如何防止Google Colab断开连接? [英] How to prevent Google Colab from disconnecting?

问题描述

问:是否可以通过编程方式阻止 Google Colab 超时断开连接?

Q: Is there any way to programmatically prevent Google Colab from disconnecting on a timeout?

以下内容描述了导致笔记本计算机自动断开连接的情况:

The following describes the conditions causing a notebook to automatically disconnect:

Google Colab笔记本的空闲超时为90分钟，绝对超时为12小时.这意味着，如果用户在超过90分钟的时间内未与其Google Colab笔记本进行互动，则其实例将自动终止.另外，Colab实例的最长生存期为12小时.

自然，我们希望自动将实例中的最大值从中挤出，而无需手动与不断.在这里，我假设常见的系统要求:

Naturally, we want to automatically squeeze the maximum out of the instance, without having to manually interact with it constantly. Here I will assume commonly seen system requirements:

• Ubuntu 18 LTS/Windows 10/Mac操作系统
• 对于基于Linux的系统，请使用流行的DE，例如Gnome 3或Unity
• Firefox或Chromium浏览器

我应该在这里指出，这种行为不违反 Google Colab的条款使用，尽管根据他们的常见问题解答(简称:从道德上讲，如果您真的不需要用尽所有GPU，那是不可行的.

I should point out here that such behavior does not violate Google Colab's Terms of Use, although it is not encouraged according to their FAQ (in short: morally it is not okay to use up all of the GPUs if you don't really need it).

我当前的解决方案非常愚蠢:

My current solution is very dumb:

• 首先，我关闭屏幕保护程序，因此屏幕始终保持打开状态.
• 我有一个Arduino开发板，所以我只是将它变成了橡胶ducky usb 并使其在我睡觉时模拟原始用户交互(只是因为我手头有其他用例).

• First, I turn the screensaver off, so my sreen is always on.
• I have an Arduino board, so I just turned it into a rubber ducky usb and make it emulate primitive user interaction while I sleep (just because I have it at hand for other use-cases).

还有更好的方法吗?

推荐答案

设置JavaScript间隔，每60秒单击一次connect按钮. 使用Ctrl + Shift + I打开开发人员设置(在您的Web浏览器中)，然后单击控制台选项卡，然后在控制台提示符下键入此设置. (对于Mac，请按Option + Command + I)

Set a javascript interval to click on the connect button every 60 seconds. Open developer-settings (in your web-browser) with Ctrl+Shift+I then click on console tab and type this on the console prompt. (for mac press Option+Command+I)

function ConnectButton(){
    console.log("Connect pushed"); 
    document.querySelector("#top-toolbar > colab-connect-button").shadowRoot.querySelector("#connect").click() 
}
setInterval(ConnectButton,60000);
