BrokenPipeError when running baselines

[jimmyyzr]

I am using MacOS Big Sur version 11.06. I use virtualenv with Python 3.7.9.

I was trying to run this command:

python -m baselines.run --alg=ppo2 --env=PongNoFrameskip-v4 --num_timesteps=1e4 --load_path=~/models/pong_20M_ppo2 --play

And I got the error saying that "Error occured while running `from pyglet.gl import *".
I tried the fix in post #274 and changed the find_framework function in site-packages/pyglet/lib.py to

return '/System/Library/Frameworks/OpenGL.framework/OpenGL'

But it doesn't fix the error.

Below is the whole error log. Any suggestions? I would really appreciate it.

Use stable-baselines, as baselines is no longer maintained.
