I was able to install this fairly easily (much more so then the crap they dumped out here - https://github.com/apple/tensorflow_macos. Just take a look at the 200 github issues that were ignored for the most part...)
I also noticed that in my project I got a decent speedup immediately when executing my model, but I have not run any benchmarks.
But, where do you go to file bugs? Ask questions? etc. I am not a big Mac developer, so is there something I don't know?
