Howto include permutohedral op in MXNet?

[MarvinTeichmann]

Hi Eric,

thanks for sharing you permutohedral lattice implementation. It looks like amazing work. I am trying to implement CRFasRNN into MxNet and would like to use your permutohedral cuda implementation.

I have tried cloning this repository to $MXNET/plugin/permutohedral, building mxnet from source and run test.py. However I am getting the error:

Traceback (most recent call last):
  File "test.py", line 178, in <module>
    sym = mx.sym.Permutohedral(data=mx.sym.Variable('val'), pos=mx.sym.Variable('pos'), normalize=norm)
AttributeError: 'module' object has no attribute 'Permutohedral'

I am using mxnet Version 0.9.5 under Linux. Is you implementation compatible with the 0.9 way of defining ops? What steps should I do to make test.py work?
