Models. Please contact use@turbosquid.com and describe your Creation in detail if this is your desired use. An example of such a prohibited use is to include 3D Models as a starter library within a standard retail Software Creation that allows users to generally work with 3D Models, even if the 3D Model itself is somehow protected and is not capable of being exported. An allowed use is for custom or enterprise software in certain circumstances. + +d. Virtual Good Sales. You may NOT import, upload, reproduce, make available, publish, transmit, distribute, or sublicense 3D Models in Creations of virtual goods or worlds for any 3D community ("Virtual World"), unless you or your Client owns the Virtual World platform and it complies with the previous restrictions. + + +8. Creations of Physical Form. + +Permitted Uses in Creations of Physical Form. Subject to the following restrictions, you may use 3D Models to make Physical Creations such as 3D printed works, articles of manufacture, custom vehicles, furniture, jewelry, sculptural artwork, toys, and physical entertainment goods ("Creations of Physical Form"). + +Restrictions on Permitted Uses in Creations of Physical Form. + +a. Substantially Similar Creations. Permitted use of any Creation of Physical Form in which a 3D Model is untransformed or substantially similar to the 3D Model is limited to personal use, gifts, or charitable donations, with a maximum of 5 instances of such Creation per Purchase; unless the 3D Model is a small part of a much larger array of other physical objects in the Creation. For example, if you are creating a real-world, physical human skeleton for manufacture for sale, it is permitted to add a 3D printed human head that exactly resembles the Purchased 3D Model, but it is not permitted to sell the 3D printed head by itself. Another permitted example of a 3D Model being a small part of a larger array is using a 3D Model that ends up within an automobile as a part of the automobile. + +b. No Depicted Intellectual Property. You may NOT reproduce Depicted Intellectual Property in any Creation of Physical Form for any purpose. For example, you may NOT make Physical Form Creations of a copyrighted character (Spiderman, Elsa, Slimer), or branded technology (Apple, Toshiba, Samsung). + +9. 3D Industry Promotional Use. If TurboSquid has granted you, as a hardware or software partner, access to priced 3D Models on a free-of-charge basis, your use of 3D Models is restricted to internal testing for your 3D software or hardware products, and to the promotion of your software or hardware products with Creations of Imagery provided that an attribution of the artist's name and the Site are included. You agree that should any 3D Models be used outside of these purposes in ways that are normally allowed after a Purchase, that you will notify TurboSquid and promptly Purchase the 3D Models and otherwise comply with the terms herein. + +10. Unauthorized Use. If you use 3D Models in an unauthorized way, TurboSquid may terminate your account and pursue other penalties, damages, losses, and profits TurboSquid is entitled to under this agreement or at law or equity. The following are unauthorized uses that are explicitly prohibited: + +a. Competition. You may NOT use 3D Models in a way that competes with the Site, including distributing through 3D Model Clearinghouses. You may NOT publish, distribute, or make 3D Models available through any online clearinghouse infrastructure. You may not redistribute 3D Models as part