torch_repeat_interleave: Repeat_interleave

Description

Repeat_interleave

Usage

torch_repeat_interleave(self, repeats, dim = NULL)

Arguments

self

(Tensor) the input tensor.

repeats

(Tensor or int) The number of repetitions for each element. repeats is broadcasted to fit the shape of the given axis.

dim

(int, optional) The dimension along which to repeat values. By default, use the flattened input array, and return a flat output array.

repeat_interleave(input, repeats, dim=NULL) -> Tensor

Repeat elements of a tensor.

Warning

This is different from `torch_Tensor.repeat` but similar to `numpy.repeat`.

repeat_interleave(repeats) -> Tensor

If the repeats is tensor([n1, n2, n3, ...]), then the output will be tensor([0, 0, ..., 1, 1, ..., 2, 2, ..., ...]) where 0 appears n1 times, 1 appears n2 times, 2 appears n3 times, etc.

Examples

# NOT RUN {
if (torch_is_installed()) {
# }
# NOT RUN {
x = torch_tensor(c(1, 2, 3))
x$repeat_interleave(2)
y = torch_tensor(matrix(c(1, 2, 3, 4), ncol = 2, byrow=TRUE))
torch_repeat_interleave(y, 2)
torch_repeat_interleave(y, 3, dim=1)
torch_repeat_interleave(y, torch_tensor(c(1, 2)), dim=1)
# }
# NOT RUN {
}
