ModuleNotFoundError: No module named 'django_filters' when django-filter is installed

when I try to start my django app by running python manage.py runserver I get the error ModuleNotFoundError: No module named 'django_filters' however I have installed django-filter using pip install django-filterand added 'django_filters' to my INSTALLED_APPS in settings.py as the documentation says. So I'm having a hard time figuring out what's causing this issue. I appreciate any help.

Here is my INSTALLED_APPS

INSTALLED_APPS = [
    'rest_framework',
    'corsheaders',
    'students.apps.StudentsConfig',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django_filters',
    'crispy_forms',
]

and these are the packages I have
