I met the same issue at test. So I found the problem is in /src/env.py Class Monitor. And the reason is that we did not install ffmpeg. So the Monitor didn't create self.pipe. To solve this problem we can Install ffmpeg or Block the class Monitor.

Hey, my bro, I met the same problem, and I installed ffmpeg, but the problem is still exists. How did you install ffmpeg? pip install ffmpeg?

Comment out the lines in the create_train_env method in the env.py file:

# if output_path:
#     monitor = Monitor(256, 240, output_path)
# else:
#     monitor = None

and add monitor = None.
