AttributeError: 'History' object has no attribute 'save'

Question

source: tensorflow tutorials – Save and Load

I trained my model with EfficientNetB0 from tensorflow hub
It went well when fit.

# Fit EfficientNet model
efficientnet_history = efficientnet_model.fit(train_data,
                                              epochs=2,
                                              steps_per_epoch=len(train_data),
                                              validation_data=test_data,
                                              validation_steps=len(test_data),
                                              callbacks = [learning_rate_reduction, modelCheckpoint])

results:

Epoch 00002: saving model to training_1cp.ckpt

But why this model cannot be saved with efficientnet_history.save?
my code:

efficientnet_history.save("signlen_efficientnet_model.h5")

error:

Traceback (most recent call last):
  File "c:/Users/OOO/Desktop/Projects/SignLens/test/ASL_for_fun/asl_train.py", line 89, in <module>
    efficientnet_history.save("signlen_efficientnet_model.h5")
AttributeError: 'History' object has no attribute 'save'

How to save model correctly?
Or, is there another way to save model?

Answer 1

The reason you are getting this error is because you are calling save on a History object. You should call save on the model itself.
For example, change this:

efficientnet_history.save("signlen_efficientnet_model.h5")

To this:

efficientnet_model.save("signlen_efficientnet_model.h5")
