What should I do to successfully import my database to heroku and get it working? Please let me know if I need to add any of my files on here.
This is my directory layout in visual studio code -
Django directory

When I run my Django project developed on Windows on Ubuntu it gives errors as below, even after creating virtualenv and configured properly

Here is the errors
I have installed and created virtualenv as same like the one on Windows and replaced it on Ubuntu with that new one. I could activate the virtual but when I do python3 manage.py runserver it gives error as like below. If someone help, it will be grateful.

ModuleNotFoundError: No module named 'djangoproject'
It should just run with no error and run the server.

Your Django file structure should look like this:
djangoproject/
manage.py
djangoproject/
__init__.py
settings.py
urls.py
wsgi.py
__init__.py tells Python to treat the parent directory as a module.
ModuleNotFoundError: No module named 'djangoproject'
By rearranging the folder structure, you've stopped Python from treating that folder as a module. Manage.py needs that module to perform its operations.
