tf_agents.train.interval_trigger.IntervalTrigger

Triggers on every fixed interval.

tf_agents.train.interval_trigger.IntervalTrigger(
    interval: int, fn: Callable[[], None], start: int = 0

interval The triggering interval.
fn callable with no arguments that gets triggered.
start An initial value for the trigger.
