window.show（）“分段错误（核心已转储）”

时间：2019-12-26 11:20:59

标签： python opencv widget pyqt5 python-3.6

当我第一次运行并且我的程序正常运行时，我的程序出现了问题，但是我关闭并再次尝试运行，但出现了一些错误，例如“分段错误（内核已转储）”。 然后我尝试使用以下命令运行：python -Xfaulthandler test.py并获得错误。

  

我正在使用   库本图16.04   Python3.6   PyQt5   Opencv 4.1.1

。

  

致命的Python错误：分段错误   当前线程0x00007fcd3591b740（最新呼叫优先）：     文件“ test.py”，位于第158行   分段错误（核心已转储）

这行有问题：

window.show()

为什么此行出错？，您可以向我解释一下吗，请问该如何解决？

我的完整程序：
