sqrt

paddle. sqrt ( x, name=None )

Warning: API “paddle.fluid.layers.layer_function_generator.sqrt” is deprecated since 2.0.0, and will be removed in future versions. Please use “paddle.sqrt” instead.

Sqrt Activation Operator.

\(out=\\sqrt{x}=x^{1/2}\)

Note:

input value must be greater than or equal to zero.

Parameters
  • x (Tensor) – Input of Sqrt operator, an N-D Tensor, with data type float32, float64 or float16.

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

Returns

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

Return type

out (Tensor)

Examples

import paddle

x = paddle.to_tensor([0.1, 0.2, 0.3, 0.4])
out = paddle.sqrt(x)
print(out)
# [0.31622777 0.4472136  0.54772256 0.63245553]
