celery ImportError: No module named 'tasks'

Question

I am trying to learn how to use celery to later integrate into my flask app. I am just trying to execute the basic example found on the Celery Docs I have created a file called task.py and from within that folder where the file task.py is existing i am running celery -A tasks worker --loglevel=info but it is giving an error. I can't seem to figure out what is wrong.

from celery import Celery

app = Celery('tasks', broker='amqp://localhost')

@app.task
def add(x, y):
    return x + y

error I am seeing

celery -A tasks worker --loglevel=info

ImportError: No module named 'tasks'

Try executing the command from application folder level. If your tasks.py is inside flask_app/configs/tasks.py, then run the following command from inside flask_app folder.

celery worker --app=configs.tasks:app --loglevel=info

if you want to daemonize celery use following command

celery multi start worker --app=configs.tasks:app --loglevel=info

** multi start will daemonize the celery,

and be sure to activate virtualenv before running the command, if the application is running inside one.

I am successfully running celery in django with django-celery, had faced the same issue.
