positive¶

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

Returns the input Tensor as it is. This is used in Tensor.__pos__, applying the unary + operator to the tensor.

$$Out = +X$$

Parameters

• x (Tensor) – The input tensor. The tensor cannot be of type bool.

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

Returns

A tensor with the same shape and data type as the input tensor. The returned tensor

is the same.

Return type

Tensor

Examples

>>> import paddle
>>> x = paddle.to_tensor([-1, 0, 1])
>>> out = paddle.positive(x)
>>> print(out)
Tensor(shape=[3], dtype=int64, place=Place(cpu), stop_gradient=True,
[-1,  0,  1])
