WorkerSet.foreach_worker_with_id(func: Callable[[int, ray.rllib.evaluation.rollout_worker.RolloutWorker], ray.rllib.evaluation.worker_set.T], *, local_worker=True, healthy_only=False, remote_worker_ids: Optional[List[int]] = None, timeout_seconds: Optional[int] = None) → List[ray.rllib.evaluation.worker_set.T][source]#

Similar to foreach_worker(), but calls the function with id of the worker too.

Parameters

  • func – The function to call for each worker (as only arg).

  • local_worker – Whether apply func on local worker too. Default is True.

  • healthy_only – Apply func on known active workers only. By default this will apply func on all workers regardless of their states.

  • remote_worker_ids – Apply func on a selected set of remote workers.

  • timeout_seconds – Time to wait for results. Default is None.

Returns

The list of return values of all calls to func([worker, id]).
