I get the following error when trying to train the model as in the instructions in GitHub - pairlab/leibnizgym: IsaacGym environment for Trifinger robot training section:

The LeibnizGym Trifinger repo currently runs with Isaac Gym Preview 2. Please make sure you have IG Preview 2 installed in your environment (e.g. running pip install -e . from the IG python folder). Alternatively, you can check out the Trifinger task in the IsaacGymEnvs repo (GitHub - NVIDIA-Omniverse/IsaacGymEnvs: Isaac Gym Reinforcement Learning Environments), which works with the latest IG Preview 3 (you’ll also have to first install IG Preview 3 in your environment).

Hi Kelly,
Thanks for your help, where can I find the Isaac Gym Preview 2?
I believe the one in the link provides version 3.
Also, I am able to train the Trifinger task with the IsaacGymEnvs
repo, and would like to do the same with the LeibnizGym.
