Django migration error (urls.w005) URL namespace admin isnt unique You may not be able to reverse all URLs

Record common errors

WARNINGS:
?: (urls.W005) URL namespace 'admin' isn't unique. You may not be able to reverse all URLs in this namespace

The problem is that I define a sub route in the route

from django.contrib import admin
from django.urls import path,include
urlpatterns = [
path('admin/', admin.site.urls),
path('api/', include('RBACapp.urls')),
]

  For sub routes admin Just pour it out