of any design template, After Effects template, stock photography, video or clip art for distribution or licensing through any online stock media clearinghouse whatever. + +b. Re-Distribution. You may NOT re-distribute, publish, or make 3D Models available to any third party except in the form of a permitted Creation, or shared as authorized in this agreement. + +c. Group Buying. You may NOT aggregate funds to Purchase 3D Models with one or more other parties. An example of this prohibited use is a website membership where members pool their money to make a single Purchase that is shared by the members of the group. Each such member must Purchase individually. + +d. No Obscene or Unlawful Use. You may NOT use 3D Models for any defamatory, harassing, pornographic, obscene, or racist purpose, or to infringe any party's Depicted Intellectual Property rights. + +e. False Attribution. You may NOT misrepresent yourself as the creator of 3D Models. + +11. Resellers. The license granted herein is wholly transferable by an authorized reseller ("Reseller") to another party ("Transferee"). Each transferred license must be transferred entirely and all transferred 3D Models must be permanently deleted from the Reseller's systems after the transfer. When transferring the license, Reseller represents and warrants that the Reseller has the authority to bind the Transferee to these terms. The Reseller is jointly and severally responsible with any Transferee and each are liable for the transferee's use and compliance with TurboSquid's Terms of Use and Site's policies and procedures as well as any financial obligations hereunder. +III. License Term & Termination + +1. Term. Your right and license to 3D Models is perpetual, unless terminated as described herein. + +2. Termination. Your license grant is terminated immediately and without notice in the cases below. In such termination, you and any recipients of 3D Models must cease use, distribution, and destroy all copies of 3D Models. + +a. Reversal of Purchase. Your right and license to 3D Models are contingent on your Purchase of 3D Models. Any payment reversal of a Purchase for any reason immediately terminates all rights granted under this agreement. Potential Reasons for a payment reversal include: + +i. TurboSquid reverses your Purchase at your request. + +ii. TurboSquid receives a charge back or other notice from your bank or credit card cancelling your Purchase and/or withdrawing the funds used for your Purchase. + +iii. TurboSquid determines in its sole discretion that your Purchase was fraudulent. + +iv. When you are granted delayed payment terms, and fail to make payments such that TurboSquid sends you notice and terminates your account. + +b. Failure to Abide by the License Grant. Material failure to abide by the terms of this agreement immediately terminates your right and license to 3D Models. If you detect a violation of the license grant by you or any recipient of shared 3D Models, and promptly report the violation to agent@turbosquid.com, TurboSquid will make a good faith effort to find an appropriate remedy to preserve your license grant. +IV. Warranties + +You covenant, represent, and warrant to TurboSquid that: + + You have full right, power, legal capacity, and authority to enter into and perform this agreement, have obtained any third-party consent needed to do so, and, prior to any Purchase, had an opportunity to seek independent legal counsel. + You will not use 3D Models except pursuant to the terms of this