tf.math.scalar_mul

Multiplies a scalar times a Tensor or IndexedSlices object.

Intended for use in gradient code which might deal with IndexedSlices objects, which are easy to multiply by a scalar but more expensive to multiply with arbitrary tensors.

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).

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

ValueError if scalar is not a 0-D scalar.
