tensor.sign

   fn sign(self: @Tensor<T>) -> Tensor<T>;

Calculates the sign of the given input tensor element-wise. If input > 0, output 1. if input < 0, output -1. if input == 0, output 0.

Args

• self(@Tensor<T>) - Tensor of data to calculates the sign of the given input tensor element-wise.

Returns

A new Tensor<T> of the same shape as the input tensor with The sign of the input tensor computed element-wise.

Example

use core::array::{ArrayTrait, SpanTrait};

use orion::operators::tensor::{TensorTrait, Tensor, I32Tensor};

fn sign_example() -> Tensor<i32> {
    let tensor = TensorTrait::<i32>::new(
        shape: array![11].span(), 
        data: array![-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5].span(), 
    );

    return tensor.sign();
