Operating system: MacOS Big Sur 11.4 Slicer version: 5.6.2 Hello, I have installed Slicer, installed Pytorch version 2.2.2 via the Pytorch utils module, installed the 3d segmentator module, and restarted Slicer. When attempting to run segmentation on test CT Chest data, I get the following error. …

Failed to build opencv-python TotalSegmentator listed rt_utils in its dependency list, which is an unnecessary package (it is only needed for RTSTRUCT export, but Slicer can do that already) and it is a problematic package, because it depends on opencv-python, which is a complex, messy package th…

Thank you, however I followed your advice and am still coming up with a similar error. I updated the TotalSegmentator extension and selected force reinstall TotalSegmentator python package. Error log as below: Command '['/Applications/Slicer.app/Contents/bin/../bin/PythonSlicer', '/Applications/Sli…

Maybe opencv-python does not have wheel for this specific linux distribution. Anyway, OpenCV is messy and it is not needed, so the best is to just not install it. The TotalSegmentator extension that you download today will no longer attempt to install opencv-python, so it should be all good. To get…

[image] gsmattay: MacOS Big Sur 11.4 Apologies, the user appears to be on macOS 11 where that latest opencv-python version has a macOS 11+ whl but only on Apple Silicon. If this was an Intel mac, then it needs macOS 12+. [{EDE3F05C-9B07-4F93-8B07-008F70B7673D}]

Thank you all for your help. After updating to macOS Ventura 13.7, it worked.

I have a similar problem that I can’t solve. I can’t install the pyarrow package in Slicer, which is necessary for TotalSegmentator to work. When I try to force a reinstall, I get the following message: Failed to build pyarrow ERROR: Could not build wheels for pyarrow, which is required to install…

Normally commonly used packages don’t need to be built but binary wheels are downloaded from PyPI. Probably you had internet connectivity issues or some firewalls or proxy server interfered with the operation. I cannot tell because you did not include that part of the error message, only the last sm…
