Does mxnet NDArray have autodiff ?

Hi!

  [I'm referring to the Scala API]

  1. mxnet symbol has auto diff:
https://mxnet.incubator.apache.org/tutorials/r/symbol.html

  2. from Googling around, I can't find NDArray auto diff anywhere

  3. however, NDArray tracks dependencies -- which, in theory, should
be enough for doing autodiff

  Does NDArray have autodiff somewhere?

Thanks,
