python - 帮助 ('modules' ) 崩溃？不确定如何解决

Question

我试图为 opencv 安装一个模块，并在我的 sites.py 文件之外的文件夹中添加了一个 opencv.pth 文件。我已经删除了它，没有任何变化。

当我尝试运行 help('modules') 时，出现以下错误:

Please wait a moment while I gather a list of all available modules...

什么给了？!

发生这种情况是因为 help('modules') 导入了所有模块，这会导致执行大量未标记的代码。除了报告导致此问题的每个包(在本例中为 opencv)中的错误并等待他们修复它之外，您无能为力。
