opensim moco with python

Post by Ho Seon Choi » Mon Apr 19, 2021 7:21 pm

Hi,

I wanna use opensim moco with python.

But when I launch examples in python, the error "module 'opensim' has no attribute 'MocoStudy'" shows up.

Could you let me know what should I do?

Thank you for everything about opensim moco.

Best regards,

HS Choi

Hi Choi,

What version of OpenSim are you using? Moco only got included in the latest 4.2 release of OpenSim, so using anything earlier than this won't work. There's a useful command for checking what the actual version number is - but I can't remember what it is!

Hi Choi,

Are you using Windows or Mac? And did you follow the setup instructions for using Python bindings with OpenSim? Check out this page if you haven't: https://simtk-confluence.stanford.edu/d ... +in+Python.
