reciprocal

paddle. reciprocal ( x: Tensor, name: str | None = None, *, out: Tensor | None = None ) → Tensor [source]

Reciprocal Activation Operator.

\[\begin{split}out = \\frac{1}{x}\end{split}\]

Parameters

• x (Tensor) – Input of Reciprocal operator, an N-D Tensor, with data type float32, float64, float16, bfloat16, uint8, int8, int16, int32, int64.

• name (str|None, optional) – Name for the operation (optional, default is None). For more information, please refer to api_guide_Name.

• out (Tensor, optional) – The output Tensor. If set, the result will be stored in this Tensor. Default: None.

Returns

Tensor. Output of Reciprocal operator, a Tensor with shape same as input

(integer types are autocasted into float32).

Examples

>>> import paddle

>>> x = paddle.to_tensor([-0.4, -0.2, 0.1, 0.3])
>>> out = paddle.reciprocal(x)
>>> print(out)
Tensor(shape=[4], dtype=float32, place=Place(cpu), stop_gradient=True,
[-2.50000000, -5.        ,  10.       ,  3.33333325])
