It takes as input a list of tensors of size 2, both of the same shape, and returns a single tensor, (inputs[0] - inputs[1]), also of the same shape. Examples: ```python import tf_keras.src as keras input1 = keras.layers.Input(shape=(16,)) x1 = keras.layers.Dense(8, activation='relu')(input1) input2 = keras.layers.Input(shape=(32,)) x2 = keras.layers.Dense(8, activation='relu')(input2) # Equivalent to subtracted = keras.layers.subtract([x1, x2]) subtracted = keras.layers.Subtract()([x1, x2]) out = keras.layers.Dense(4)(subtracted) model = keras.models.Model(inputs=[input1, input2], outputs=out) ``` c\t||t|dk7rtd|y)NzOA `Subtract` layer should be called on exactly 2 inputs.
