@lili-yu22 I installed Shape Variation Analyzer using Slicer 5.0.2 through the Extensions Manager on Windows and it included joblib and threadpoolctl. How did you install the extension? Through the Extensions Manager? Installing from file? Cloning from GitHub and building from source?

Please use the latest Slicer Stable Release (currently 5.0.3, in a few days 5.2.x) or the latest Slicer Preview Release (currently 5.3.x).

Hi, thank you for your reply! However, I have still the same problem:

ShapeVariationAnalyzer does not work!

That is just a warning and not an error. I issued a PR to fix these warnings in ShapeVariationAnalyzer back in June, but the developers of that extension haven’t responded to integrate the change.

Is there something with your usage of ShapeVariationAnalyzer that is not working?

Hi, I am using Slicer 5.2.2 and I have installed Shape Variation Analyzer by adding it as an extension. However, I do not see it as a module in the module list. Please help.
