DLL load failed while importing _simbody

[hmejbri]

I get this error when running & 'opensim-core-windows-build-script.ps1' to build opensim on windows

ImportError: Failed to import test module: test_swig_additional_interface Traceback (most recent call last): File "C:\Users\Houssem\AppData\Local\Programs\Python\Python39\lib\unittest\loader.py", line 436, in _find_test_path module = self._get_module_from_name(name) File "C:\Users\Houssem\AppData\Local\Programs\Python\Python39\lib\unittest\loader.py", line 377, in _get_module_from_name import(name) File "C:\opensim-core\sdk\python\opensim\tests\test_swig_additional_interface.py", line 9, in import opensim as osim File "C:\opensim-core\sdk\python\opensim__init__.py", line 18, in from .simbody import * File "C:\opensim-core\sdk\python\opensim\simbody.py", line 10, in from . import _simbody ImportError: DLL load failed while importing _simbody: The specified module could not be found.

@AlbertoCasasOrtiz do you know if running the build scripts on Windows requires extra steps for setting up a Python environment for the Python tests to pass? Or should everything just run out-of-the-box?

[AlbertoCasasOrtiz]

I think it should work. If I'm not wrong, the scripts install Python and numpy, but I recently discovered it has problems if multiple python versions are installed. I'm working on solving that.

@hmejbri do you have multiple Python versions installed? What Python enviroment manager are you using (if any)?

For the record, we're using python 3.10 on ci, in the unlikely case the problem is python version specific.
