tf.scalar_mul()

tf.scalar_mul(scalar, x)

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.

Args:

• scalar: A 0-D scalar Tensor. Must have known shape.
• x: A Tensor or IndexedSlices to be scaled.

Returns:

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

Raises:

• ValueError: if scalar is not a 0-D scalar.
