ValueError: Unknown layer:layers when I load the model，how can I fix it?

[InterestingApple]

Code(I put it in a separate file demo.py then run it): self.model = tf.keras.models.load_model(self.bundle_dir + '/models/SiameseLSTM.h5', custom_objects={'ManDist': ManDist}) self.model.summary() x = Sequential() x.add(self.model.get_layer('lstm')) self.intermediate_model = x
