Reading accuracy in Keras from the saved model
According to the official Keras website, you have to use:

keras.models.load_model(filepath)


Example:

model = load_model('my_model.h5')


This will load your saved H5 model to 'model' and then you can try:

model.evaluate(x,y)


To return the loss value &amp; metrics values for the model in test mode.
