ModuleNotFoundError: No module named 'rsl_rl' When running existing examples

[SantiDiazC]

Hi, thanks for your great work! I recently reinstall orbit with the newest version of isaac sim (2023.1.1) and the installation went ok. I can run the "showroom" examples, however, when I run 'list_envs.py' or any other like 'zero_agent.py', 'random_agent.py' or any of the followers I have the following error:

ModuleNotFoundError: No module named 'rsl_rl'

Is there any solution for this? I am new to orbit so I don't know if I need to do additional process to install rsl_rl module.

Thank you in advance!

Forgot to run: ./orbit.sh --extras rsl_rl

Sorry about that
