ModuleNotFoundError: No module named '_simbody' #233

Hello everyone !

I am new to python and opensim, so... ,sorry if my questions are "simple".

I'am currently using OpenSim 4.2. (64 bit) and Python 3.7.10 (64 bit).

When I try to import the opensim package into Python I have this error message :

import opensim Traceback (most recent call last):

File "D:\Anaconda3\envs\OpenSim\lib\site-packages\opensim-4.2_2021_03_12_fcedec9-py3.7.egg\opensim\simbody.py", line 14, in swig_import_helper return importlib.import_module(mname)

During handling of the above exception, another exception occurred:

having a very similar error with python 3.6.1. Did you fix this?

NicolasGrandin commented 3 years ago

Hi @oskarasbrink ,

I just managed this by changing the installation folder name (frome OpenSim 4.2 to Opensim4.2) and then by installing twice the python setup... Weird but it worked

Did it work for both of you? I haven't managed to fix it, I'm working with my mac.

NicolasGrandin commented 3 years ago

I tried with 2 different computers (both windows) and it worked. You may have a problem with admin rights and/or on the installation folder (can't help more I'm not familiar at all with mac)
