Autokeras: Save top 3 best models

[abdulsam]

I want to save not just one but the top 3 best performing models created by AutoKeras. I want to analyze the differences between them. How can I save them?

You can use AutoModel.tuner.get_best_models(3)

You can use AutoModel.tuner.get_best_models(3)

This will enlist the best 3 models. I want to save these models or export them. Is there any way to do this?

@abdulsam You can use a for loop to do so.

for index, model in enumerate(AutoModel.tuner.get_best_models(3)):
  model.save('model' + str(index) + '.h5')

@haifeng-jin While loading the saved models, it is giving a warning
WARNING:tensorflow:Error in loading the saved optimizer state. As a result, your model is starting with a freshly initialized optimizer.

I ignored this warning because I can train it again. But while using fit() method on the loaded model, it is showing this error:
ValueError: Shapes (None, 1) and (None, 10) are incompatible

I guess it is because of the label encoding? We do a one-hot encoding for the labels under the hood.
