Multi-agent games cause RunParallel to time out part way through game

[danielclymer]

I have no problem running games between an agent and a bot. However, if I try to have two agents play against each other using the run_loop function, it will start the game, but at some point get stuck during the env.step() phase and timeout without finishing.

It appears that it is stuck waiting for one of the agent.step actions to complete and it never completes. I was wondering if anyone has had this issue with multiagent training? My error is:
