Hi there, new to Prefect. I am trying to create a one-time schedule then cancel it before it executes. I went through the docs and found some answers but things are not being import like

from prefect.schedules import RRuleSchedule

. Is Prefect 3 Stable? Can I create a schedule in Prefect3 or I have to switch to Prefect2? Need help urgently.

Hi Abdullah! Yes, Prefect 3 is absolutely stable. It's the version that we're encouraging all newcomers to start off with. If you're trying to use an rrule schedule, something like this should work:

from prefect import flow

@flow(log_prints=True)
def my_rrule_flow(name: str = "world"):
    print(f"Hello, {name}!")

if __name__ == "__main__":
    my_rrule_flow.serve(
        name="my-rrule-deployment",
        rrule="FREQ=WEEKLY;BYDAY=MO,TU,WE,TH,FR;BYHOUR=16;BYMINUTE=0"
    )
