SlicerRadiomics Extension Not Showing Up on macOS 15.5 (Slicer 5.9.0 Preview)

Hi,

I’m trying to install and use the SlicerRadiomics extension on my Mac, but I haven’t been able to get it to show up, despite following all the instructions.

System Info:

  • macOS version: 15.5 (Sequoia)
  • Slicer version: 5.9.0-2025-05-25 r33658 (Preview build)
  • Slicer install location: Application moved to /Applications as required

What I Tried:

  1. Opened the Extension Manager and searched for “Radiomics” — nothing appeared.
  2. Verified I’m using the Preview, not Stable.
  3. Downloaded the zipped folders from GitHub: SlicerRadiomics and SlicerRadiomicsCLI
  4. Tried manually adding the module path under the Modules > Add Modules option, but it still doesn’t show up.
  5. Tried the link to download the compiled extension:
    https://slicer-packages.kitware.com/catalog/All/33658/macosx — but it’s not working.

Questions:

  • Is the SlicerRadiomics extension still unavailable for macOS?
  • Is there a manual installation method that works currently?
  • If not, what’s the best workaround? (e.g., using PyRadiomics in Python after segmentation in Slicer?)

I’d really appreciate any help, especially if anyone has gotten this to work on a Mac recently.

Thanks so much!

@hjmjohnson I see you have recently pushed a lot of maintenance related work to the pyradiomics project. Do you intend to also update the SlicerRadiomics extension to use the latest? Currently SlicerRadiomics specifies an old tag of pyradiomics (2024-01-03):
