ModuleNotFoundError: нет модуля с именем «To_do.todos» - DJANGO

Итак, я только начал изучать django, и я учился из этого видео на YouTube: https://www.youtube.com/watch?v=Nnoxz9JGdLU

Итак, вот моя карта каталога: 

To_do
+To_do
 +_pycache_
 +_init_.py
 +asgi.py
 +settings.py
 +urls.py
 +wsgi.py 
+todos
 +_pycache_
 +migrations
 +_init_.py
 +admin.py
 +apps.py
 +models.py
 +tests.py
 +urls.py
 +views.py
+db.sqlite3
+manage.py

код To_do / To_do / urls.py 

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('todos/', include('todos.urls'))
]

код To_do / todos / urls.py 

from django.urls import path
from . import views
urlpatterns =[
    path('list/',views.list_todo_items)
]

код To_do / todos / view.py 

from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.


def list_todo_items(request):
    return HttpResponse('from list_todo_items')

Мой выпуск:

После использования вышеуказанных кодов с перенаправлениями, я явно где-то напутал, как в "основном" файле urls.py в каталоге проекта, когда я запускаю свой сервер, я получаю сообщение об ошибке: 

$ python3 manage.py runserver

ModuleNotFoundError: No module named 'To_do.todos'

Очевидно, что он не может найти файл "urls.py" в папке "todos", упомянутой в "urls" .py "в папке" To_do ".

согласно ошибке path('todos/', include('To_do.todos.urls')) следует изменить на 

path('todos/', include('todos.urls'))

Проверьте, добавлено ли приложение todos в список установленных приложений в файле settings.py 

INSTALLED_APPS = [
    ...
    'todos.apps.TodosConfig'
]

, остановите сервер ctrl + c, затем снова запустите сервер python manage.py runserver

...
