mindspore.ops.repeat_elements

mindspore.ops.repeat_elements(x, rep, axis=0)[source]

Repeat elements of a tensor along an axis, like mindspore.numpy.repeat() .

Note

It is recommended to use :func:'mindspore.mint.repeat_interleave', the dimension of input 'x' can support a maximum of 8, and get better performance.

Parameters

x (Tensor) – The input tensor.
rep (int) – The number of times to repeat, must be positive.
axis (int) – The axis along which to repeat. Default 0.

Returns

Tensor

Supported Platforms:: Ascend GPU CPU

Examples

>>> import mindspore
>>> # case 1 : repeat on axis 0
>>> x = mindspore.tensor([[0, 1, 2], [3, 4, 5]], mindspore.int32)
>>> output = mindspore.ops.repeat_elements(x, rep = 2, axis = 0)
>>> print(output)
[[0 1 2]
 [0 1 2]
 [3 4 5]
 [3 4 5]]
>>> # case 2 : repeat on axis 1
>>> x = mindspore.tensor([[0, 1, 2], [3, 4, 5]], mindspore.int32)
>>> output = mindspore.ops.repeat_elements(x, rep = 2, axis = 1)
>>> print(output)
[[0 0 1 1 2 2]
 [3 3 4 4 5 5]]
