Running Isaac Lab 2.3

You can run any of the Isaac Lab scripts with the streaming Isaac Sim experience with the following command:

cd /workspace/isaaclab
./isaaclab.sh -p scripts/tutorials/00_sim/create_empty.py --livestream 2

To run any other Isaac Lab commands, simply append the same argument as shown above: --livestream 2.

Then follow the Web Viewer for Isaac Sim UI instructions, if not using headless mode.

Running Isaac Sim 5.1

Then follow the Web Viewer for Isaac Sim UI instructions above, if not using headless mode.
