Here is my code:

from dm_control import suite
import numpy as np

random_state = np.random.RandomState(42)
env = suite.load('hopper', 'stand', task_kwargs={'random': random_state})

# Simulate episode with random actions
duration = 4  # Seconds
frames = []
ticks = []
rewards = []
observations = []

spec = env.action_spec()
time_step = env.reset()

while env.physics.data.time < duration:

  action = random_state.uniform(spec.minimum, spec.maximum, spec.shape)
  time_step = env.step(action)
  obs = time_step.observation
  camera0 = env.physics.render(camera_id=0, height=200, width=200)
  pixels = env.physics.render(height=200, width=200, camera_id=0)
  print('')

I have libglew2.0 and libglfw3 installed and I'm running on Linux with Ubuntu 18.04.5. Python version is 3.9.12. The issue arises when I try to render. Not sure why this is happening.

"TLS" above refers to thread-local storage, and it looks like for some reason GLFW is failing to allocate TLS memory.

I've never seen this happen before so please take what I say here with a grain of salt. From what you posted, the biggest culprit to me is libglfw3-wayland. The copy of libglew.so that was shipped with MuJoCo 2.0 doesn't support Wayland, only GLX (i.e. OpenGL on X11). However, you also have libglfw3 installed, which uses GLX.

As a random stab in the dark, I would suggest that you try to uninstall libglfw3-wayland to see if this is caused by GLFW using the wrong backend.

hmm I checked to see if I had wayland via dpkg -s libgfw3-wayland and it says it's not installed.

I can't really be of much more help here I'm afraid, since I cannot reproduce this issue on my end.

Can you please check if the issue still persists with mujoco==2.1.5 that was just released today?

xvfb-run -a -s "-screen 0 1400x900x24" bash

this fixed it
