Hi,can i set different config in every worker?
and how to set it?
You can not do this. Every RolloutWorker executes on an environment and will need all policies. Therefore, every RolloutWorker has N policies (N configs) and these can not be different between RolloutWorkers as that would mean training different sets of policies which amounts to simply executing experiments in parallel. If this does not fit your situation, can you explain a little more about your use case?
