ImportError: попытка относительного импорта без известного родительского пакета при запуске main.py

Question

Я использую Django 3.0 для своего проекта и хочу сделать простую страницу регистрации. Моя регистрационная информация не отображается на странице базы данных администратора. python manage.py runserver не вызывает ошибок, но admin.py и views.py имеют ошибки импорта. Я также использую тот же фрагмент кода. Вот несколько фрагментов моих admin.py, views.py, models.py и settings.py.

ошибка
