TensorFlow on Raspberry Pi: Just in Time for Pi Day!

This work was truly a team effort, so please check out the credits of the repo and give everyone there a warm e-hug. Earlier today, I released instructions for compiling TensorFlow on the Raspberry Pi 3, as well as a pre-built Python wheel that can be used to install it directly. I'm hoping that this will enable some really cool projects involving both portable GPIO device-based learning and experimentation with TensorFlow's distributed runtime. This has been an effort that has gone on since TensorFlow was open-sourced, and I'm really happy to be part of the group of people that made it happen. There are two main attractions to the repository: a pre-built Python wheel that can be used to easily install TensorFlow on a Raspberry Pi 3, and a step-by-step guide to building TensorFlow yourself.
