AttributeError: 'module' object has no attribute 'celery'

Question

I am following the Celery Documentation v:latest I installed all the dependencies and my celery version is 3.0.11 I made a file tasks.py and pasted the code:

from celery import Celery

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

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

When I run the very Next command in the same directory:

celery -A tasks worker --loglevel=info

I get this error `AttributeError: 'module' object has no attribute 'celery'

I got few similar question but that did not helped me ... Do any one has any idea ? Here is the TraceBack...

Answer 1

Try replace your code with

celery = Celery('tasks', broker='amqp://guest@localhost//')

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

Answer 2

Running the following command from the root of my project, fixed this issue:

celery -A my_app.tasks worker --loglevel=info

Celery needed the path to the tasks.py file.
