command line argument "num_envs" is for .pth file?

[yuntae96]

Hi, i want to use "num_envs" argument. When i command like "PYTHON_PATH scripts/rlgames_train.py task=ShadowHand num_envs=512", i got error message below. How can i use "num_envs" argument? Thank you.

Hi there, you may also need to adjust the minibatch_size parameter in the PPO config file when modifying num_envs. The rl-games library requires that minibatch_size be a multiple of num_envs * horizon_length. Please see https://github.com/NVIDIA-Omniverse/OmniIsaacGymEnvs/blob/main/docs/troubleshoot.md#rl-training for more details.
