Anyone managed to get this to work with saved model?

[connormeaton]

@veqtor I was not able to save the model until I wrote my own get_config.py function in the BertLayer class. Adding this code to the class made it run for me:

'''

def get_config(self):

    config = super(BertLayer, self).get_config().copy()
    config.update({
        'n_fine_tune_layers': self.n_fine_tune_layers,
        # 'trainable': self.trainable,
        # 'output_size': self.output_size,
        'pooling': self.pooling,
        'bert_path': self.bert_path,
    })

    return config

'''

Did you try to run the following code instead?

tf.keras.models.save_model( model, 'model', overwrite=True, include_optimizer=True )

I can't load the model:
model.save('/Documents/BERT/Sentiment_Classification_model_smallsiwetest.h5', overwrite=True, include_optimizer=True )

new_model = keras.models.load_model('Sentiment_Classification_model_smallsiwetest.h5')
Traceback (most recent call last):

@JiahuiSophieHU have you tried instantiating the BertLayer class and then including it as a custom_object argument?

new_model = keras.models.load_model('Sentiment_Classification_model_smallsiwetest.h5',
                                     custom_objects={'BertLayer': BertLayer})

I am facing a similar situation, not being able to load the saved model.

@smfullman tried this, but I am getting an error saying 'Shapes (768,) and (512, 768) are incompatible'.

@devinharia I am facing the same problem. Did you get the solution?
