tensor.log

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

Computes the natural log of all elements of the input tensor.

$$y_i=log({x_i})$$

Args

• self(@Tensor<T>) - The input tensor.

Returns

Returns a new tensor in T with the natural log of the elements of the input tensor.

Type Constraints

Constrain input and output types to fixed point tensors.

Examples

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

use orion::operators::tensor::{TensorTrait, Tensor, FP8x23Tensor};
use orion::numbers::{FP8x23, FixedTrait};

    let tensor = TensorTrait::<FP8x23>::new(
        shape: array![2, 2].span(), 
        data: array![

    return tensor.log();
