[TensorFlow](https://www.tensorflow.org/) is open-source machine learning software used to train neural networks, expressed in the form of [stateful dataflow graphs](https://www.tensorflow.org/programmers_guide/graphs). In this tutorial, we’ll install TensorFlow’s “CPU support only” version, ideal for those without an Nvidia graphics card or the need to run performance-critical applications.
