mindspore.ops.Rsqrt

class mindspore.ops.Rsqrt[source]

Computes reciprocal of square root of input tensor element-wise.

Refer to mindspore.ops.rsqrt() for more details.

Inputs:

x (Tensor) - The input Tensor, each element must be a non-negative, if an element is negative, the calculation result is nan.

Outputs:

Tensor, has the same type and shape as x.

Supported Platforms:

Ascend GPU CPU

Examples

>>> import mindspore
>>> from mindspore import Tensor, ops
>>> input_tensor = Tensor([[4, 4], [9, 9]], mindspore.float32)
>>> rsqrt = ops.Rsqrt()
>>> output = rsqrt(input_tensor)
>>> print(output)
[[0.5        0.5       ]
 [0.33333334 0.33333334]]
