NoReverseMatch at /admin/ error after upgrading Django

After I upgraded my Django project from 1.8 to 2.0, I try to log into the admin page, and receive this error message. I am able to see the login page, other links of the admin like "http://159.203.172.178/admin/QI/page/", but I can't see the first page only.

I definitely included too many code here because I really don't now where the problem is. Great thanks beforehand.

urls.py for admin:

from django.conf.urls import *
from django.contrib import admin
from django.contrib.admin.views.decorators import staff_member_required
from . import views
from django.urls import path,re_path,reverse,include

app_name="QI"

urlpatterns = [
path('admin/', admin.site.urls),
]


settings.py:

import os
from .settings_secret import *

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

STATIC_URL = '/static/'

STATIC_ROOT = os.path.join(BASE_DIR, 'static')
