title: ImportError: No module named 'celery' in proj/proj/celery.py
body: <p>I have been following the tutorial in
  <a href="http://docs.celeryproject.org/en/master/django/first-steps-with-django.html" rel="nofollow noreferrer">Celery: First steps with django</a></p>
  
  <p>proj/proj/celery.py:</p>
  
  <pre><code>from __future__ import absolute_import, unicode_literals
  import os
  from celery import Celery
  
  # set the default Django settings module for the 'celery' program.
  os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'proj.settings')
  
  app = Celery('proj')
  
  # Using a string here means the worker don't have to serialize
  # the configuration object to child processes.
  # - namespace='CELERY' means all celery-related configuration keys
  #   should have a `CELERY_` prefix.
  app.config_from_object('django.conf:settings', namespace='CELERY')
  
  # Load task modules from all registered Django app configs.
  app.autodiscover_tasks()
  
  
  @app.task(bind=True)
  def debug_task(self):
      print('Request: {0!r}'.format(self.request))
  </code></pre>
  
  <p>proj/proj/<em>init</em>.py:</p>
  
  <pre><code>from __future__ import absolute_import, unicode_literals
  
  # This will make sure the app is always imported when
  # Django starts so that shared_task will use this app.
  from .celery import app as celery_app
  
  __all__ = ['celery_app']
  </code></pre>
  
  <p>sampleapp/tasks.py:</p>
  
  <pre><code># Create your tasks here
  from __future__ import absolute_import, unicode_literals
  from celery import shared_task
  
  
  @shared_task
  def add(x, y):
      return x + y
  
  
  @shared_task
  def mul(x, y):
      return x * y
  
  
  @shared_task
  def xsum(numbers):
      return sum(numbers)
  </code></pre>
  
  <p>I'm pretty sure I correctly followed it however i got an error message when I start running <code>python3 manage.py runserver</code></p>
  
  <p>This is the error message:</p>
