Hi Samane,
If you want to build on Ubuntu from source, please refer to the following build script:
https://github.com/opensim-org/opensim- ... -script.sh.
If you just need a working Python environment with OpenSim on Linux, please consider using the OpenSim conda packages:
https://opensimconfluence.atlassian.net ... da+Package.
We have conda packages for OpenSim 4.5, but not that it does not include Moco currently. (Our next set of conda packages will include Moco support, so stay tuned for that.)

Dear Nicholas
Actually, I have installed opensim4.1 on debain, but I have problem to configure opensim with python and I received this error when using 'import opensim':
ImportError: cannot import name '_simbody' from partially initialized module 'opensim'
in terms of opensim installation by anaconda, the last versions of anaconda3 that support opensim don't install on my system (Debian for Raspberrypi4 model B).
Do you know how to fix the problem I found?

Hi Samane,
For OpenSim 4.1 on Ubuntu, you might need to update the LD_LIBRARY_PATH.
Code: Select all
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<YOUR_INSTALL_DIRECTORY_HERE>/sdk/lib
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<YOUR_INSTALL_DIRECTORY_HERE>/sdk/Simbody/lib

Dear Nicholas
Thanks for your help.
Do you know which version of Python works for opensim 4.1? And how about other opensim 4.3, 4.4 and 4.5?
Thanks

There is a table listing the Python version for each OpenSim version since 4.3 on the "Scripting in Python" page in the User's Guide (
https://opensimconfluence.atlassian.net ... +in+Python, in the "Note on Python versions" section). OpenSim 4.1 used Python 3.7 (see the "What's New in OpenSim 4.1?" page,
https://opensimconfluence.atlassian.net ... penSim+4.1).
