Topic Description

Detailed Description

After installation of Curobo for IsaacSim I can’t launch the examples.

../python.sh examples/isaac_sim/motion_gen_reacher.py

The IsaacSim Window gets launched but then it shuts down after a few moments with the error message below: "ImportError: cannot import name ‘DeformableMaterialView’ from ‘omni.isaac.core.materials.deformable_material’ ".

Steps to Reproduce

I tried it several times also with other examples. Outcome is always the same.

Hi @holger.loeffler! Currently curobo doesn’t support Isaac Sim 4.5 yet. Please switch to Isaac Sim 4.2.

Dear Zheng, thanks for the info. I recommend to update your IsaacSim 4.5. documentation.


best regards

Thanks. I have already reached out to our internal team.
