Same problem: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,after I put a point in trachea and press apply button,I get a confirmation like:“PyTorch will be downloaded and installed using light-the-torch (ltt install torch torchvision). The process might take some minutes.”
If I press OK, I will get the following error:Failed to compute results: Command ‘[‘D:/Slicer 5.8.1/bin/…/bin\PythonSlicer.EXE’, ‘-m’, ‘pip’, ‘install’, ‘light-the-torch>=0.5’]’ returned non-zero exit status 1.
How can I solve this problem?Thanks in advance!
