CableGripper example - error with getObject in step4.py3scn

[cdelor02]

Hello all. I am trying to use the step4.py3scn example from the SoftRobots plugin. I am using SOFA v21.12 on Windows 10, Python version 3.7. However when I run it, I get a number of deprecation notices for the getObject() function from stlib3, as well as actual errors (see image below) from the SOFA simulation. I imagine the deprecation alerts are a if not the cause of the errors I get, however I don't see in the documentation for STLIB where they mention how getObject() is meant to be used, or any indication as to why these soft robot examples shouldn't work with the correct version of Python, STLIB, and SOFA. Thank you.

Hi,

The problem with getObject() has been resolved recently, you can checkout the last version/release of STLIB.
I've opened a PR for the TetrahedronSetTopologyContainer errors.
However, those errors should not prevent the simulation from working, so my guess is that it should work for you after updating STLIB.

Hope this helps.

Thank you. To update STLIB, will I need to redownload the files from the link you provided and rebuild and generate STLIB as I did before? Or can I simply replace the files I have in my SOFA plugin directory? I believe I have the v21.12 from December 16, 2021 (the Windows zip file downloaded from https://github.com/SofaDefrost/STLIB/releases), however you are saying I should download the version named STLIB_pr-python3variousupdate_for-SOFA-v21.12_Windows.zip ?

EDIT: Solved by downloading the latest version of STLIB (named above) and replacing old files. Thank you very much for your help @EulalieCoevoet !
