django-admin-tools 0.8 after installation and configuration gives an error 404 when popitka login to the admin panel

I installed and configured the django-admin-tools 0.8 plugin according to the documentation. Django version 1.11.4. I do the project through virtualenv.

Settings in the file settings.py:

INSTALLED_APPS = [
    'admin_tools',
    'admin_tools.theming',
    'admin_tools.menu',
    'admin_tools.dashboard',
    'django.contrib.auth',
    'django.contrib.sites',
    'django.contrib.admin',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'atelierapp',
]

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        #'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
                'django.core.context_processors.request',
            ],
            'loaders': [
                'admin_tools.template_loaders.Loader',
            ]
        },
    },
]

File urls.py:

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

But when I want to go to the admin panel, an error appears:

404 File not found

Question: what is the problem? Thank you for your time.
