WARNING:tensorflow: The following Variables were used a Lambda layer's call (lambda), but are not present in its tracked objects: <tf.Variable 'attention_sequence_pooling_layer/local_activation_unit/kernel:0' shape=(16, 1) dtype=float32> <tf.Variable 'attention_sequence_pooling_layer/local_activation_unit/bias:0' shape=(1,) dtype=float32> It is possible that this is intended behavior, but it is more likely an omission. This is a strong indication that this layer should be formulated as a subclassed Layer rather than a Lambda layer.
