我使用宏程序定期点击RAM/Disk按钮来整晚训练模型。诀窍是配置一个宏程序，点击Ram/Disk Colab工具栏按钮两次，两次点击之间的间隔很短，这样即使运行时断开连接，它也会重新连接回来。(第一次点击用于关闭对话框，第二次点击用于重新连接)。 然而，你还是得整晚打开笔记本电脑，可能还得固定Colab标签。

对我来说，以下是一些例子:

document.querySelector(“#连接”).click()或 document.querySelector(“colab-toolbar-button #连接”).click()或 document.querySelector(“colab-connect-button”).click ()

我们失误了。

我必须调整它们以适应以下情况:

版本1:

function ClickConnect(){
  console.log("Connnect Clicked - Start"); 
  document.querySelector("#top-toolbar > colab-connect-button").shadowRoot.querySelector("#connect").click();
  console.log("Connnect Clicked - End"); 
};
setInterval(ClickConnect, 60000)

版本2: 如果你想停止这个函数，下面是新代码:

var startClickConnect = function startClickConnect(){
    var clickConnect = function clickConnect(){
        console.log("Connnect Clicked - Start");
        document.querySelector("#top-toolbar > colab-connect-button").shadowRoot.querySelector("#connect").click();
        console.log("Connnect Clicked - End"); 
    };

    var intervalId = setInterval(clickConnect, 60000);

    var stopClickConnectHandler = function stopClickConnect() {
        console.log("Connnect Clicked Stopped - Start");
        clearInterval(intervalId);
        console.log("Connnect Clicked Stopped - End");
    };

    return stopClickConnectHandler;
};

var stopClickConnect = startClickConnect();

为了停止，调用:

stopClickConnect();

也许以前的许多解决方案不再有效。例如，下面的代码继续在Colab中创建新的代码单元格，但仍然有效。毫无疑问，创建一堆代码单元是不方便的。如果在运行的几个小时内创建了太多的代码单元，并且没有足够的RAM，浏览器可能会冻结。

这将重复创建代码单元格-

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

但我发现下面的代码是工作的，它不会引起任何问题。在Colab notebook选项卡中，同时单击Ctrl + Shift + i键并将以下代码粘贴到控制台中。120000个间隔就足够了。

function ClickConnect(){
console.log("Working"); 
document.querySelector("colab-toolbar-button#connect").click() 
}setInterval(ClickConnect,120000)

我在2020年11月在firefox中测试了这段代码。它也会在铬上工作。

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.

使用Python和Selenium:

from selenium.webdriver.common.keys import Keys
from selenium import webdriver
import time

driver = webdriver.Chrome('/usr/lib/chromium-browser/chromedriver')

notebook_url = ''
driver.get(notebook_url)

# run all cells
driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + Keys.F9)
time.sleep(5)

# click to stay connected
start_time = time.time()
current_time = time.time()
max_time = 11*59*60 #12hours

while (current_time - start_time) < max_time:
    webdriver.ActionChains(driver).send_keys(Keys.ESCAPE).perform()
    driver.find_element_by_xpath('//*[@id="top-toolbar"]/colab-connect-button').click()
    time.sleep(30)
    current_time = time.time()

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。
