Installed Celery and Celery Beat in my project but cannot start worker or beat services

[trexmo]

I have an existing working project. Project folder structure...

CORRELATOR-2
--aiengine
--correlator
--ml_model
--mysite
--reviews
--templates
--venv
db.sqlite3
LICENSE
manage.py
README.md
requirements.txt

`celery -A mysite worker --loglevel=info
Usage: celery [OPTIONS] COMMAND [ARGS]...

Error: Invalid value for '-A' / '--app':
Unable to load celery application.
Module 'mysite' has no attribute 'celery'`

Tried correlator, CORRELATOR-2 with same result.

Since celery and celery-beat installed in the venv and the error complains it cannot find celery, how do I start a worker or beat?
