No module named 'admin_ordering' even after pip install admin_ordering in venv and it shows in /venv/lib/

ok my settings INSTALLED_APPS looks like this

INSTALLED_APPS = [
    'correlator.apps.CorrelatorConfig',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'admin_ordering', 
]

After installing with pip with venv activated

pip intall admin_ordering

I see in venv/admin_ordering

in my models.py

    import datetime
from flag.models import Flag
from django.db import models
from django.utils import timezone
from django.contrib.contenttypes.fields import GenericRelation
from django.utils.translation import gettext_lazy as _

what step am I missing?
