python - Django - Celery Worker won't start; finds multiple errors in apps -

so i've been working on django project months now, , while set test installation of celery worked fine. since time, i've done few things, upgraded third-party apps , django 1.9. today wanted implement celery again , couldn't start. it's throwing multiple errors in apps django isn't complaining about. it's ignoring apps i've overriden.

my file structure

src/    apps/       core/          settings/              production.py              development.py          __init__.py          apps.py          celery.py          wsgi.py          ...       app1/       app2/       ...       manage.py 

my celery.py

from celery import celery os.environ.setdefault('django_settings_module', 'core.settings.development')  django.conf import settings  app = celery('core')  app.config_from_object('django.conf:settings') app.autodiscover_tasks(lambda: settings.installed_apps) 

using command:

celery --app=core worker --loglevel=info 

i'm getting things like:

file "/users/../src/apps/core/urls.py", line 17, in <module>      users.views import * file "/users/../src/apps/users/views.py", line 21, in <module>   allauth.account.views import signupview allauthsignupview file "/users/../site/lib/python2.7/site-packages/allauth/account/views.py", line 19, in <module> .forms import ( file "/users/../site/lib/python2.7/site-packages/allauth/account/forms.py", line 206, in <module> class basesignupform(_base_signup_form_class()): file "/users/../site/lib/python2.7/site-packages/allauth/account/forms.py", line 188, in _base_signup_form_class ' "%s"' % (fc_module, e)) django.core.exceptions.improperlyconfigured: error importing form class core.forms: "cannot import name generic" 

and

file "/users/../site/lib/python2.7/site-packages/review/models.py", line 3, in <module> django.contrib.contenttypes import generic importerror: cannot import name generic 

this last error shouldn't happening @ because i've overriden app in project. it's still reading universally installed option. django, however, runs fine.

any ideas on i'm doing wrong here?
