Getting an error in my django application " ModuleNotFoundError: No module named 'django.wsgi'". I have this error. I am not able to fix it

Question

I am running a web application. It is working in my local development server without any error but when I deployed it to Heroku, it has to build successfully. When I opened my application URL then it is giving application error. After viewing Heroku logs I found it is saying that ModuleNotFoundError.

here is the complete log of Heroku:

It is the complete log file. And here is my wsgi.py file:

"""
WSGI config for django_school project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see

application = get_wsgi_application()

How did you install django, and in what specific directory was it installed? — John Gordon, Apr 15 '20 at 05:15
This is probably due to configuration mismatch, i have similar experience with pythonanywhere, would suggest you recheck the path to wsgi.py specified on heroku. — Ansuman, Apr 15 '20 at 06:35
You don't usually need to change the `wsgi.py` in a Django project, so that probably isn't what the problem is. Please show your `Procfile`, and the layout of the files in your project (in particular where the `Procfile` and `wsgi.py` are located relative to each other). — Alasdair, Apr 15 '20 at 08:23
@JohnGordon I had installed Django in my venv using `pip install django`. — Rohit Singh, Apr 15 '20 at 09:21
@Alasdair I have added the layout of my project in the last of my question. Please have a look. — Rohit Singh, Apr 15 '20 at 09:28
Your wsgi file is in the `django_school` directory, so your `Procfile` should use `django_school.wsgi`, not `django.wsgi`. Change the `Procfile` to `web: gunicorn django_school.wsgi:application --python django_school`. The `--python django_school` part is required because your project isn't in the top level of the repo alongside the `Procfile`, see the related question for more info. — Alasdair, Apr 15 '20 at 10:03
