Hello Slicer Support!

I have been trying to run TotalSegmentator, but it has been failing. The Slicer Error message that I have been receiving states, “… returned non-zero exit status 1.”

```auto

I would uninstall and reinstall TotalSegmentator with the latest Python version. What is the RAM/CPU parameters on your device? That could also be a reason. Try TotalSegmentator with the modules test data first to see if this works…

Thank you, I have tried 2 different versions of 3D Slicer and Python, I think they re conflicting each other
