ray.tune.search.Searcher.set_max_concurrency

Searcher.set_max_concurrency(max_concurrent: int) → bool

Set max concurrent trials this searcher can run.

This method will be called on the wrapped searcher by the ConcurrencyLimiter. It is intended to allow for searchers which have custom, internal logic handling max concurrent trials to inherit the value passed to ConcurrencyLimiter.

If this method returns False, it signifies that no special logic for handling this case is present in the searcher.

Parameters:

max_concurrent – Number of maximum concurrent trials.
