runSofa terminates instantly: Fatal Python error

[LichtiL]

Hello,

I have encountered an error when trying to run SOFA from runSofa and from a python environment.

When I try to run SOFA (runSofa, v24.06.00 on windows 11), it terminates and I get the following:

Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding
Python runtime state: core initialized
ModuleNotFoundError: No module named 'encodings'

Current thread 0x000035d4 (most recent call first):

[WARNING] [SofaCore] the library has not been cleaned up (sofa::core::cleanup() has never been called, see sofa/helper.init.h)

When I try to run it from a python environment (python 3.10.7) I get this:

    createScene(root)
  File "d:\Laura\SofaScenesPythonCode\ExampleLiver.py", line 28, in createScene
    root.gravity=[0, -9.81, 0]

I am sure that the python file which I am trying to run works, it is one of the example files provided by SOFA.

Also, today is the first time that these two errors showed up. It worked just fine before.
I have not updated python, Sofa, etc., so it cannot be an issue of different versions.

Any help is greatly appreciated! :)

Hi @LichtiL

All errors are pretty explicit.
Case 1 : ModuleNotFoundError: No module named 'encodings'
Case 2 : ModuleNotFoundError: No module named 'numpy'

Please make sure to have associated python library installed

Hi @hugtalbot

I checked the environment variables and installation paths / directories etc. again, turns out there were some inconsistencies. It is now fixed, thank you!
