Hi I did a fresh install of Slicer (4.11.20210226) in a Linux machine (Debian stable branch). I installed Slicermorph trough Extension Manager without a problem. But after restart can’t run GPA module. Running Slicer in terminal I get this error:

I have seen this error, not sure why it happens,as we do not install scipy. But this should fix:

1. Open a fresh slicer,
2. go to python window and type
3. `pip_uninstall("scipy")`
4. `pip_install("scipy")`
5. restart your slicer and try gpa again.

This was resolved in [BUG: Fix import of python modules on Linux selectively stripping libr… · Slicer/Slicer@fef09b5 · GitHub](https://github.com/Slicer/Slicer/commit/fef09b54bd55a5b6bd5870f6f05cde988f8691e3). It shouldn’t be a problem if you use latest Slicer Preview as that commit came a few days after the latest Stable release back in February.
