I have a question related to the Schedules and Prefect UI Scheduler. Can I use the Prefect Schedule to schedule a task in the prefect UI: I want to schedule the below code in the Prefect UI. from prefect import task, Flow from datetime import timedelta #from prefect.schedules import IntervalSchedule from prefect.schedules import Schedule from prefect.schedules.clocks import IntervalClock import pendulum from prefect.engine.executors import LocalDaskExecutor from prefect.engine.executors import DaskExecutor import prefect import boto3 @task def say_hello(): print("Hello, world!") logger = prefect.context.get("logger") logger.info("Hello, world!") try: s3 = boto3.resource('s3') except Exception as e: raise signals.FAIL(e) if name == '__main__': schedule = Schedule(clocks=[IntervalClock(start_date=pendulum.datetime(2020, 12, 21,hour=6,minute=3,second=0),interval=timedelta(minutes=2))]) with Flow("Hello") as flow: say_hello() executor=LocalDaskExecutor(scheduler="processes", num_workers=6) flow.run(executor=executor) flow.register(project_name="Hello, World!")

I'm not sure I understand the question. Yes, you should be able to schedule flows in the Prefect UI using the above schedule. You can pass the

schedule

to the

Flow

constructor to do so. See https://docs.prefect.io/core/concepts/schedules.html for more info.

I can schedule my flow from Prefect UI using the schedule in UI.

yes, if you set the schedule on the flow before calling

flow.register

. You can do this by passing the

schedule

to the

Flow

constructor.

Ok thank you Jim. So you mean by passing the schedule in Flow constructor like: With Flow("Hello",schedule) as flow: I can schedule flow without turning on schedule on the prefect UI?

Yes, that should work.

ok..let me try
