IPython Notebook - 在Javascript中检测内核是否忙/闲 [英] IPython Notebook - Detect if Kernel is Busy/Idle in Javascript
问题描述
我目前正在尝试使用IPython笔记本进行交互式绘图。我遇到的一个问题是，当在javascript中通过IPython.notebook.kernel.execute方法执行Python代码时，我无法知道该段代码何时完成执行。是否有一种简单的方法可以检测内核是忙还是空闲，这样我就可以告诉Javascript闲置直到它完成？
I'm currently trying to get interactive plots working with IPython notebook. One of the issues I'm having is the fact that when executing Python code through the IPython.notebook.kernel.execute method in javascript I have no way of knowing when that piece of code has finished executing. Is there an easy way of detecting whether the kernel is busy/idle so that I can tell Javascript to idle until it's completed?
推荐答案
内核状态可能就是你要找的东西：
The Kernel status is probably what you are looking for:

你可以在IPython笔记本的kernel.js中找到一些额外的灵感（只搜索忙）：
You can find some additional inspiration in the kernel.js of the IPython notebook (just search for "busy"):
