tf.scalar_mul

tf.math.scalar_mul(
    scalar, x, name=None
)

This is a special case of tf.math.multiply, where the first value must be a scalar. Unlike the general form of tf.math.multiply, this is operation is guaranteed to be efficient for tf.IndexedSlices.

x = tf.reshape(tf.range(30, dtype=tf.float32), [10, 3])
with tf.GradientTape() as g:
  g.watch(x)
  y = tf.gather(x, [1, 2])  # IndexedSlices
  z = tf.math.scalar_mul(10.0, y)

Args
`scalar`	A 0-D scalar `Tensor`. Must have known shape.
`x`	A `Tensor` or `IndexedSlices` to be scaled.
`name`	A name for the operation (optional).

Returns
`scalar * x` of the same type (`Tensor` or `IndexedSlices`) as `x`.

Raises
`ValueError`	if scalar is not a 0-D `scalar`.
