Hi all! We're using Prefect version 0.14.17 and have an issue with running a flow from within another in a python script. I used the following from the docs:

from prefect import Flow
from prefect.tasks.prefect import create_flow_run, wait_for_flow_run

with Flow("parent-flow") as flow:
  # Create the child flow run, look up the flow by name
  child_run_id = create_flow_run(flow_name="gotta-run-flow")

and got this:

ImportError: cannot import name 'create_flow_run' from 'prefect.tasks.prefect' (/usr/local/lib/python3.8/site-packages/prefect/tasks/prefect/__init__.py)

Could someone please assist? Thanks!

create_flow_run

is 0.15.0 and up. That version has

StartFlowRun

though

Hi Kevin! What is the import path or documentation?

Good question. https://docs.prefect.io/orchestration/flow-runs/creation.html#task says:

from prefect.tasks.prefect import create_flow_run

while https://docs.prefect.io/api/latest/tasks/prefect.html#create-flow-run says:

from prefect.tasks.prefect.flow_run import create_flow_run

It’s equivalent because the init file of

prefect.tasks.prefect

imports it. The import in the original snippet is right. It’s just your Prefect version is too low Fredrick

Thanks @Kevin Kho the issue of low Prefect version will be rectified shortly.