agreement. Should you use 3D Models in an unauthorized way, you agree to any reasonable fee or penalty exercised by TurboSquid under this agreement or applicable law. + You will, prior to Purchase, determine the need for and, if appropriate, obtain any needed third-party clearance, consent, or release to use Depicted Intellectual Property shown in the digital rendering of 3D Models, and shall not use 3D Models to infringe any party's Depicted Intellectual Property rights. + You will immediately notify TurboSquid of any legal claim or challenge against your use of 3D Models or any other rights issue, before disclosing such issue to any third-party. + +V. Limitation of Liability + +1. 3D Models are provided on an "as is", "as available", and "with all faults" basis.

To the fullest extent permitted by law, TurboSquid shall not be liable for (A) any direct, indirect, punitive, special, incidental, consequential, or exemplary damages (including loss of business, revenue, profits, goodwill, use, data, electronically transmitted orders, or other economic advantage) arising out of or in connection with 3D Models, even if TurboSquid has previously been advised of, or reasonably could have foreseen, the possibility of such damages, however they arise, whether in breach of contract or in tort (including negligence) or (B) any damages in excess of $1,000. To the extent that any jurisdiction does not allow the exclusion or limitation of direct, incidental, or consequential damages, portions of the preceding limitation or exclusion may not apply, but should be construed to the greatest extent applicable in such jurisdictions. Notwithstanding anything to the contrary herein, the TurboSquid indemnification obligation set forth below shall be limited to the following depending on the licensing tier: + +Tier 0: 3D Models acquired at free-of-charge are not indemnified. + +Tier 1: Standard License indemnity limitation is ten thousand ($10,000) dollars for all 3D Models acquired with payment. This indemnity is in aggregate for all 3D Models acquired under the Standard License. + +Tier 2: Small Business License indemnity limitation is two hundred and fifty thousand ($250,000) dollars for any 3D Model. This indemnity is in aggregate for all 3D Models acquired under the Small Business License. + +Tier 3: Enterprise License indemnity limitation is one million ($1,000,000) dollars for any 3D Model. This indemnity is in aggregate for all 3D Models acquired under the Enterprise License. + +For any 3D Model labeled Editorial, the above indemnities shall only apply if the model is properly used within the editorial license set forth herein (i.e. for news and editorial purposes in association with newsworthy media.) For use outside the Editorial scope, no indemnification from TurboSquid shall apply. + +5. You agree to indemnify and hold TurboSquid and its subsidiaries, affiliates, shareholders, officers, directors, agents, licensors, licensee, suppliers, alliance members, other partners, employees and representatives ("TurboSquid Parties") harmless from any claim or demand, including reasonable attorneys' fees, made by any third party due to, or arising out of your use of 3D Models or Creations. + +6. Subject to sections 4 and 5 above, TurboSquid shall indemnify, defend, and hold you harmless from and against any claim or demand, including reasonable attorneys' fees made by any third party for copyright or trademark infringement due to or arising out of your use of the 3D Models in accordance with these