Lung CT segmenter

I am trying to segment lung CT into lobes (Using lung mask LTRC lobes\_231). Using slicer 5.4.0.

No matter how many times I reloaded lungmask file, there still seems to be a problem with a corruption of the file.

I have Pytorch (torch and torch vision properly installed (and reinstalled) using pytorch utilities) as well as CU118.

Python Console shows the following:

Any ideas?  
Thanks very much.

Lungmask works well on our systems. That is what I get when I use the CT Chest demo dataset and 5.4.0 with lungmaskLCTRlobes:

My recommendation would be to delete everything and start from scratch again - Install 3D Slicer, Pytorch via the Pytorch extension, restart Slicer, and then install Lung CT Analyzer. Some files may be corrupted.
