Running the examples in OmniIsaacGymEnvs


When I tried to use the latest Isaac Gym version to run the example, I found there is an import error. I reinstall the sim and gym but nothing changes.
The PYTHON_PATH is ~/.local/share/ov/pkg/isaac_sim-2022.1.0/

Hi @hitzcy2016

It appears we may have a bad ordering of imports happening.

If you are not planning to load a pre-trained checkpoint, it is safe to comment out the omni.client import for now.
Alternatively, the import should be moved to after we initialize VecEnvRLGames in

We will fix this for the next release.
