Ptn Cross Entropy Loss

A class to compute the cross entropy loss.

Unlike Ptn NLL Loss node which takes log probabilities for input, input to this node needs to be logits. You can consider this node as a combination of log softmax and NLL.

Args:  
    reduction: (str): Reduction method.  
                      `none`: no reduction will be applied done.   
                      `mean`: computes the mean.  
                      `sum`: computes the sum.
