I'm sorry but I think you don't know what you're looking at - of the NN things in the top 50 there I see 4 such wrappers. The remainder are the NN frameworks and various perf motivated implementations.

Also I don't know how this list is built but it seems to be literally measuring current popular things - so by definition no matter when i visit this list whatever is it at the top will probably wane in population shortly after I've visited.
