> A 2D softmax layer would accept a tensor of shape {{(N,C,H,W)}}, where the {{C}} axis
contains scores for {{D}} classes, and output a tensor of the same shape, with the scores
transformed to normalized probabilities.  The typical use case would be a segmentation problem,
in which every pixel has a multiclass prediction.
