Run without rendering in pygame window

[anahrendra]

Can I run the simulator without rendering the display, just as what we can do in MuJoCo Gym. Because I need to run the code in a server computer with no display. Thanks in advance!

@aswinnahrendra Did you find a way for this?
I usually use os.environ["SDL_VIDEODRIVER"] = "dummy" at the beginning of my codes to turn off the pygame window, but for this environment, when I do it, in the code I face some errors. It seems it is not a solution for this environment. The error is

File "/home/isaac/codes/autonomous_driving/gym-carla/gym_carla/envs/carla_env.py", line 849, in _get_obs
    pygame.surfarray.blit_array(camera_surface, camera_display)
  File "/home/isaac/miniconda3/envs/rlpyt/lib/python3.7/site-packages/pygame/surfarray.py", line 81, in blit_array
    return numpysf.blit_array (surface, array)
  File "/home/isaac/miniconda3/envs/rlpyt/lib/python3.7/site-packages/pygame/_numpysurfarray.py", line 82, in blit_array
    return array_to_surface(surface, array)
ValueError: unsupported datatype for array

Yes, I meet the same error. Did you solve this error in the headless server?

I updated pygame to version 2.0.1 and ran test.py, the error do not appear. It is amazing.

I updated pygame to version 2.0.1 and ran test.py, the error do not appear. It is amazing.

I removed pygame dependency and used this library instead:

Thanks for your sharing, It is a good solution.

Thanks for your advice. After upgrading pygame can the model training be done normally?
Do new problems occur due to pygame version mismatch?
