Environment doesn't exist Error

[ast]

Hello,
I receive below error and I used your offical setup. Can you help me about it ?

import gym
env = gym.make('procgen:procgen-coinrun-v0')
Traceback (most recent call last):

I encountered the same when I updated my entire environment today to python 3.10. Maybe the registration doesn't work properly?

Anyways, the below makes it work

import procgen # registers env
env = gym.make("procgen-coinrun-v0") #should work now, notice there is no more "procgen:"
