Train error for rlg_hydra.py script #2

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
