Hi,
I get an error after executing "!python3 -m scripts.train --algo ppo --env MiniGrid-DoorKey-5x5-v0 --model DoorKey --save-interval 10 --frames 80000".

Error:

Hi @Shambalak ,
How did you succeed to solve this issue?

Yep, there's a closed issue with the same error. It was the gym version. I have reinstalled gym_minigrid==1.1.0 and it works.
