估计器训练期间无评估且无记录

如何解决估计器训练期间无评估且无记录

我正在训练玩具数据集上的DNNLinearCombinedClassifier。在训练期间，训练损失不会显示在标准输出上。实际上，只有警告显示在stderr上。此外，评估仅在训练结束时执行一次，而不是每30秒执行一次。我正在运行以下代码：

这仅在stderr上返回警告，而在stdout上不返回任何警告。训练损失正确记录在tf.summary中。我可以在Tensorboard上可视化它。但是，在步骤20000，评估仅执行一次，并且仅返回准确性。计算持续约3分钟。因此，我希望在Tensorboard中看到5到6个评估点，而不是一个。

在训练期间，我应该如何在stdout上显示一些日志信息（至少是训练损失）？ 在培训期间，不仅在结束时，我如何进行评估？

非常感谢您对这个令人沮丧的情况的启迪。
