Question

我无法得到DNNClassifier在训练时打印进度，即丢失和验证分数。据我所知，可以使用继承自BaseEstimator的config参数打印丢失，但是当我传递RunConfig对象时，分类器没有打印任何内容。

from tensorflow.contrib.learn.python.learn.estimators import run_config

config = run_config.RunConfig(verbose=1)
classifier = learn.DNNClassifier(hidden_units=[10, 20, 10],
                             n_classes=3,
                             config=config)
classifier.fit(X_train, y_train, steps=1000)

我错过了什么吗？我检查了RunConfig如何处理详细参数，看起来that it only cares if its greater than 1，它与文档不匹配：

详细：控制详细程度，可能的值： 0：算法和调试信息被静音。 1：培训师打印进度。 2：打印日志设备放置。

至于验证分数，我认为使用monitors.ValidationMonitor会很好，但是当尝试它时，分类器不会打印任何东西，尝试使用early_stopping_rounds时也没有任何反应。我在源代码中搜索文档或一些注释，但我找不到任何监视器。

在fit函数之前添加这些以显示进度：

import logging
logging.getLogger().setLevel(logging.INFO)

样品：

INFO:tensorflow:global_step/sec: 0
INFO:tensorflow:Training steps [0,1000000)
INFO:tensorflow:Step 1: loss = 10.5043
INFO:tensorflow:training step 100, loss = 10.45380 (0.223 sec/batch).
INFO:tensorflow:Step 101: loss = 10.5623
INFO:tensorflow:training step 200, loss = 10.46701 (0.220 sec/batch).
INFO:tensorflow:Step 201: loss = 10.3885
INFO:tensorflow:training step 300, loss = 10.36501 (0.232 sec/batch).
INFO:tensorflow:Step 301: loss = 10.3441
INFO:tensorflow:training step 400, loss = 10.44571 (0.220 sec/batch).
INFO:tensorflow:Step 401: loss = 10.396
INFO:tensorflow:global_step/sec: 3.95

在训练之前添加此行：

 <table>
<?php
 //database connent
    include 'anslutsqli.php'; 
//sql select day from events have now two dates in my db
$sql = "SELECT day FROM test";
$result = mysqli_query($con, $sql);

    //naming the sql dates var
    $sqldates = array();  
while($row=mysqli_fetch_array($result)){
array_push($sqldates, $row['day']);
} 
//setting first day
  $firstday = '1';

  $two = cal_days_in_month(CAL_GREGORIAN, 8, 2018); // 31
  //for loop to get all days in month( this makes the while loop run two times i have two dates in my db 3 and 4)
  for ($number = $firstday; $number <= $two; $number++)

  if (in_array($number, $sqldates)) {
    echo"<td width=50 bgcolor='#f44242'>$sqldates</td>";
  } else {
    echo"<td width=50 bgcolor='#1e8e8e'>$number</td>";
  }

?>
</table>

如何在tensorflow r0.9（skflow）中训练DNNC分类器时打印进度？
