嗨，我在进行迁移或使用python manage.py runserver命令时遇到此错误。
警告：
?:（urls.W005）URL名称空间“供应商”不是唯一的。您可能无法撤消此命名空间中的所有URL
?:（urls.W005）URL名称空间“老师”不是唯一的。您可能无法撤消此命名空间中的所有URL
这是我的应用程序目录（教室）中的urls.py：

在搜索google时，我发现这是因为我的网址之一重复了，但我不知道是哪一个。我尝试替换最后一行中的名称空间：
path('quiz/<int:quiz_pk>/question/<int:question_pk>/delete/', teachers.QuestionDeleteView.as_view(), name='question_delete'), ],'classroom'), namespace='teachers')), ]
但是它给我一个新的错误，无论我用什么名字，即使是胡言乱语。发生了什么事？
