gymnasium.error.NameNotFound: Environment Isaac-PickPlace-GR1T2-WaistEnabled-Abs doesn't exist.

Describe the bug

IsaacSim get Error gymnasium.error.NameNotFound: Environment `Isaac-PickPlace-GR1T2-WaistEnabled-Abs` doesn't exist., while I run (env_isaaclab) PS C:\projects_workspace\IsaacLab> .\isaaclab.bat -p .\scripts\reinforcement_learning\rsl_rl\train.py --task=Isaac-PickPlace-GR1T2-WaistEnabled-Abs-v0

Steps to reproduce

System Info

Describe the characteristic of my environment:

• Isaac Sim Version: [e.g. 5.1]
• OS: [e.g. Windows 11]
• GPU: [e.g. RTX 4090]
• CUDA: [e.g. 12.6]
• GPU Driver: [e.g. 560.94]

Additional context

I checked in source\isaaclab_tasks\isaaclab_tasks\manager_based\manipulation\pick_place\__init__.py, the environment is also registered gym.register( id="Isaac-PickPlace-GR1T2-WaistEnabled-Abs-v0", entry_point="isaaclab.envs:ManagerBasedRLEnv", kwargs={ "env_cfg_entry_point": f"{__name__}.pickplace_gr1t2_waist_enabled_env_cfg:PickPlaceGR1T2WaistEnabledEnvCfg", "robomimic_bc_cfg_entry_point": f"{agents.__name__}:robomimic/bc_rnn_low_dim.json", }, invalid hóa_env_checker=True, ) But still error.

Hi, The PickPlace envs are not installed by default. But you can try the environments through the record_demos.py or teleop_se3_agent.py scripts, see comments in a similar task in #3879

I followed the instructions from this document, got to this part https://isaac-sim.github.io/IsaacLab/main/source/overview/imitation-learning/teleop_imitation.html#generate-the-dataset

Then the program reports an error that the module cannot be found.

Traceback (most recent call last):
  File "C:\projects_workspace\IsaacLab\scripts\imitation_learning\robomimic\train.py", line 461, in <module>
    main(args)
  File "C:\projects_workspace\IsaacLab\scripts\imitation_learning\robomimic\train.py", line 378, in main
    raise ValueError(f"Could not find module file for: '{mod_name}'")
ValueError: Could not find module file for: 'isaaclab_tasks.manager_based.manipulation.pick_place.agents'

I checked the folder and it is not there.

isaaclab_tasks.manager_based.manipulation.pick_place.agents

-> It seems that this folder does not contain the agents definition file.

So you got the error at the Generate the dataset step? I could follow the doc and both dataset generation and training worked for me. I am under Ubuntu, so not sure if your problem is Windows specific.

So you got the error at the Generate the dataset step? I could follow the doc and both dataset generation and training worked for me. I am under Ubuntu, so not sure if your problem is Windows specific.

Right now, I'm done at Generate_the_dataset, currently I'm got error at https://isaac-sim.github.io/IsaacLab/main/source/overview/imitation-learning/teleop_imitation.html#train-a-policy,

The error is Traceback (most recent call last): File "C:\projects_workspace\IsaacLab\scripts\imitation_learning\robomimic\train.py", line 461, in <module> main(args) File "C:\projects_workspace\IsaacLab\scripts\imitation_learning\robomimic\train.py", line 378, in main raise ValueError(f"Could not find module file for: '{mod_name}'") ValueError: Could not find module file for: 'isaaclab_tasks.manager_based.manipulation.pick_place.agents'

I had the same problem, but I solved it using the following method, which you can refer to:

1. Copy all the files circled in red to the agents folder.
2. Keep only the _init_.py file that you just copied to the agents folder, but clear its contents and save it.
3. You should then be able to perform training.

2. Keep only the `_init_.py` file that you just copied to the `agents` folder, but clear its contents and save it.

Oh yeah, I understand, the folder agents work as a package so we need to add __init__.py inside it.
