I am new to Django and I want to create some API with tastypie, but when I import ModelResource from tastypie.resource I face with error :/ I just do this:
from tastypie.resources import ModelResource
I get this error:

The current Django version is 3.2 . I try to install the latest version of Django (4.1.1) to fix the error but it doesn't work. The version of tastypie is 0.14.4. If it helps I use python version 3.9. Thanks
Problem solved :/ There was a problem with GDAL on my system and the Django version. I just run this command in my terminal:
brew link --overwrite gdal
and downgrade the Django version to 3.2 .
