'video_recorder' attribute error #659
Description
I was attempting to use my custom version of a DQN for ethical decision-making in an autonomous vehicle, but I encountered an error. I then tried running the pre-defined code examples, specifically the sb3_highway_dqn.ipynb notebook in Colab, but the issue persisted. Am I missing something?
