3 years ago Hi @damianospark, if you save a model with custom objects (like AdaBelief or some custom layers), you will also need to specify the custom objects when you are loading the model, so please try the following code to load the model:
model = tf.keras.models.load_model('./model.h5', custom_objects={'AdaBeliefOptimizer':AdaBeliefOptimizer})
Another option is to load the model without compiling, so you don't need to keep the code:
model = tf.keras.models.load_model('./model.h5', compile=False)
Dear all. I am excited to use Adabelief. And today I installed the package and tested it in my ML training successfully. When I load the model.h5 file to in different machine, the application keep showing error message as follows even if I installed the package whose command is 'pip3 install adabelief-tf==0.2.0' in both of machine whose OS is ubuntu 18.04 and Mac OSX.
It would be appreciated if you let me know if I am missing in your installation guide.
Best regards.
