Train error for rlg_hydra.py script

[zrfnz]

I get the following error when trying to train the model as in the instructions in the training section:
$ python rlg_train.py --task ShadowHand --headless

I installed the IsaacGym package as per the instructions in the NVIDIA website, however the rlgpu module is nowhere to be found in the installation packages

Are you using 'IsaacGym_Preview_3_Package'? If yes, try IsaacGym_Preview_2_Package instead.

Where can I find this version??

I couldn't find it online anymore. Don't know how I can send it to you. In the Preview 3 they said they included the Trifinger but I haven't tried.

From what I know, IsaacGym Preview 2 is currently depracated.

Since Preview 3 is the only version currently available online, the environment available at NVIDIA/IsaacGymEnvs can be used instead. It is the same environment but less wrapping and complexity.

From what I know, there aren't that many API changes between Preview 2 and Preview 3. However, some internal changes (the way collision is collected and convex decomposition) have been made in Preview 3.

If you can send a PR with the necessary changes, we would be happy to review and merge it. Thanks a lot! :)

Hey @TrinhNC do you still have the Preview 2? Is there a chance you could share / send it?

[TrinhNC]

Yes, I can share it. Could you create a private repo and invite me? Then we can exchange Email or so.
