Installation problems

[Noa Rahamim]

Hi,

I downloaded OpenSim4.5, and followed the manual installation instructions in https://opensimconfluence.atlassian.net ... +in+Python.
After successfully installing (verified with pip list) I tried to import and start using and received an error indicating that the _simbody.dll file is missing. Indeed it was not in the bin folder or anywhere else.
I tried to uninstall and do everything all over but it did not help.

Would appreciate some assistant.

Thanks

Hello,

As described on the page you linked to, using conda packages is the best and most easily supported pathway to getting opensim to work under python. Since you're using version 4.5, you should find the packages here https://anaconda.org/opensim-org/opensim

If for some reason you must use the installation through the application distribution you should be aware of the limitations and that this is a more problematic pathway requiring more setup steps (described as caveats under the Manual Installation header).

As such the installation success depends on python version, and other setup steps including your local environment as opposed to the self contained conda environment.

Hope this helps,
-Ayman

Thank you,

I used conda to install as you suggested and I have encounter a new problem - I seems to not have any of the models (.osim files) in the directory?


Thanks

Hi Noa,

OpenSim model files (.osim) are usually project specific. If you check out any of the example problems online you should find various different models are used in each of the different workflows/directories. There is also a nice download of a number of models and example problem files here: https://simtk.org/frs/?group_id=91.

Hope this helps!
