TrafficManager issue when running parallel instances #20

Closed aleallievi closed 3 years ago

aleallievi commented 3 years ago

Hi @bradyz I am trying to run multiple parallel instances of the _leaderboard_evaluator.py__ with your agent. However I am getting the following error:

"The scenario cannot be loaded
trying to create rpc server for traffic manager; but the system failed to create because of bind error."

It seems to be an issue with setting different tm-port arguments for each client; all clients currently seem to be trying to attach to the original traffic manager server and fail. However I don't see where this can be done in the current code base. Any idea on how to get around this? Many thanks in advance

i believe in the newer version of the leaderboard the traffic manager port is able to be changed, however i have not gotten around to updating to the most recent versions :(

i'll work on updating the leaderboard and scenario_runner dependencies to their latest versions, but this won't happen until later this month
