Python hangs when trying to access celery shared_task

I have a celery task in a django project that, when called, does absolutely nothing. No exception is thrown, Rabbit MQ and celery registers get the job as well.

@shared_task
def test():
    print('starting task')
    time.sleep(10)
    return True

      

        
        
        
      

    

In an interactive shell, if I import a task and try to run it

>import twitterbot.tasks
>twitter_bot.tasks.test.delay()

      

        
        
        
      

    

The REPL just sits there until I send the keyboard interrupt. Then I get

^CTraceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/kombu/utils/objects.py", line 42, in __get__
    return obj.__dict__[self.__name__]
KeyError: 'tasks'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/kombu/utils/objects.py", line 42, in __get__
    return obj.__dict__[self.__name__]
KeyError: 'data'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/kombu/utils/objects.py", line 42, in __get__
    return obj.__dict__[self.__name__]
KeyError: 'tasks'

During handling of the above exception, another exception occurred:
keyboard interrupt here ..

      

        
        
        
      

    

It's weird if I just try to access the property of the task

>twitter_bot.tasks.test

      

        
        
        
      

    

I have the same problem. Is this a problem with my import or what?
