zheng-da commented on issue #9740: add axis support and gradient for L2norm
URL: https://github.com/apache/incubator-mxnet/pull/9740#issuecomment-364617485
   @piiswrong how many ord should we support?
   We can support ord=1, inf and None.
   I guess ord=0 isn't differentiable.
   What is the definition of ord=2 for an NDArray? When the array is a vector, 
it's easy. When the array is a matrix, it's the largest singular value. What is 
the gradient? What is the definition of L2 for an array with more than 2
