AI segmentation with lung CT analyzer error

Hi, I’ve been trying to use the Lung CT Analyzer extension with the AI segmentation ‘lung mask’, but I cannot get it to work. First, an error occurred that ‘torch was not present’, but I solved this by installing PyTorch extension in slicer (and then install pytorch via this module). However, afterwards I still get an error when I try to segment the lung.

First, when I press apply, I get a warning:

pytorch CUDA is not found on your system. The AI processing will last 3-10 minutes. Do you want to continue?

If I press OK, I will get the following error:

Failed to compute results: Command ‘[‘C:/Users/mmdeboer/AppData/Local/NA-MIC/Slicer 5.0.3/bin/…/bin\PythonSlicer.EXE’, ‘-m’, ‘pip’, ‘install’, ‘git+’]’ returned non-zero exit status 1.

What do I have to do to solve this error? Thanks in advance!

What GPU do you have in use?
Message 1 is normal if you have no GPU or a GPU that does not support CUDA. CUDA needs an Nvidia GPU.

This is strange.
Could you restart Slicer and paste


into the Python Interactor, press return, and post the result?
Thank you.
