Start at src/Microsoft.ML.ModelBuilder.AutoMLService/Experiments/LocalImageClassificationExperiment.cs line 114 and trace the call through AutoMLExperiment.RunAsync to src/Microsoft.ML.ModelBuilder.AutoMLService/AutoMLEngineService/AutoMLEngine.cs line 178. Reproduce the image-classification training failure and determine why no completed trial has a finite metric. Done means training completes with at least one successful trial and a finite metric.
