Unspecified Warning upon first call to import pyKeops #297
Description
Using the installation guide provided here, #281, I have installed Keops on a Windows box running python 3.9. However, I also get an unspecified warning when I first import any function e.g.
import pykeops
[KeOps] Warning : There were warnings or errors compiling formula :
CUDA_CUDART_LIBRARY = C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.7/lib/x64/cudart.lib
CUDA_LIBRARIES = C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.7/lib/x64/cudart_static.lib
CUDA_TOOLKIT_ROOT_DIR = C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.7
set nvrtc path = C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.7/lib/x64
pybind11_INCLUDE_DIRS = C:/Users/Adam/anaconda3/envs/pytorch/Lib/site-packages/pybind11-2.10.4-py3.9.egg/pybind11/include;C:/Users/Adam/anaconda3/envs/pytorch/include
PYTHON_LIBRARY = C:/Users/Adam/anaconda3/envs/pytorch/libs/python39.lib
OK
And on occasion
>>>test_numpy_bindings()
c:\sdks\keops\pykeops\pykeops\numpy\utils.py:112: RuntimeWarning: overflow encountered in cast
return np.empty(shape).astype(dtype)
pyKeOps with numpy bindings is working!
Despite this, if I repeat to try the import or run test_numpy_bindings() call again, they work without warning / error and pykeops.test_torch_bindings() always passes ok. Furthermore, running KeOps.py benchmark appears to give solid results.
