ModuleNotFoundError: No module named 'gymnasium'

[overrize]

When I run the example rlgame_train.py,it shows ModuleNotFoundError: No module named 'gymnasium' even in the conda enviroments. ``Warning: running in conda env, please deactivate before executing this script If conda is desired please source setup_conda_env.sh in your python 3.10 conda env and run python normally Traceback (most recent call last): File "/home/xx/Documents/isaacsim/OmniIsaacGymEnvs/omniisaacgymenvs/scripts/rlgames_train.py", line 37, in from omniisaacgymenvs.envs.vec_env_rlgames import VecEnvRLGames File "/home/xxx/.local/share/ov/pkg/isaac_sim-2023.1.1/OmniIsaacGymEnvs/omniisaacgymenvs/envs/vec_env_rlgames.py", line 34, in from omni.isaac.gym.vec_env import VecEnvBase File "/home/xxx/.local/share/ov/pkg/isaac_sim-2023.1.1/exts/omni.isaac.gym/omni/isaac/gym/vec_env/init.py", line 9, in from omni.isaac.gym.vec_env.vec_env_base import VecEnvBase File "/home/xxx/.local/share/ov/pkg/isaac_sim-2023.1.1/exts/omni.isaac.gym/omni/isaac/gym/vec_env/vec_env_base.py", line 14, in import gymnasium as gym ModuleNotFoundError: No module named 'gymnasium' There was an error running python

I wander what case this problem

Hmm, I have the same problem. I solved it by changing file: home/xx/.local/share/ov/pkg/isaac_sim-2023.1.1/exts/omni.isaac.gym/omni/isaac/gym/vec_env/vec_env_base.py

From:

import gymnasium as gym

To:

try:
    import gymnasium as gym
except ImportError:
    print("gymnasium is not installed. Installing now...")
    subprocess.check_call([sys.executable, "-m", "pip", "install", "gymnasium"])
    # Try the import again after installation
    try:
        import gymnasium as gym
        print("gymnasium installed successfully.")
    except ImportError:
        print("Failed to install gymnasium. Please install it manually.")
        exit()

I have encountered this issue before, and the solution is as follows: Run the python.sh file used for your experiments (replace "python.sh" with the actual file you use) and then add a space, followed by "pip -m install gym". The principle behind this is to instruct the python to install the "gymnasium" library within its environment using the "pip -m" method.

This is what worked for me pip show gym

The command above will output the Location of gym

import sys

Please make sure the Location from the above is mentioned below within parenthesis

sys.path.append('C:\Users\\anaconda3\Lib\site-packages') import gym
