Function cross_entropy_loss   
pub fn cross_entropy_loss(
    inp: &Tensor,
    target: &Tensor,
) -> Result<Tensor, Error>Expand description
The cross-entropy loss.
Arguments
- [inp]: The input tensor of dimensions 
N, CwhereNis the batch size andCthe number of categories. This is expected to raw logits. - [target]: The ground truth labels as a tensor of u32 of dimension 
N. 
The resulting tensor is a scalar containing the average value over the batch.
