大牛时代配资Adds all input tensors element-wise.

Aliases:

  • tf.add_n
  • tf.compat.v1.add_n
  • tf.compat.v1.math.add_n
  • tf.compat.v2.add_n
  • tf.compat.v2.math.add_n
tf.math.add_n(
    inputs,
    name=None
)

Converts IndexedSlices大牛时代配资 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 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]]

Args:

  • inputs: A list of tf.Tensor or tf.IndexedSlices objects, each with same shape and type.
  • name: A name for the operation (optional).

Returns:

A Tensor of same shape and type as the elements of inputs.

Raises:

  • ValueError: If inputs don't all have same shape and dtype or the shape cannot be inferred.
