使用pyqt5在python上得到一些错误

Question

我在两个qt中使用类创建了一个文件。当我运行这两个文件分开时，它工作得很好。(主菜单)和(查找器)，但当我调用文件时，我得到错误。我试图调用另一个文件，如打印hello，它做——导入——子例程。接下来，我尝试异常，当它仍然有这两个文件在一起自动失败，没有消息。我知道两者都有相同的类由于QT设计师，但我不知道该怎么做。他们都讨厌对方。

文件合并

文件主菜单从PyQt5导入QtCore, QtGui, QtWidgets从PyQt5。QtGui导入QPixmap

如果有人找到一个修复，这将是非常有帮助的，因为没有类似的在线。
