sqrt¶

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

Sqrt Activation Operator.

\[out=\sqrt{x}=x^{1/2}\]

Parameters

• x (Tensor) – Input of Sqrt 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 Name.

Returns

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

(integer types are autocasted into float32).

Examples

>>> import paddle

>>> x = paddle.to_tensor([0.1, 0.2, 0.3, 0.4])
>>> out = paddle.sqrt(x)
>>> print(out)
Tensor(shape=[4], dtype=float32, place=Place(cpu), stop_gradient=True,
[0.31622776, 0.44721359, 0.54772258, 0.63245553])
