超过最大执行时间

Question

这是我的代码：

1. 复制电子表格并将其转储到gdrive文件夹（复制数量取决于我的配置文件上的员工数量）。目前，我有800多名员工。
2. 复制后，gdrive文件夹中的每个电子表格都发布为html。 （我在这里使用了循环）
3. 获取每个电子表格的pubHTML链接，并将其放入我的配置文件中。

在第3步（获取pubHTML并将其放入配置文件中）时，我得到了超出的最大执行时间。

我的代码按预期工作。我想避免执行错误的最大限制。

    base_model = VGG16(include_top = False, input_shape=(32, 32, 3))
    base_model.layers.pop() 
    base_model.ouputs =[base_model.layers[-1].output]
    #last = base_model.outputs[0] model.add(base_model) 
    model.add(layers.ZeroPadding2D(padding=(1,1)))
    model.add(layers.Conv2D(filters=1024,
    kernel_size=(3,3),activation='relu'))
    model.add(layers.GlobalAveragePooling2D())
    model.add(layers.Dense(10,activation='softmax'))

只运行一次代码，不会超过最大执行时间错误。有什么建议吗？

下面的代码是根据我以前使用的代码修改的。这样的方法可以让您完全执行在execution time limit中无法完成的批处理。通过知道批处理中的一项操作需要多长时间，您可以在达到该限制之前在Properties中保存进度，并在programmatically create a trigger中保存进度以恢复处理。

您需要做一些事情才能使其正常工作：

1. 您需要修改我的getEmployees_()函数以从您的配置文件中准确地获取员工。
2. 正如我在评论中提到的那样，您需要重构代码，以便可以对单个员工执行复制。该代码应该放在我的replicateForEmployee_()函数中。
3. 运行determineTimes()函数以查看获取员工和文件复制所需的时间。
4. 在determineTimes()函数中插入replicate()的结果。

determineTimes()的输出将在“执行”页面（“视图”>“执行”）中可见。展开执行行，您将看到如图所示的持续时间。

/**
 * Get all of the employees in the sheet. Assumes row in the sheet is one employee. Adjust the range as needed.
 * @returns {Object[][]}
 */
function getEmployees_() {
  var source = SpreadsheetApp.openById("configfile--xxxx");
  var sheet = source.getSheetByName("Mastersheet");
  return sheet.getRange(1, 1, sheet.getLastRow(), sheet.getLastColumn()).getValues();
}

/**
 * Refactor your current code so that this function will replicate all necessary files for a single
 * employee. The function will be called for every single employee.
 * @param {Object[]} employee - The row representing the employee in your config file
 */
function replicateForEmployee_(employee) {
  // Execute your replication process for a SINGLE employee here
}

/**
 * Run this, and then examine your script executions (View > Executions) to see how long each
 * function takes. The resulting durations should replace the corresponding values in the replicate()
 * function (I would recommend rounding up, so 458 --> 500ms).
 */
function determineTimes() {
  console.time("timeToGetEmployees");
  var employees = getEmployees_(); // Get all of the employees
  console.timeEnd("timeToGetEmployees");

  console.time("replicationDuration");
  replicateForEmployee_(employees[0]); // Execute replication once
  console.timeEnd("replicationDuration");
}

/**
 * Replicates the files. When approaching the time limit, will save location and set a trigger to
 * continue from stopping point. Emails user upon completion.
 * @param {Boolean} isFromTrigger

 */
function replicate(isFromTrigger) {
  var employees = getEmployees(); // Get all of the employees
  var timeToGetEmployees = 1000; // Assume 1 second to execute getEmployees()
  var replicationDuration = 500; // Number of milliseconds it takes to execute replication for one employee.
  var maxExecutionTime = 360000 - timeToGetEmployees; // 6 mins - time already used to get employees

  var continueFrom = 0; // If first execution, will be zero. Otherwise, get the index to start from.
  if (isFromTrigger === true) {
    continueFrom = parseInt(PropertiesService.getScriptProperties().getProperty("continueFrom"), 10);
  }
  var lapsedTime = 0; // ESTIMATED amount of time that has lapsed since the replication started

  for (var i = continueFrom; i < employees.length; i++) {
    // Replicate files for the employee
    replicateForEmployee_(employees[i]);

    // Checks how much time you have left
    lapsedTime += replicationDuration;
    if (lapsedTime >= (maxExecutionTime - replicationDuration)) { // warn just before timing out
      PropertiesService.getScriptProperties().setProperty("continueFrom", i + 1); // save the last iterator value + 1
      createAfterTrigger("replicateFromTrigger", 60000); // Start again in one minute
      console.info("About to time out. Last iterator: " + i);
      return;
    }
  }

  deleteAllTriggers(); // Cleanup any lingering triggers
  PropertiesService.getScriptProperties().deleteProperty("continueFrom"); // Clean up properties

  // Send completion email
  MailApp.sendEmail(Session.getEffectiveUser().getEmail(), "Replication Complete", "");
}

/**

  replicate(true);

function createAfterTrigger(functionName, milliseconds) {
  ScriptApp.newTrigger(functionName)
