ProPainter Vapoursynth filter

[Selur]

I get the filter working with CPU, but not with the GPU.
Also, I get a noticeable color shift, which does not come from some tv vs pc luma scale issue or a small matrix mix up.

Haven't found a way to get the GPU support working.
I got the same problem:

NotImplementedError: Could not run 'torchvision::deform_conv2d' with arguments from the 'CUDA' backend. This could be because the operator doesn't exist for this backend, or was omitted during the selective/custom build process (if using custom build). If you are a Facebook employee using PyTorch on mobile, please visit https://fburl.com/ptmfixes for possible resolutions.
