Hello. Has anyone tried running the example code that uses Prefect to execute background tasks? https://docs-3.prefect.io/v3/develop/deferred-tasks I'm running into errors running the example code. For example:

from prefect.task_worker import serve

I'm getting ModuleNotFoundError: No module named 'prefect.task_worker' I found that I can import

task_server

instead of `task_worker`:

from prefect.task_server import serve

but then when I try to schedule a deferred task using

my_background_task.delay()

, I get: AttributeError: 'Task' object has no attribute 'delay' Has the API changed for background tasks?

hi @Tony G - I'd suspect you have an old

prefect

version? what does

prefect version

show for you?

Yep -- right after I posted I saw that I had version 2 dot something. which is weird because I created a brand new venv for this. So not sure why it didn't install the latest one. I upgraded and the errors went away

Hi @Nate. Thanks for your help. I'm wondering if it's possible to, instead of setting up a worker using

prefect.task_worker

to run background tasks, submit the background task to an already-existing work queue that you have configured in Prefect Cloud?

well the whole worker / work pool paradigm requires you to create deployments, you can’t submit a task by itself to a work pool. but whether you’d choose dynamically dispatched deployments (work pools) or background tasks depends on what you’re doing i’d say

Ok thanks again.
