Unable to save model with h5 format

[johnloh47]

Hi Guys
Need helps/suggestions/advice in saving NLP model in h5 format.

Keep having this error.
"NotImplementedError: Save or restore weights that is not an instance of tf.Variable is not supported in h5, use save_format='tf' instead. Received a model or layer TextVectorization with weights [<keras.layers.preprocessing.index_lookup.VocabWeightHandler object at 0x7b2491497670>]"

Appreciate your helps

Hi @johnloh47 ,

Is there a specific reason you'd need to save in .h5?

Have you tried the other formats such as SavedModel or .keras?

Perhaps this discussion answer will help more: #412 (comment)

You can also export the TextVectorization layer as part of the model if you need: https://www.tensorflow.org/tutorials/keras/text_classification#export_the_model

Hi Daniel, thanks for your reply. Since Tensorflow developer certificate requires model to save as .h5 format, therefore, I am exploring ways to see what other code can be used so as to save the model as h5 format. I shall try out your recommendation. Thanks once again.