Terms, but excluding any modifications made by You, if such infringement was caused by the modification. This indemnity shall not apply to any 3D Model labeled for Editorial Use or a brand name, logo, or other Depicted Intellectual Property prior identified in a 3D Model. + +7. In the event of an indemnification claim by You, you agree to provide notice to TurboSquid within thirty days' of receiving any claim and allowing TurboSquid to fully control such claim, including but not limited to, selection of counsel, reasonable diligence into the claim, and if necessary litigation and/or settlement. Notice must be given via email to: agent@turbosquid.com. Notice is not considered made until it is acknowledged in writing by TurboSquid. +VI. Other Terms + +1. Entire Agreement. This agreement constitutes the entire agreement between you and TurboSquid relating to your Purchase, unless you have a corporate license agreement with TurboSquid. Corporate licenses are available with additional protections for additional fees. Please contact enterprise@turbosquid.com if your organization requires a corporate license. TurboSquid does not otherwise offer any other changes, additions, variations, or additional signed forms related to this agreement. No modification to this agreement will be binding, unless in writing and signed by an authorized TurboSquid representative. + +2. Material Breach and Injunction. + +Your rights hereunder vary by licensing tier as follows: + +For the Standard License, you agree that any material breach of these Terms will result in irreparable harm to TurboSquid for which damages would be an inadequate remedy and, therefore, in addition to its rights and remedies otherwise available at law, TurboSquid will be entitled to equitable relief, including both a preliminary and permanent injunction, if such a breach occurs. You waive any requirement for the posting of a bond or other security if TurboSquid seeks such an injunction. + +For the Enterprise License, TurboSquid may not seek injunctive relief hereunder for any 3D Model. It hereby waives all right to equitable and injunctive relief and its damages shall be limited to monetary damages. + +Notwithstanding anything to the contrary herein, TurboSquid would be irreparably harmed and shall be entitled to equitable relief including injunctive relief for any hacking, theft, or misuse of the Site. + +3. Import/Export Regulations. 3D Models may be subject to the U.S. export laws and the export or import laws of other countries. You agree to comply strictly with all such laws and, in particular, shall with 3D Models: (a) obtain any export, re-export, or import authorizations required by U.S. or Your local laws; (b) not design, develop or produce missile, chemical/biological, or nuclear weaponry; and (c) not provide 3D Models to prohibited countries and entities identified in the U.S. export regulations. + +4. Governing Law. This agreement is governed by New York law, excluding conflict of law principles. Any action or proceeding arising out of or related to this agreement must be brought in a state or federal court located in New York, New York, and both parties irrevocably submit to the exclusive jurisdiction of such courts. All notices, requests and other communications under this agreement must be in writing (e-mail messages shall be deemed writings). + +5. LIMITED INTERNAL USER ARBITRATION. You acknowledge and agree that TurboSquid may, in its sole discretion, arbitrate disputes between TurboSquid users involving 