Take

Take

torch_take(self, index)

Arguments

self	(Tensor) the input tensor.
index	(LongTensor) the indices into tensor

take(input, index) -> Tensor

Returns a new tensor with the elements of input at the given indices. The input tensor is treated as if it were viewed as a 1-D tensor. The result takes the same shape as the indices.

Examples

if (torch_is_installed()) {

src = torch_tensor(matrix(c(4,3,5,6,7,8), ncol = 3, byrow = TRUE))
torch_take(src, torch_tensor(c(1, 2, 5), dtype = torch_int64()))
}
