Django wrapping modules in a folder?

Question

Django

Good day! I decided to clean up and structure the code a bit. It was decided to create an apps park, where I would store all my applications, so that there would be no mixing with templates and static, etc. But after modifications I get an error:

ImportError at /
No module named 'cart'
Request Method:	GET
Request URL:	http://89.223.28.112/
Django Version:	1.10.5
Exception Type:	ImportError
Exception Value:	
No module named 'cart'
Exception Location:	/home/dikiigr/posuda_shop/env/lib/python3.5/importlib/__init__.py in import_module, line 126
Python Executable:	/home/dikiigr/posuda_shop/env/bin/python3
Python Version:	3.5.2
Python Path:	
['/home/dikiigr/posuda_shop/engine',
 '/home/dikiigr/posuda_shop/env/bin',
 '/home/dikiigr/posuda_shop/env/lib/python35.zip',
 '/home/dikiigr/posuda_shop/env/lib/python3.5',
 '/home/dikiigr/posuda_shop/env/lib/python3.5/plat-x86_64-linux-gnu',
 '/home/dikiigr/posuda_shop/env/lib/python3.5/lib-dynload',
 '/usr/lib/python3.5',
 '/usr/lib/python3.5/plat-x86_64-linux-gnu',
 '/home/dikiigr/posuda_shop/env/lib/python3.5/site-packages']

But I can’t figure out what is the reason for such an action:
urls.py configured it seems to be correct:

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^attributes/', include('apps.attributes.urls', namespace='attributes')),
    url(r'^cart/', include('apps.cart.urls', namespace='cart')),
    url(r'^menu/', include('apps.menu.urls', namespace='menu')),
    url(r'^orders/', include('apps.orders.urls', namespace='orders')),
    url(r'^account/', include('apps.accounts.urls', namespace='accounts')),
    url(r'^pages/', include('apps.pages.url', namespace='pages')),
    url(r'^redactor/', include('redactor.urls')),
    url(r'^', include('apps.products.urls', namespace='products')),
]

Installed applications also seem to be correct:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'redactor',
    'apps.menu',
    'apps.products',
    'apps.cart',
    'apps.orders',
    'apps.accounts',
    'apps.attributes',
    'apps.pages'
]

The new structure is as follows:

That is, the __init__.py file is located in the root of the apps folder.
Who has any idea about this?

Problem solved! Did not set the path in the list of context processes
