Hello,

The Lung CT Analyzer just wraps code around existent (great) AI tools like “lungmask” by Johannes Hofmanninger and “TotalSegmentator” by Jakob Wasserthal / “TotalSegmenator extension” by @lassoan.

“lungmask” works perfectly fine on two of my test systems as well as on an AWS EC2 cloud instance. All are equipped with Nvidia GPUs and low (6 GB) to moderate/high (24 GB) dedicated video RAM.
Could you provide some details of your system?

  • Operating system
  • 3D Slicer version
  • Lung CT Analyzer version
  • Type and model of GPU
  • dedicated video RAM

Thank you.

  • Operating system：win11
  • 3D Slicer version：5.22
  • Lung CT Analyzer version：Latest version
    RAM:24GB
    My computer hardware is for the use of AI,Because I have used it smoothly before,But I reinstalled Python on my computer, and then he got the above error and couldn’t use AI，I don’t know why it’s getting an error and how I can fix it？

You will probably just need to uninstall 3D Slicer and completely remove the 3D Slicer installation folder, then reinstall 3D Slicer as well as the Lung CT Analyzer extension and all dependencies. Somehow your Slicer Python seems to have been messed up.
