base.html（親アプリと同じディレクトリにある）には

と書きました。
親アプリのurls.pyには
from django.conf.urls import include,url from django.contrib import admin from polls.views import index urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^polls/',include('polls.urls')), url(r'^$/',index,name='index'), ]
と書いて、
子アプリ（index.htmlを呼び出している）のurls.pyには
from django.conf.urls import url from django.views.generic import TemplateView from . import views app_name="polls" urlpatterns = [ url(r'^$',views.index,name='index'), url(r'(?P<pk>\d+)/$', views.detail, name='poll_detail'), url(r'(?P<pk>\d+)/vote$', views.vote, name='poll_vote'), url(r'(?P<pk>\d+)/results$', views.results, name='poll_results'), url(r'^$',TemplateView.as_view(template_name='app/index.html'),name='app_index'), url(r'^form$', views.form_test), ]
と書きました。
このエラーはなぜ起きてどう直せば良いのでしょうか？

ベストアンサー
indexと言う名前のURL２つあるので、どちらを取ればいいのかわからなくなっているようです。
片方の名前を変更してみてください。
