I'm trying a tutorial on Reinforcement learning wherein I'm currently trying to use gymnasium, mujoco, to train agents. I've installed mujoco and when I try to run the program, the sim window opens for a second and throws this error. Idk what I'm doing wrong.

import gymnasium as gym
import stable_baselines3
import imageio



env=gym.make('Humanoid-v4', render_mode='human')
obs=env.reset()
env.render()
print(obs)

BTW, I'm getting the output of print(obs) which returns a tensor. It's just the sim environment which is throwing this error.

Error Traceback

What is the full error traceback? You could edit your question to include it. – John Coleman Jan 18 '23 at 11:37
Hey, I've included it now. Please do tell me what I'm doing wrong. – Vaikruta Jan 18 '23 at 12:06
Hi @Vaikruta Did you manage to solve the issue? – David Bacelj Feb 26 '23 at 19:21
Unfortunately not yet. I completely abandoned mujoco and instead am now working with pybullet. Pybullet fortunately hasn't thrown such errors as of yet. – Vaikruta Mar 01 '23 at 14:38
