tensor.gather
fn gather(self: @Tensor<T>, indices: Tensor<T>, axis: Option<usize>) -> Tensor<T>;
Gather entries of the axis dimension of data.
self(@Tensor<T>) - The input tensor.indices(Tensor<T>) - Tensor of indices.axis(Option<usize>) - Axis to gather on. Default: axis=0.
- Panics if index values are not within bounds [-s, s-1] along axis of size s.
A new
Tensor<T> .use array::{ArrayTrait, SpanTrait};
use orion::operators::tensor::{TensorTrait, Tensor, U32Tensor};
fn gather_example() -> Tensor<u32> {
let tensor = TensorTrait::<u32>::new(
shape: array![2, 3].span(),
data: array![[ 1, 2, 3],[4, 5, 6]].span(),
);
let indices = TensorTrait::<u32>::new(
shape: array![1, 1].span(),
data: array![1, 0].span(),
);
return tensor.gather(
indices: indices,
axis: Option::None(()),
);
}
