Python-帮助（'模块'）意外的行为

Question

我一直在玩使用PySide的QT和python。我刚刚完成了基本的tutorials之一。我关闭了python并重新启动了另一个会话，现在每当我尝试使用help('modules')列出模块时，按钮教程都会运行。如果我关闭窗口python崩溃。错误消息的顶部是

我最近的操作是安装'PIP'并下载一些软件包。有谁知道是什么原因造成的或如何解决？

我注意到，改变目录意味着PySide教程将无法运行。现在它像以前一样打印出可用的模块，但它也从任何目录加载一个TK窗口。

我在开始出现此问题之前安装了PyOpenGL。卸载它的问题也消失了
