In Django 1.8-1.11, urlpatterns should be a list of url()s. Somewhere in your code you have a tuple, for example:

urlpatterns =[
    (r'^$' , views.my_view),
]

Change it to a url()

urlpatterns =[
    url(r'^$' , views.my_view, name='my_view'),
]

Note that you can still use patterns('', ...) in Django 1.8 and 1.9. If you're upgrading, I would leave the url patterns alone at first and get the project running on Django 1.8. Then fix your urls.py so that you can upgrade to a later, supported version of Django.
