如何防止Schedule阻塞主线程？

Question

我有一个程序，使用Python的Schedule包启动该程序后，该程序会在特定时间点拍摄网络摄像头图像。我的问题是，当我在另一个类中调用该类时，它将阻塞主线程。我试图在另一个构建Tkinter UI的程序中调用“ webcamPic”。但是，调用webcamPic时不会构建UI。我目前正在使用“ schedule_run_pending（）”运行时间表。我知道我应该使用run_continously（），但由于它不是标准Schedule库的一部分，所以我不知道如何调用该库或为此导入什么库。我当前的代码如下。除主要功能外，大多数都应该无关紧要。有人可以告诉我如何在另一个类中调用webcamPic而不阻塞主线程。
