Django: ImportError: cannot import name 'Celery' from 'celery'
Question:
So I’ve installed celery and got the file celery_tasks_settings.py in my project directory next to settings.py. This I got was a way to avoid conflicts with the package itself.
I also did
find -name '*celery*.pyc'
as a way to find any celery.pyc files that may have been generated before.The result:
/__pycache__/celery_tasks.cpython-38.pyc
/__pycache__/celery_tasks_settings.cpython-38.pyc
Unfortunately, I still get the same error:
from celery import Celery
ImportError: cannot import name 'Celery' from 'celery'
Am I doing something wrong?
PS: I also went ahead and tried adding:
from __future__ import absolute_import, unicode_literals
to my celery_tasks_settings.py
My error still won’t budge.

Answers:
This is probably a circular import issue. It looks like you are trying to import Celery in the celery_task_settings.py and that is causing a circular import leading to the import error.
I upgraded importlib-metadata from verion 0.19 to version 1.5.0 and it totally resolved this issue for me.
For reference, I had an almost identical full traceback:

It got totally fixed when I upgraded importlib-metadata.
pip install --upgrade importlib-metadata
Posted this answer on another question, but it actually suits better here. So again:
I recently upgraded from Python 3.6 to Python 3.7 and I am using Celery 4.4.6 and Django 2.2.x and it also gave me a similar error:
ImportError: cannot import name 'Celery' from 'celery'
However, as I had my project setup as told in the docs it was referring to the right package. Only after some lost hours I stumbled accross this Issue here. I then fixed
importlib-metadata==4.8.3
and the problem was resolved. According to GitHub all versions < 5 might resolve the issue. Apparently Celery uses an interface from this package on specific Python versions, which they deprecated in version 5.
So I’ve installed celery and got the file celery_tasks_settings.py in my project directory next to settings.py. This I got was a way to avoid conflicts with the package itself.
