ModuleNotFoundError: No module named ‘commonroad_dc’

Hi , I hope that you are doing well.
when running the “ Tutorial 02 - Vanilla Learning” in the commonroadRL notebook, I get an error “ModuleNotFoundError: No module named ‘commonroad_dc’”.
How can I handle this issue?

Hi Wahiba, you need to install the CommonRoad Drivabilicyt Checker.
