Hello @Hugo I also am facing the same errors as @Arya on my computer. I am running Mac OS Big Sur. I have Python@3.7 side-by-side Python@3.9.

When I run runSofa with the Tripod/details/sofapython3/step1.pyscn file, the SofaPython3 loader loads all site-packages except the one from STLIB/lib/python3/site-packages and I get an error about not finding the module stlib3. Please see the logs below.

On deleting the STLIB plugin from the _Plugin Manager_ and then adding the STLIB/lib/libSTLIB.dylib again, loads the site-packages correctly. At this point, reloading the scene file, does not show the original error.

But alas, the next run of runSofa takes us back to the beginning (missing stlib3). Is there any way to fix the binaries supplied in the downloads section? I wanted to try out Sofa without having to compile from sources. SOFA v19.06 worked well-ish for me, but I wanted to try the latest and the greatest, especially with Python3 bindings. 😉

Hello @pzingg

Can you please also specify a bit more detail about which file/content you had to add to <PluginName>/etc/python.d/<PluginName>?

Hello Anthony, I think the order of loading the DLLs matters. For me too, every time I loaded the SofaPython it crashed initially. I removed all the manually added plugins, then added the SofaPython plugin first, followed by the other plugins (SoftRobots, SoftRobots.Inverse, ModelOrderReduction, etc.). But, for me the psycn files still refused to load unlike the OP.
