TotalSegmentator fails with error 120

It seems that your model files download was incomplete, either due to some transient network issues or the download was interrupted.

You need to erase the /home/lipteck/.totalsegmentator/ folder and start again.

This indicates that there is an issue with your CUDA installation. Currently, pytorch supports CUDA 11.6 and 11.7 on Linux, for best compatibility install one of these CUDA versions. Then check if CUDA version shown in PyTorchUtils module in Slicer matches the installed CUDA version.
