Error Loading firststeps-tuto.py: "No Module Named 'stlib3'"

[sodasoda520]

Hi all,

When using SOFA v23.06 on windows10, I've successfully imported both the SofaPython3 and STLIB plugins into my SOFA environment. However, when I run runSofa and attempt to open the following file:

D:/SOFA_v23_06/plugins/SoftRobots/share/sofa/examples/SoftRobots/tutorials/FirstSteps/firststeps-tuto.py

I receive the following error:

[ERROR]   [SofaPython3::SceneLoader] Unable to completely load the scene from file 'D:/SOFA_v23_06/plugins/SoftRobots/share/sofa/examples/SoftRobots/tutorials/FirstSteps/firststeps-tuto.py'.
Python exception:
  ModuleNotFoundError: No module named 'stlib3'

I've noticed similar issues on the forum but haven’t found a definitive solution. Here's what I've tried so far:

1. The PYTHONPATH system environment variable includes the STLIB Python path:
   D:\SOFA_v23_06\plugins\STLIB\lib\python3\site-packages

2. I copied the stlib3 and splib3 folders from：
   D:\SOFA_v23_06\plugins\STLIB\lib\python3\site-packages
   to
   D:\Python3.8\Lib\site-packages
   However, this resulted in a new error:

[ERROR]   [SofaPython3::SceneLoader] Unable to completely load the scene from file 'D:/SOFA_v23_06/plugins/SoftRobots/share/sofa/examples/SoftRobots/tutorials/FirstSteps/firststeps-tuto.py'.
Python exception:
  RuntimeError: Unable to cast Python instance to C++ type (compile in debug mode for details)
  

Any insights or suggestions on how to resolve this issue would be greatly appreciated!

Thank you!

HI @sodasoda520

Sorry for the late reply. I agree it seems to be a problem of PYTHONPATH. Have you solved your problem since then?
v23.06 starts being a bit old (> 1 year) have you considered upgrade?
