Python manage.py runserver doesn't work on a project (Django)

Question

So I made my own project it worked with python manage.py runserver but when I tried with a new project, it's a challenge project and the challenge is to improve the django app. I use Python 3.8.1 (64-bit) and when I write python manage.py runserver on Admin Powershell it gives me this error:

ImportError: cannot import name 'python_2_unicode_compatible' from 'django.utils.encoding' (C:\Users\thatp\AppData\Local\Programs\Python\Python38-32\lib\site-packages\django\utils\encoding.py)

So if someone could help me that would be awesome.

The error are in your model, see bellow:

from django.utils.encoding import python_2_unicode_compatible
ImportError: cannot import name 'python_2_unicode_compatible' from 'django.utils.encoding' (C:\Users\thatp\AppData\Local\Programs\Python\Python38-32\lib\site-packages\django\utils\encoding.py

it only work on Django>=1.5, see here: https://stackoverflow.com/a/20741848/9710734
