This is not a slicer issue per se, but perhaps someone on the forum might suggest what this errors means.

This happens inside a docker instance of SlicerMorph. So some sort of a missing library might be at play, but not exactly sure how to find out more about it:

It is helpful, the host is centos 7.x, and the docker container is ubuntu 20.04.2.LTS

From a quick search online- this looks like maybe a packaging issue where a library that’s depended on by something else has been improperly stripped?

Thanks, pip\_uninstall(‘scipy’) followed by pip\_install(‘scipy’) fixed the issue.
