url('blog/', include('blog.urls',namespace='blog')),

报错如下：

File "D:\Django_test\myblog\myblog\urls.py", line 7, in <module>

    url('blog/', include('blog.urls',namespace='blog')),    # 设置超链接

  File "D:\anaconda3\lib\site-packages\django\urls\conf.py", line 39, in include

    'Specifying a namespace in include() without providing an app_name '

django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead.

其中报错主要信息如第二行；希望能够得到回复，谢谢?
