Dear all,

I was plugin the TotalSegmentor extension. But got error.

**Failed to compute results.**

**Command ‘[‘C:/Users/Akmal/AppData/Local/NA-MIC/Slicer 5.2.1/bin/…/bin\PythonSlicer.EXE’, ‘-m’, ‘light\_the\_torch’, ‘install’, ‘torch’]’ returned non-zero exit status 1.**

Thanks for reporting, it is due to a regression that I introduced a few days ago when I improved GPU detection. Update PyTorch extension tomorrow in the extensions manager and it should work well. Let me know if you run into any further issues.
