// Note [Empty versus 0-dim tensors]
// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
// Unlike Torch, ATen treats zero-dimension tensors as having ONE
// element (that is to say, a zero-dimensional tensor is a scalar!)
// This is in contrast to Torch, where a zero-dimension tensor has
// zero elements.
//
// Because we are backed by Torch tensors, we need to be able to
// represent this state (of numel==0).  These tensors are represented
// by one-dimensional tensors with size[0] == 0 and stride[0] == 1
// (the stride is arbitrary but matches the NumPy equivalent).
