Hi everyone,

I’m trying to use the TotalSegmentator extension in 3D Slicer, but I get an error when I try to compute the segmentation.

The error message is:

ModuleNotFoundError: No module named 'skimage.morphology'

It seems quite similar to this issue, except in my case the missing module is skimage.morphology instead of acvl_utils.

Here are my system details:

Windows 11 Home
Slicer version: 5.9.0

Any ideas on how to fix this? Should I manually install scikit-image somewhere?

Thanks in advance for your help!
