torch (version 0.8.1)

torch_narrow: Narrow

Description

Narrow

Usage

torch_narrow(self, dim, start, length)

Arguments

self

(Tensor) the tensor to narrow

dim

(int) the dimension along which to narrow

start

(int) the starting dimension

length

(int) the distance to the ending dimension

narrow(input, dim, start, length) -> Tensor

Returns a new tensor that is a narrowed version of input tensor. The dimension dim is input from start to start + length. The returned tensor and input tensor share the same underlying storage.

Examples

if (torch_is_installed()) {

x = torch_tensor(matrix(c(1:9), ncol = 3, byrow= TRUE))
torch_narrow(x, 1, 1, 2)
torch_narrow(x, 2, 2, 2)
}
