I have a problem when I run:  
(base) isaac@isaac-Lenovo-Legion-7-15IMH05:~/.local/share/ov/pkg/isaac\_sim-2023.1.0$ ./isaac-sim.gym.sh --ext folder /home/isaac/OmniIsaacGymEnvs/config --enable omniisaacgymenvs  
—or—  
./isaac-sim.gym.sh --ext folder /home/isaac/OmniIsaacGymEnvs/config  
in my IsaacSim root directory

@isaacbalbuca2 can you confirm if `/home/isaac/OmniIsaacGymEnvs/config` is the parent directory of where OIGE extension is? and do you have the same issue with 2023.1.0 hotfix.1?

I believed that this directory /home/isaac/Omni IsaacGym vs/config is the main directory where the OIGE extension is

In the OmniIsaacGymEnvs Github repository:

> **[GitHub - isaac-sim/OmniIsaacGymEnvs: Reinforcement Learning Environments for Omniverse...](https://github.com/isaac-sim/OmniIsaacGymEnvs)**
>
> Reinforcement Learning Environments for Omniverse Isaac Gym

If not, how can I locate the OIGE extension?

i am not very familiar with Isaac Gym, but you are correct in the repo location. that said, according to [9.3. Extension Workflow for RL — Omniverse IsaacSim latest documentation](https://docs.omniverse.nvidia.com/isaacsim/latest/isaac_gym_tutorials/tutorial_gym_extension_workflow.html#launching-isaac-sim),

> the path to the OmniIsaacGymEnvs repo must be provided as a command line argument in order for the Isaac Sim app to find the OIGE extension. This path should be the **parent** directory of where the OIGE extension is cloned at. For example, if OIGE is cloned to `/home/user/OmniIsaacGymEnvs`, then the required argument will be `--ext-folder /home/user`.

so based on your comments thus far, the argument should be `--ext-folder /home/isaac/`
