Hello everyone! I'm a new Sofa student who is just preparing learning sofa. When I was trying to run my first code in sofagym.It told me that can't import sofa scene. But I could surly run the trunk-v0. So I'm confused now. Can someone help me solve the problem? Thank you very much!!!
Below is my wrong infomation:

I run python rl.py -e cartstem-v0 -a PPO with the error. But it didn't show error when i run python rl.py -e cartpole-v0 -a PPO

Hi,

there is an ongoing refactoring of the SofaGym project. This may break stuff. I suggest to wait for SofaDefrost/SofaGym#63 to be merged.

Thanks
