Installing natten for PMRF...
Searching for CUDA and Torch versions for installing atten needed by PMRF...
************************************
Error: Can't find CUDA runtime version, can't install natten  PMRF will not work until natten is installed, see https://github.com/SHI-Labs/NATTEN for help in installing natten.

This should not happen because I have CUDA and torch installed and Comfy-UI already detects it.

Edit: I'm on Windows, so this is probably Windows/Natten related, not ComfyUI-PMRF.

If you are on Windows, this isn't an issue with ComfyUI-PMRF. It's an issue with Natten. In the README.md the author, 2kpr, writes about this issue.
Is it even possible to install natten on Windows?
The author created a few Windows builds that might help some people
more Windows wheels of NATTEN

You will have to build Natten from source to get it to work on your machine if you can't find a build that matches your specs.
You can install ComfyUI on Windows WSL (Linux) and this ComfyUI-PMRF plugin should install just fine because there are already many Linux Natten builds available for it to pull from automatically.
You should specify in the comments if you are running on Linux, so the ComfyUI-PMRF author can know if it's not Windows/Natten related.
