Adds all input tensors element-wise.

tf.math.add_n(
    inputs, name=None
)

Converts IndexedSlices objects into dense tensors prior to adding.

tf.math.add_n performs the same operation as tf.math.accumulate_n, but it waits for all of its inputs to be ready before beginning to sum. This buffering can result in higher memory consumption when inputs are ready at different times, since the minimum temporary storage required is proportional to the input size rather than the output size.

This op does not broadcast its inputs. If you need broadcasting, use tf.math.add (or the + operator) instead.

For example:

a = tf.constant([[3, 5], [4, 8]])
b = tf.constant([[1, 6], [2, 9]])
tf.math.add_n([a, b, a])  # [[7, 16], [10, 25]]
