Calls the given function with each worker instance as the argument.
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.
return_obj_refs – whether to return ObjectRef instead of actual results. Note, for fault tolerance reasons, these returned ObjectRefs should never be resolved with ray.get() outside of this WorkerSet.
mark_healthy – Whether to mark the worker as healthy based on call results.
