Hello,  
I recently discovered the extension SlicerSPECTRecon and have successfully been able to get it working on Windows with 3D Slicer version 5.6.2.  
However, I am encountering issues when trying to run it on Ubuntu. Do you have any idea why this might be happening?

Thank you for your support and for the great work!  
Kind regards,  
Michel

I haven’t used that extension myself, but I can see in the screenshot that `torchvision` is not found. You can try the [SlicerPyTorch](https://github.com/fepegar/SlicerPyTorch/tree/e1c85cc0a62e92fa6c38223cd88c611906adb60e) extension.
