Function l1_norm 

pub fn l1_norm<const D: usize, K>(
    x: Tensor<D, K>,
    dim: impl AsIndex,
) -> Tensor<D, K>
where
    K: Numeric,

Computes the L1 norm of a tensor along a specified dimension.

This is a convenience function that wraps vector_norm with p = 1.0.

Arguments

• x - The input tensor.
• dim - The dimension to compute the norm over. Negative dimensions are supported and count from the end.

Returns

The L1 norm of the input tensor.
