python - google ai 平台上的超参数调优错误：“replica master 0 exited with a non-zero status of 1”

Question

在谷歌云 AI 平台上训练深度学习模型时，使用超参数调整（我的超参数配置信息在 YAML 文件中），我收到此错误：

Hyperparameter Tuning Trial #2 Failed before any other successful trials were completed. 
The failed trial had parameters: batch_size=11, learning_rate=3.527059074944887e-05, .
The trial's error message was: The replica master 0 exited with a non-zero status of 1

由于错误消息有点笼统，我很难理解问题可能出在哪里。

我的 YAML 配置文件：

trainingInput:
  hyperparameters:
    goal: MINIMIZE
    maxTrials: 2
    maxParallelTrials: 2
    hyperparameterMetricTag: loss
    enableTrialEarlyStopping: FALSE
    params:
      - parameterName: batch_size
        type: INTEGER
        minValue: 8
        maxValue: 16
        scaleType: UNIT_LINEAR_SCALE
      - parameterName: learning_rate
        type: DOUBLE
        minValue: 0.00001
        maxValue: 0.0001
        scaleType: UNIT_LINEAR_SCALE
