I cannot open the admin site, an error appears:

Trying to enter in the site http://127.0.0.1:8000/admin/ I get this error:

I have already created db with mysql3 and have migrate too.
Thanks for your help!
Edit:
After I changed MIDDLEWARE_CLASSES for just MIDDLEWARE got this error after running the command python manage.py runserver:

UPDATE
I had to comment this line in MIDDLEWARE, inside settings.py:
'django.contrib.auth.middleware.SessionAuthenticationMiddleware'
and now everything works fine! THX!
回答1:
Your settings file was created using django 1.9. You are runnig django 2.0
Django 2.0 changed the middleware setting.
To activate a middleware component, add it to the MIDDLEWARE list in your Django settings.
Change
MIDDLEWARE_CLASSES = [...]
to
MIDDLEWARE = [...]
