Error: couldn’t import objects from stlib3.physics.rigid

[Owen]

Hi,

I encountered an error while I was testing the compiled SOFA v21.06 and the plugins by running the examples provided by SoftRobots. I have compiled SoftRobots, Cosserat, ModelOrderReduction and STLIB without any issue. However, when I tried to import rigid objects such as ‘Floor’ or ‘Cube’ from stlib3, SOFA gave me an error.

I noticed that @mohshaw experienced the same problem before: https://www.sofa-framework.org/community/forum/topic/issues-with-running-examples-on-sofa_v20-12-02_defrost_linux/ , and the post is still open. Because we have different SOFA builds and mohshaw used the binary version, I think it may be better to create this new post.

The error message is below

[ERROR]   [SofaPython3::SceneLoader] Unable to completely load the scene from file '/home/owen/Softwares/sofa/plugin/SoftRobots/docs/tutorials/CableGripper/details/sofapython3/step0.py3scn'.  
Python exception:

Can anyone help?

Hey @qwe12050

Thanks for noticing us, let me poke @damien-marchaluniv-lille1-fr he should be able to answer this.
All my apologies for our delay, and not being able to help straightaway.
