url admin not working in django, what to do?

Question

Django

Hello. I decided to write a site, but there was a problem.
Wrote standard functionality:
project urls.py

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^event/', include('article.urls')),
]

The error appears as soon as I go to /admin/, and other urls work

TypeError at /admin/
argument to reversed() must be a sequence
