mindspore.ops.sort

mindspore.ops.sort(input_x, axis=- 1, descending=False)[source]

Sorts the elements of the input tensor along the given dimension in the specified order.

Parameters

  • input_x (Tensor) – The input tensor to sort. The shape is \((N,*)\) where \(*\) means, any number of additional dimensions.

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

  • descending (bool, optional) – Controls the sort order. If descending is True, the elements are sorted in descending order, or else sorted in ascending order. Default: False.

Warning

Currently, the data types of Float16, UInt8, Int8, Int16, Int32, Int64 are well supported. If use Float32, it may cause loss of accuracy.

Returns

  • y1, a tensor whose values are the sorted values, with the same shape and data type as input.

  • y2, a tensor that consists of 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 input_x is neither float16, float32, uint8, int8, int16, int32, int64.

  • ValueError – If axis is not in range of [-len(input_x.shape), len(input_x.shape)).

Supported Platforms:

Ascend GPU CPU

Examples

>>> x = Tensor(np.array([[8, 2, 1], [5, 9, 3], [4, 6, 7]]), mindspore.float16)
>>> output = ops.sort(x)
>>> # The output below is based on the Ascend platform.
>>> print(output)
