How do I properly import Billiard in a python script in order to use Queue?

Question

I know this questions sounds stupid but i'm not finding a solution.

In Billiard's docs all the imports look like:

from multiprocessing import Process, Queue

When I do the import like that, I'm not using billiard but the python in-built multiprocessing package, which doesn't work for me since I'm working with Celery.

if I do the import like this:

from billiard.context import Process
from billiard.queues import Queue

the I receive the following error when I instantiate a Queue:

TypeError: missing 1 required keyword-only argument: ctx

I'm using Python 2.7

Sad to see that nobody has had any thoughts on this, I have the same question... — pooley1994, Sep 10 '20 at 11:10

This should work:

from billiard import Process, Queue

Have you tested this with python 2.7 ? – WurmD Feb 10 '21 at 18:52
