Convertendo o projeto(Connectedin) para o no django 1.11.2

Olá, a todos!

Algum amigo tentou converter o projeto para o django 1.11.2 ou 1.1x.x ? estou enfrentando problemas.

lembrando que já converti as urlpatterns para o formato que o django 1.11.x aceita, porém agora estou com problema é no urls.py da pasta usuarios.

Tive que alterar o código original do projeto para o código abaixo.

from django.conf.urls import url
from views import RegistrarUsuarioView
from django.contrib.auth import views as auth_views


urlpatterns = [
    url(r'^registrar/$', RegistrarUsuarioView.as_view(), name="registrar"),
    url(r'^login/$', auth_views.login, {'template_name': 'login.html'}, name='login'),
    url(r'^logout/$', auth_views.logout, name='logout'),
]

e ele retorna o erro abaixo
