It would be good to have this in the extension repo issues: [https://github.com/fepegar/SlicerPyTorch](https://github.com/fepegar/SlicerPyTorch)

We have troubles from time to time with PyTorch, but I don’t think anyone has a magic formula to keep up with all the changes.

Can you try the pytorch local install instructions with Slicer’s python? (`PythonSlicer -m pip`)
