This operator is too complex to be implemented into Gorgonnx as it is more than a composition of other existing functions.
I think that there is a need for a new Op in gorgonia.

The implementation has started in Gorgonia see this branch

What's the difference between Gorgonnx and Gorgonia?

[owulveryck]

Hi,

Gorgonia is a library used for computation and automatic differentiation (like tensorflow).
It’s not compatible with the interfaces of onnx-go (yet), but very close.
Gorgonnx is a transitional package made to fill the gap. It acts a a transpiler from onnx-go to Gorgonia.

Hope this helps