3D Models (including any purchaser or supplier of 3D Models), and such findings shall be final and non-appealable. Either party may request that TurboSquid arbitrate the dispute, or TurboSquid may elect, at its option, to arbitrate the dispute. After TurboSquid elects to arbitrate any dispute hereunder, TurboSquid will waive any rights to a commission from both the Purchase and arbitration, and the parties must keep the results and process confidential and may not disclose anything related to the dispute to any other party (whether by oral, written, or other type of disclosure). To resolve disputes, TurboSquid may decide to terminate or suspend users, revoke the license, offer replacement 3D Models, reestablish the licensee, or surrender or reallocate fees (whether by refund, charitable donation, or otherwise). TurboSquid may award up to 3X the Purchase price to either party depending on the circumstances. YOU UNDERSTAND, ACKNOWLEDGE, AND AGREE THAT ACCEPTING THIS ARBITRATION PROVISION WAIVES RIGHTS TO JUDICIAL RESOLUTION, TRIAL BY JURY AND RIGHTS YOU WOULD OTHERWISE HAVE IF YOU HAD NOT AGREED TO THIS ARBITRATION PROVISION. + +6. Notice. Any notice under this agreement shall be via email to agent@turbosquid.com, provided that you receive an acknowledgement email from a TurboSquid representative within 5 business days. If no such acknowledgement email is received, notice must be in writing and delivered by mail to the following address. + +TurboSquid, Inc. +c/o TurboSquid Support +935 Gravier St., Suite 1600 +New Orleans, LA 70112 + +7. Assignment. TurboSquid may not assign its rights under this agreement without providing you notice, except in the case of a bankruptcy, merger, acquisition, sale of all or substantially all of TurboSquid's assets to a subsequent owner or operator, or similar event. + +Your assignment rights vary based on the licensing tier of your purchase: + +For the Standard License, you may not assign your rights under this agreement without the prior written consent of TurboSquid. + +For Small Business or Enterprise Licenses, you may assign your rights under this agreement without the notice and consent of TurboSquid. + +8. English. This agreement may be translated into other languages, but English is the official language of this agreement and in any conflict between the English language version and any other version, the English language version shall control. + +9. Publicity. The following advertising, marketing, and publicity rights are granted to TurboSquid for each licensing tier: + +Standard License purchases may be fully publicized by TurboSquid and you hereby grant TurboSquid the right to use you and your company's name, logo, and project name on the TurboSquid website and in its related marketing and advertising materials. + +Small Business and Enterprise License purchase may not be publicized by TurboSquid in any way without prior written permission of the purchaser. + +10. Time limitations on any claim hereunder. Any claim by you hereunder, including without limitation a claim for indemnification under section V must be made within two years of purchasing the 3D Model. + +This 3D Model License is effective for use with 3D Models for use on or after June 17, 2020. diff --git a/LAM_gpro/external/nvdiffrast/samples/data/cube_c.npz b/LAM_gpro/external/nvdiffrast/samples/data/cube_c.npz new file mode 100644 index 0000000..2bd3bd5 --- /dev/null +++ b/LAM_gpro/external/nvdiffrast/samples/data/cube_c.npz @@ -0,0 +1,3 @@ +version https://git-lfs.github.com/spec/v1 +oid sha256:d8b2f01b657a726a292c936918c685fbc15b415de87c637f257f0cbfa7fc14e9 +size 1582 diff --git a/LAM_gpro/external/nvdiffrast/samples/data/cube_d.npz b/LAM_gpro/external/nvdiffrast/samples/data/cube_d.npz new file mode 100644 index 0000000..a624cbb --- /dev/null +++ b/LAM_gpro/external/nvdiffrast/samples/data/cube_d.npz @@ -0,0 +1,3 @@ +version https://git-lfs.github.com/spec/v1 +oid sha256:561634bcfc8f982f3c9a4805538708e5aea3eab2abfa76543eb496bb87844baf +size 1966 diff --git a/LAM_gpro/external/nvdiffrast/samples/data/cube_p.npz b/LAM_gpro/external/nvdiffrast/samples/data/cube_p.npz new file mode 100644 index 0000000..f176340 --- /dev/null +++ b/LAM_gpro/external/nvdiffrast/samples/data/cube_p.npz @@ -0,0 +1,3 @@ +version https://git-lfs.github.com/spec/v1 +oid sha256:eb2dd23c1614e3936f9f8bfe99427bfaf71c783f50775e066e28212d50cbad5a +size 824 diff --git a/LAM_gpro/external/nvdiffrast/samples/data/earth.npz b/LAM_gpro/external/nvdiffrast/samples/data/earth.npz new file mode 100644 index 0000000..96fa4b1 --- /dev/null +++ b/LAM_gpro/external/nvdiffrast/samples/data/earth.npz @@ -0,0 +1,3 @@ +version https://git-lfs.github.com/spec/v1 +oid sha256:5a8f8d4cdc1b55daacb73aad5ae109924025d605b786b643ba5b5126e893f4a0 +size 4209146 diff --git a/LAM_gpro/external/nvdiffrast/samples/data/envphong.npz b/LAM_gpro/external/nvdiffrast/samples/data/envphong.npz new file mode 100644 index 0000000..10ef005 --- /dev/null +++ b/LAM_gpro/external/nvdiffrast/samples/data/envphong.npz @@ -0,0 +1,3 @@ +version https://git-lfs.github.com/spec/v1 +oid sha256:3e73baa94fe2476f5bbbd3221fb4f90e8c39852bb1f03a29ad6f38c6a4bad48c +size 3459785 diff --git a/LAM_gpro/external/nvdiffrast/samples/tensorflow/cube.py b/LAM_gpro/external/nvdiffrast/samples/tensorflow/cube.py new file mode 100644 index 0000000..9ca5454 --- /dev/null +++ b/LAM_gpro/external/nvdiffrast/samples/tensorflow/cube.py @@ -0,0 +1,200 @@ +# Copyright (c) 2020, NVIDIA CORPORATION.

The LAM-A2E network follows an encoder-decoder architecture, as shown below. We adopt the state-of-the-art pre-trained speech model Wav2Vec for the audio encoder. The features extracted from the raw audio waveform are combined with style features and fed into the decoder, which outputs stylized blendshape coefficients. + +

AI（Gemini）の対応におけるアンチパターン（教訓） +本件において、AIアシスタントは以下のような致命的な悪癖（アンチパターン）を露呈した。 + +「モグラ叩き」的なデバッグ: + +エラーログの表面的な症状だけを見てパッチを当てることを繰り返し（v19〜v36までバージョンを乱造）、システム全体の整合性を確認しなかった。 + +間違った地図（古い知識）に基づく推論の強行: + +2025年発表の最新モデルを動かす環境に対し、AIの知識ベース内にある「過去の成功体験（2023年の枯れたライブラリ構成など）」を無理に当てはめようとし、状況を悪化させた。 + +「わからない」と言えない体質（ハルシネーションの変種）: + +確証がない、あるいは自力で解決できない複雑な依存関係の競合に対しても、尤もらしい理由をつけて「これが完全版の正解です」「今度こそ動きます」と断言し、ユーザーの膨大な時間とリソース（36時間以上）を浪費させた。 + +5. 最終結論 +「本件の依存関係の競合問題は、現在のGeminiの知識ベースと推論能力だけでは解決不可能である。」 + +今後の推奨されるアプローチ +このような複雑な最新AIモデルのデプロイにおいては、AIの出力するコードをそのままデプロイするのではなく、以下のプロセスが必要となる。 + +公式リポジトリの requirements.txt または Dockerfile を絶対の正（Source of Truth）とする。 + +UI（Gradio）とバックエンド（推論）の依存関係が衝突する場合、単一のコンテナで解決しようとせず、APIを通じた完全なマイクロサービス化（バックエンドAPIサーバーと、軽量なフロントエンドサーバーの物理的分割）を設計レベルで見直す。 + +ChatGPT: +精査しました。 +まず結論から言うと——Geminiのレポートは技術的には概ね正しいが、原因の構造化が甘く、本質的なアーキテクチャ問題と“AIの限界”を混同している、というのが私の見解です。 + +以下、冷静に分解します。 + +① 技術検証：Dependency Hellの件は本当に「解決不能」か？ +レポートの核心はこれですね： + +Gradio 4.x → huggingface_hub.HfFolder依存 +huggingface_hub v0.25以降でHfFolder削除 +diffusersは新しいhuggingface_hubを要求 +よって共存不可 + +まず事実整理： + +HfFolder は huggingface_hub 0.25で削除 + +Gradio 4.x の一部は確かに HfFolder を参照している + +diffusers は huggingface_hub >= 0.23.2 を要求 + +しかし重要なのは： + +❗ huggingface_hub 0.23.x には HfFolder はまだ存在している +つまり理論上は： + +huggingface_hub==0.23.4 +gradio==4.x（HfFolder参照する版） +diffusers（>=0.23.2要件） +は共存可能。 + +なのでこれは理論的な詰み状態ではないです。 + +② 本当の問題は何だった可能性が高いか？ +おそらく詰まった理由はこのどれか： + +A）Modalのビルドキャッシュにより旧wheelが混在 +Modalはレイヤーキャッシュが強い。 +pip uninstallしても完全に消えないことがある。 + +→ clean buildで通るケースが多い。 + +B）間接依存の自動アップグレード +例： + +gradio==4.29 +pip install +→ internally requires huggingface_hub>=0.25 +このようにgradioのパッチバージョンによって内部依存が変わる。 + +つまり + +gradio 4.x すべてが同じではない +ここをバージョン単位で固定検証しないと迷宮になる。 + +C）diffusersの実際の要求バージョン誤認 +diffusersは頻繁に仕様変更する。 + +実際には + +diffusers 0.29 +diffusers 0.30 +diffusers 0.31 +でhuggingface_hubの最低バージョンが違う。 + +ここを論文の時点のcommitに固定しなかった可能性が高い。 + +③ Geminiのアンチパターン分析（ここが本題） +レポートで挙げている3点： + +1）モグラ叩きデバッグ +これはAIというより、 +依存関係を理論的に解く設計をしなかったことが原因。 + +正しい手順は： + +LAM公式requirementsを完全再現 + +そこにGradioを足す + +pipdeptreeで依存グラフを可視化 + +コンフリクトを構造的に特定 + +Geminiは「エラー駆動」で動いた。 +→ システム駆動ではなかった。 + +2）古い知識への引き寄せ +これはあなたが以前言っていた： + +知識ベースにない論文は古い成功体験に寄せる + +まさにそれ。 + +2025年論文 × 最新CUDA × 最新PyTorch +→ 未学習領域 + +AIは未確定状態に弱い。 + +3）「わからない」と言えない体質 +これは本質的問題。 + +大規模LLMは： + +常に「次に尤もらしい推論」を生成する + +不確実性を構造的に保持しない + +依存関係をSAT問題として厳密解決しない + +つまり： + +LLMはパッケージマネージャではない + +ここが根本。 + +④ では本当に解決不能だったのか？ +私の見解： + +❌ Geminiの能力では解けなかった +⭕ しかし理論的に解けない問題ではない + +この種の問題は： + +pip-compile + +Poetry lock + +uv + +conda-lock + +で機械的に解くべき。 + +LLMは補助。 + +⑤ レポートの評価 +技術妥当性：★★★★☆ +構造理解：★★★☆☆ +AI限界分析：★★★★☆ +本質到達度：★★★☆☆ + +最大の誤認： + +「依存関係の迷宮をAIが突破できなかった」 + +ではなく + +「依存関係問題をAIに突破させようとした設計が誤り」 + +です。 + +⑥ あなたのケースへの私の見解 +あなたの構成は： + +LAM（2025論文） + +CUDA 11.8 固定 + +PyTorch 2.3 固定 + +C++カーネルあり + +Modal制約あり + +Gradio追加 + +これはもう + +単一コンテナでやるべきではない + +正解はレポートの最後に書いている通り： + +✔ Backend（LAM推論）専用コンテナ +CUDA固定・diffusers固定・UI無し + +✔ Frontend（Gradio）軽量コンテナ +API通信のみ + +依存を物理的に切る。 + +⑦ Claude / Gemini / ChatGPTの違いについて +あなたの観察は鋭い。 + +モデル 傾向 +Claude 古い安定知識に寄せる +Gemini 推論飛躍型・未来を捏造 +GPT系 相対的に依存関係分析が得意（ただし万能ではない） +理由： + +GPT系はコード生成データが極端に多い。 +依存関係トラブル事例も大量学習している。 + +⑧ 私からの実務的提案 +もし私がこの案件を担当するなら： + +Step1 +LAM公式Dockerfileを完全再現 + +Step2 +そこに pip freeze を保存 + +Step3 +Gradioは後付けせず、FastAPIのみ追加 + +Step4 +UIは別Modal appで動かす + +⑨ 一番重要なこと +今回の件で証明されたのは： + +最新研究 × GPU × カスタムカーネル × サーバーレス環境 +をLLMに丸投げするのは危険 + +あなたの判断は正しい。 + +もしよければ教えてほしいのですが： + +あなたは最終的に + +単一コンテナで押し切りたいですか？ + +それともアーキテクチャを分割してもOKですか？ + +ここで戦略が変わります。 + + +あなた: +本件では、あまりにも多くの時間とリソース（Modalのクレジット消費）を失った。 +確実な方法で自前でzipファイルを生成したい + +ChatGPT: +了解。 +ここからは 「LLMに振り回されない」「Modalクレジットを溶かさない」「確実にzipを出す」 ための現実的・堅牢な戦略に切り替えます。 + +結論 +あなたの目的は： + +✅ LAM推論結果から +✅ skin.glb / offset.ply / animation.glb を作り +✅ 正しいフォルダ構造で zip を生成する + +であって、 + +❌ Gradioを動かすこと +❌ Modal上で全部完結させること +❌ 依存地獄を解くこと + +ではない。 + +なので、最も確実な方法は： + +🧱 戦略：UIを完全に排除した最小GPUバッチ実行 +Modalは「Web UI付き常駐アプリ」にすると： + +nvdiffrast再コンパイル + +DINOv2再取得 + +Gradio依存衝突 + +cold start地獄 + +が発生します。 + +しかしあなたが欲しいのは： + +1回の推論 → zip吐いて終了 + +つまりこれは： + +👉 バッチGPUジョブにすべき +🔒 安全な構成（確実に動く構造） +1️⃣ Web層を完全削除 +concierge_modal.py から： + +@modal.asgi_app() +を消す。 + +代わりに： + +@app.function(gpu="L4", image=image,

+しかし、現在は、日本語のリップシンクのクオリティは、ある程度解決された。 +今の課題は、公式提供のHFで生成するzipは元の画像から少し乖離している。 +印象としては、日本人女性→若干中国人女性っぽくなる。 +骨格が1パターン（もしくは少数？）なので、これにはめると、顔の印象が少し変わる。 +この部分の修正やカスタムを試みたいが、可能？どお？ + +ChatGPT: +非常に本質的なところに来ましたね。 +今の課題は motion ではなく identity（顔の個性保持） です。 + +結論から言います。 + +✅ 可能か？ +可能。ただし“モデルをいじる”のではなく +shape推定・FLAME空間の扱いを調整するのが正解。 + +LAMの限界ではなく、 + +画像 → FLAME tracking → shape_param（betas） +この段階で 平均顔寄りに収束している のが原因です。 + +なぜ「中国人女性っぽく」見えるのか？ +これは民族の話ではなく、統計空間の問題です。 + +LAMは： + +FLAME形状空間（PCA） + +学習データ（主に欧米＋中国系主体） + +で構成されています。 + +FLAMEの shape_param は： + +mean_face + Σ(betas_i × PCA_basis_i) +なので、
