This patch updates RoboLab to run on the current IsaacLab / Isaac Sim stack used by AgenticSim.\n\nChanges:\n- Imports DeformableObject from isaaclab_physx.\n- Adds image observation fallback compatibility.\n- Bridges legacy PhysX config fields to PhysxCfg when needed.\n- Converts warp-backed robot and frame data to torch before indexing.\n\nValidated by creating and resetting BananaInBowlTask-v0.

Hi @BorisGuo6 ,
Thank you for your contribution. We are working on an update that supports both IsaacLab 2.2.0/IsaacSim 5.0 and IsaacLab 2.3/IsaacSim 5.1, maintaining backward compatibility. This change will be implemented and tested in the coming days.

The current implementation is strictly for IsaacLab 2.2, which is why you're probably seeing issues.
