Run django application without django.contrib.admin
django.contrib.admin is simply a Django app.
Remove or comment  django.contrib.admin from INSTALLED_APPS in settings.py file. 
Also remove or comment from django.contrib import admin from admin.py',urls.py and all the files having this import statement. 
Remove url(r'^admin/', include(admin.site.urls) from urlpatterns in urls.py.
I am trying to run my Django Application without Django admin panel because I don't need it right now but getting an exception value:

Put 'django.contrib.admin' in your INSTALLED_APPS setting in order to
  use the admin application.

Could I ran my application without django.contrib.admin ? Even if go my localhost:8000 it is showing you need to add django.contrib.admin in your installed_apps?
