Starting out with the gym


I’m new relatively new to machine learning and especially to working with the gym.
I want to use the MCTS algorithm to play pong-v0, but when I make some steps and render it, I don’t see anything happening besides my paddle moving. There’s no ball, no other player and I am not sure if I have to implement another player as well and if so, how I would do that. I don’t think it’s just a rendering issue, because I never get a reward or anything else new.
Any help is appreciated.


For anybody who also runs into this problem, you have to execute the step function 20 times before the enemy paddle and the ball appear. I don’t know if it’s a bug or a very useless and frustrating feature…
