mindspore.ops.unique

mindspore.ops.unique(input)[source]

Remove duplicate elements from the input tensor.

Warning

Non-backward-compatible change after version 2.9.0: the current default return (output, indices) will be changed so that only output is returned by default.

Parameters

input (Tensor) – The input tensor.

Returns

Tuple(output, indices) of 2 tensors.

output (Tensor) - The deduplicated output tensor.
indices (Tensor) - The indices of the elements of the input tensor in the output .

Supported Platforms:: Ascend GPU CPU

Examples

>>> import mindspore
>>> x = mindspore.tensor([1, 2, 5, 2], mindspore.int32)
>>> output, indices = mindspore.ops.unique(x)
>>> print(output)
[1 2 5]
>>> print(indices)
[0 1 2 1]
