As of TensorFlow 1.9, Python wheels for TensorFlow are being officially supported. As such, this repository is no longer recommended for your TensorFlow on RPi needs; use the official sources!
You can install the official wheel with the following commands, assuming you are using Raspbian 9:
sudo apt install libatlas-base-dev pip3 install tensorflow
It was a fun ride! With Raspberry Pi support now official, I will no longer be looking to update this repository. I'm sorry that I wasn't able to continue maintaining the repo as much as I wanted, but it was amazing watching the community continue to thrive.
