title: Problem while using mypy with my django project
body: <p>I have implemented mypy in my django rest framework but  I am getting errors <code>ModuleNotFoundError: No module named 'config'</code> while running mypy.Is there any wrong with my <code>django_settings_module</code> in my mypy.ini file ?</p>
  
  <p>I used to run my project with the command <code>python manage.py runserver --settings=config.settings.development</code> which was working fine but while configuring this setting in the mypy it is giving me error. What I might be doing wrong ?</p>
  
  <p>Any help would be appreciated.</p>
