torch (version 0.8.1)

torch_combinations: Combinations

Description

Combinations

Usage

torch_combinations(self, r = 2L, with_replacement = FALSE)

Arguments

self

(Tensor) 1D vector.

r

(int, optional) number of elements to combine

with_replacement

(boolean, optional) whether to allow duplication in combination

combinations(input, r=2, with_replacement=False) -> seq

Compute combinations of length \(r\) of the given tensor. The behavior is similar to python's itertools.combinations when with_replacement is set to False, and itertools.combinations_with_replacement when with_replacement is set to TRUE.

Examples

if (torch_is_installed()) {

a = c(1, 2, 3)
tensor_a = torch_tensor(a)
torch_combinations(tensor_a)
torch_combinations(tensor_a, r=3)
torch_combinations(tensor_a, with_replacement=TRUE)
}
