mindspore.ops.Sort

class mindspore.ops.Sort(axis=-1, descending=False)[source]

Sorts the elements of the input tensor along a given dimension in ascending order by value.

Parameters

  • axis (int) – The dimension to sort along. Default: -1.

  • descending (bool) – Controls the sorting order. If descending is True then the elements are sorted in descending order by value. Default: False.

Inputs:

  • x (Tensor) - The input to sort, with float16 or float32 data type. The shape is \((N,*)\) where \(*\) means,any number of additional dimensions.

Outputs:

  • y1 (Tensor) - A tensor whose values are the sorted values, with the same shape and data type as input.

  • y2 (Tensor) - The indices of the elements in the original input tensor. Data type is int32.

Raises

  • TypeError – If axis is not an int.

  • TypeError – If descending is not a bool.

  • TypeError – If dtype of x is neither float16 nor float32.

Supported Platforms:

Ascend GPU CPU

Examples

>>> x = Tensor(np.array([[8, 2, 1], [5, 9, 3], [4, 6, 7]]), mindspore.float16)
>>> sort = ops.Sort()
>>> output = sort(x)
>>> print(output)
