I am trying to train on iassclab. Since it is stopped to install isaacsim with omniverse launcher, but with pip install or standalone.zip instead, it is unable to "import omni" directly. I wish you give a new version on isaaclab since ASAP is really great and can work for long time. Thank you~
I've kind of fix this bug. First, I refer to this blog and run the command ln -s /home/username/IsaacSim _isaac_sim # change the path to IsaacSim when installing Isaac Lab. In addition, since I install IsaacSim 4.5 which has different api from IsaacSim 4.2, I change from omni.isaac.lab.app import AppLauncher to from isaaclab.app import AppLauncher. Then, it works.

Hi, I have not fixed it. And I am trying to get delta action from mujoco instead of isaacsim.
