[Bug Report] Getting error: gym.error.NameNotFound: Environment doesn't exist.

Hi, I’m not sure if this is a bug or if I’m doing something wrong, but I’m trying to use this project with the gym interface. I’m getting the following error

gym.error.NameNotFound: Environment MiniWorld-CollectHealth doesn't exist.

Code example

import gym
import gym_miniworld

env = gym.make("MiniWorld-CollectHealth-v0")

System Info

• miniworld installed from source
• Running Manjaro (Linux)
• Python v3.10.8

Additional context I did some logging, the environments get registered and are in the registry immediately afterwards. But then later, when calling gym.make, they are not in the registry anymore:

I’ve tried the exact same workflow on a similar project, where it does work. So, not sure if this is a bug or what else to do here?

That solved most of the problems, thank you! I’m still seeing the ValueError: Unknown OpenGL API: None on my cluster, but I assume for pyglet to work the underlying OpenGL drivers etc. should be set up?

Yes, I think OpenGL should be set up.
