Question

Medical - servicelist.py - settings.py - urls.py - wsgi.py - clients/ - static/ - templates/ из этого

каталога я запускаю servicelist.py, в котором, в частности, имеется:
import django

sys.path.extend(['/home/RSFmed/medical_env/medical/medical', ])
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "medical.settings")
django.setup()

from catalog.models import ServiceList
from catalog.models import Service

from clients import views

Так вот, программа запускается и выдает:
Traceback (most recent call last):

ModuleNotFoundError: No module named 'medical'

Чего не хватает в этом супе? О каком модуле medical идет речь? Если поможете, помогите разобраться.
