mindspore.ops.repeat_elements

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

Repeat elements of a tensor along an axis, like np.repeat .

Parameters

x (Tensor) – The tensor to repeat values for. Must be of type: float16, float32, int8, uint8, int16, int32, or int64.
rep (int) – The number of times to repeat, must be positive.
axis (int) – The axis along which to repeat. Default: 0.

Returns

One tensor with values repeated along the specified axis. If x has shape \((s1, s2, ..., sn)\) and axis is i, the output will have shape \((s1, s2, ..., si * rep, ..., sn)\). The output type will be the same as the type of x.

Supported Platforms:: Ascend GPU CPU

Examples

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