我不相信JavaScript解决方案还能继续工作。我在我的笔记本里写了:

    from IPython.display import display, HTML
    js = ('<script>function ConnectButton(){ '
           'console.log("Connect pushed"); '
           'document.querySelector("#connect").click()} '
           'setInterval(ConnectButton,3000);</script>')
    display(HTML(js))

当你第一次执行Run all(在JavaScript或Python代码开始之前)时，控制台显示:

Connected to
wss://colab.research.google.com/api/kernels/0e1ce105-0127-4758-90e48cf801ce01a3/channels?session_id=5d8...

然而，每次JavaScript运行时，你都会看到console.log部分，但点击部分只是给出:

Connect pushed

Uncaught TypeError: Cannot read property 'click' of null
 at ConnectButton (<anonymous>:1:92)

其他人建议按钮名称已更改为# coab -connect-button，但这也会产生相同的错误。

After the runtime is started, the button is changed to show RAM/DISK, and a drop down is presented. Clicking on the drop down creates a new <DIV class=goog menu...> that was not shown in the DOM previously, with 2 options "Connect to hosted runtime" and "Connect to local runtime". If the console window is open and showing elements, you can see this DIV appear when you click the dropdown element. Simply moving the mouse focus between the two options in the new window that appears adds additional elements to the DOM, as soon as the mouse looses focus, they are removed from the DOM completely, even without clicking.

只需在想要运行以防止数据丢失的单元格后运行下面的代码。

!python

另外，要退出此模式，请写入

exit()

更新(2021年7月)。

function ConnectButton(){ 
    console.log("Working"); 
    document.querySelector("#connect").click() 
}
setInterval(ConnectButton, 60000);

你也可以使用Python来按方向键。我也在下面的代码中添加了一点随机性。

from pyautogui import press, typewrite, hotkey
import time
from random import shuffle

array = ["left", "right", "up", "down"]

while True:
    shuffle(array)
    time.sleep(10)
    press(array[0])
    press(array[1])
    press(array[2])
    press(array[3])

好吧，我找到了一个很好的解决办法，可以摆脱

活动会话

自动弹出。我们需要两个函数，

与前面的步骤相同。逐个检查>控制台>粘贴功能

1

function clickConnect() {
    try {
         document.querySelector("#top-toolbar > colab-connect-button").shadowRoot.querySelector("#connect").click();
        // this also works, if above one doesn't work, comment it and uncomment below one
        //document.querySelector("colab-connect-button").shadowRoot.getElementById('connect').click();
        setTimeout(clickDismiss, 500);
        console.log("Keeping Colab Alive!");    
    } catch (error) {
        console.log(error);
    }
}

2

function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms));
}

3

async function clickDismiss() {
    
    try {   
        
        // click manage session button
        document.querySelector("colab-usage-display").shadowRoot.querySelector("paper-button").click();
    
        } catch (error) {
        console.log(error);
    }
    
        try {
            // leave from manage session window
            await sleep(1000);
            document.querySelector('colab-sessions-dialog').shadowRoot.querySelector('.dismiss').click();
                } catch (error) {
        console.log(error);
    }
    
        try {   
            // click close button
            await sleep(1000);
            document.querySelector("paper-tab").querySelector("paper-icon-button").shadowRoot.getElementById('icon').click();
                } catch (error) {
        console.log(error);
    }
    
}

4

setInterval(ClickConnect, 60000);

编辑:

所以，如果你不喜欢手动做所有这些事情，有一种方法来自动化所有这些!

Way_1。使用这个Chrome扩展和完成

or

Way_2。

使用page -机械手扩展 点击它，然后点击添加Java脚本按钮> +新建+ >文件名 文件名是ColabAlive > Make 活跃网站= colab.research.google.com 匹配页面=递归 然后使用下面的代码，

// 1 function clickConnect() { try { document.querySelector("#top-toolbar > colab-connect-button").shadowRoot.querySelector("#connect").click(); // this also works, if above one doesn't work, comment it and uncomment below one //document.querySelector("colab-connect-button").shadowRoot.getElementById('connect').click(); setTimeout(clickDismiss, 500); console.log("Keeping Colab Alive!"); } catch (error) { console.log(error); } } //2 function sleep(ms) { return new Promise(resolve => setTimeout(resolve, ms)); } //3 async function clickDismiss() { try { // click manage session button document.querySelector("colab-usage-display").shadowRoot.querySelector("paper-button").click(); } catch (error) { console.log(error); } try { // leave from manage session window await sleep(1000); document.querySelector('colab-sessions-dialog').shadowRoot.querySelector('.dismiss').click(); } catch (error) { console.log(error); } try { // click close button await sleep(1000); document.querySelector("paper-tab").querySelector("paper-icon-button").shadowRoot.getElementById('icon').click(); } catch (error) { console.log(error); } } //4 setInterval(clickConnect, 60000);

单击“活动”，然后重新加载> done

这要归功于Oshayr, Albert Einstein和每个在这里发表他们的解决方案的人。

这对我来说很管用:

在控制台中运行以下代码，它将阻止您断开连接。

按Ctrl + Shift + I打开检查器视图。然后去控制台。

function ClickConnect(){
    console.log("Working");
    document.querySelector("colab-toolbar-button#connect").click()
}
setInterval(ClickConnect,60000)
