already use model.save(). not use the load weight. the question is : self.b1 = BatchNormalization(), in my code, the BatchNormalization(), do not take any parameter, why Layer 'batch_normalization_20' expected 4 variables?

Sent by you: already use model.save(). not use the load weight. the question is : self.b1 = BatchNormalization(), in my code, the BatchNormalization(), do not take any parameter, why Layer 'batch_normalization_20' expected 4 variables?

change to 2.15.0 , it is ok. but a lot of change on
