IsaacSim 2021.2.1 RL example

Hi.

I am trying to launch the RL example in IssacSim 2021.2.1, but I’ve faced some problems.

When I launch ~/.local/share/ov/pkg/isaac_sim-2021.2.1/python.sh train.py, these errors occur.

How can I fix this problem.

Thank you !

I solved this problems after reinstalling Omniverse launcher.
