tf.math.scalar_mul
Multiplies a scalar times a Tensor or IndexedSlices object.
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. |
