I read about Edge recently.

It allows NodeJS programs to interop with .NET - including IronPython - which can be used to execute python scripts.

Perhaps there are other ways for NodeJS to interop with python without involving .NET? I did see a few but they looked like they spawned child processes which looked.. nasty.

I have absolutely no idea whether this would be a valid approach for your port but I immediatley thought perhaps creating some sort of interop with the python parts of tensorflow rather than a full translation of python into c++ might be a viable?

I have no real expertise in this area, just raising so someone with some expertise can either look into further or immediately shoot this idea down! :)
