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. cl|d}tdt|D] }|||z } |t|z S)Nr)rangelen)selfinputsoutputis ]/var/www/html/engine/venv/lib/python3.12/site-packages/tf_keras/src/layers/merging/average.py_merge_functionzAverage._merge_function6sBq#f+& A fQi F F ##N)__name__ __module__ __qualname____doc__rrrrrs 8$rrzkeras.layers.averagec $tdi||S)aFunctional interface to the `tf.keras.layers.Average` layer.
