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

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.

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.
