Defined in tensorflow/python/ops/math_ops.py.

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.
  • 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.
