tensor.optional

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

Constructs an optional-type value containing either an empty optional of a certain type specified by the attribute, or a non-empty value containing the input element.

Args

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

Returns

The optional output enclosing the input element.

Examples

use core::option::OptionTrait;
fn optional_example() -> Option<Tensor<T>> {
    let a = TensorTrait::<
        FP16x16
    >::new(
        shape: array![4, 2].span(),
        data: array![
           1_i8,
           2_i8,
           3_i8,
           4_i8,
