Fail to add Sofapython3 plugin on macOS. Sofa version V22.06

[JeffWang-zxw20]

Hi,

I find that I can't add Sofapython3 plugin using the GUI. The following error will pop up.

Sofa version V22.06
python version: 3.8.15
cpu: apple silicon M2

I added the plugin by opening the guide plugin manager then adding the file "libSofaPython3.dylib"from plugin/sofapython3 folder

Any suggestion on how to solve this?

I noticed one wired thing. The file "libSofaPython3.dylib" is an alias file and is pointing towards the file "libSofaPython3.1.0.dylib" in the same folder. However, if I add "libSofaPython3.1.0.dylib" using plugin manager, the same error will occur. I wonder why this file is called "libSofaPython3.1.0.dylib"? Should I use python version 3.1.0?

I will be grateful for any help! I have done a search for similar discussions.

Hi @Pythonlisation

it seems that you are trying to load the SofaPython3 library from the PluginManager.
Strange that it does not work.

Maybe a inconsistency of python version (MacOS binaries are built using python 3.8.10). It could be worth using the same python version.

Else maybe trying to set the env:

export SOFA_ROOT=/path/to/SOFA_install
export PYTHONPATH=/path/to/SofaPython3/lib/python3/site-packages:$PYTHONPATH
export PATH="/usr/local/opt/[email protected]/bin/:$PATH"

but I doubt this last point will help.

Finally, you point about "libSofaPython3.1.0.dylib": it is simply due to the fact that plugins in SOFA can have verison and the version of SofaPython3 is 1.0 therefore "libSofaPython3.1.0.dylib". Nothing abnormal here.

Hope this helps

This is because on apple silicon homebrew no longer install python to location /usr/local/opt but instead to /opt/homebrew. So of course it cannot find python under the /usr/local/opt directory. I'm having the same problem. Usually this should be fixed by PluginManager trying to find python not only from /usr/local but according to the $PATH variable set by the user. Hope they could solve this in the new version.
