Setting the Django Debug toolbar: TypeError: __init __ () takes 1 positional argument, but 2 are given

Question

Django 1.10

Django-debugging tools == 1.5

New project (I just installed Django). Trying to install Django Debug toolbar.

Documentation: https://django-debug-toolbar.readthedocs.io/en/stable/installation.html#prerequisites

According to the documentation, this version of the django-debug toolbar is compatible with Django 1.10.

Could you help me understand what I did wrong.

settings.py

# { django-debug-toolbar
DEBUG_TOOLBAR_PATCH_SETTINGS = False
INTERNAL_IPS = ['127.0.0.1', ]
if DEBUG:
    MIDDLEWARE += ['debug_toolbar.middleware.DebugToolbarMiddleware',]
    INSTALLED_APPS += ['debug_toolbar',]
# } django-debug-toolbar

urls.py

from django.conf import settings
from django.conf.urls import include
if settings.DEBUG:
    import debug_toolbar
    urlpatterns += [
        url(r'^__debug__/', include(debug_toolbar.urls)),
    ]
