It takes as input a list of tensors, all of the same shape, and returns a single tensor (also of the same shape). Example: >>> x1 = np.ones((2, 2)) >>> x2 = np.zeros((2, 2)) >>> y = tf.keras.layers.Average()([x1, x2]) >>> y.numpy().tolist() [[0.5, 0.5], [0.5, 0.5]] Usage in a functional model: >>> input1 = tf.keras.layers.Input(shape=(16,)) >>> x1 = tf.keras.layers.Dense(8, activation='relu')(input1) >>> input2 = tf.keras.layers.Input(shape=(32,)) >>> x2 = tf.keras.layers.Dense(8, activation='relu')(input2) >>> avg = tf.keras.layers.Average()([x1, x2]) >>> out = tf.keras.layers.Dense(4)(avg) >>> model = tf.keras.models.Model(inputs=[input1, input2], outputs=out) Raises: ValueError: If there is a shape mismatch between the inputs and the shapes cannot be broadcasted to match. cCs4|d}tdt|ƒƒD]}|||7}q |t|ƒS)Nré)ÚrangeÚlen)ÚselfÚinputsÚoutputÚi©r úa/home/www/facesmatcher.com/pyenv/lib/python3.10/site-packages/keras/src/layers/merging/average.pyÚ_merge_function6s zAverage._merge_functionN)Ú__name__Ú __module__Ú __qualname__Ú__doc__rr r r r rs rzkeras.layers.averagecKstdi|¤Ž|ƒS)aÓFunctional interface to the `tf.keras.layers.Average` layer.
