What is the TensorFlow machine intelligence platform?

TensorFlow is an open source software library for numerical computation using data-flow graphs. It was originally developed by the Google Brain Team within Google's Machine Intelligence research organization for machine learning and deep neural networks research, but the system is general enough to be applicable in a wide variety of other domains as well. It reached version 1.0 in February 2017, and has continued rapid development, with 21,000 commits thus far, many from outside contributors. This article introduces TensorFlow, its open source community and ecosystem, and highlights some interesting TensorFlow open sourced models. It runs on nearly everything: GPUs and CPUs--including mobile and embedded platforms--and even tensor processing units (TPUs), which are specialized hardware to do tensor math on.
