As for TensorFlow, it's a Python-friendly open source library invented by the Google Brain team for high-performance numerical computation. It makes machine learning faster and deep learning easier with the Python-based convenient frontend API and high-performance C++ based backend execution. Plus, it allows easy deployment of computation across CPUs and GPUs, which empowers expensive and large-scale machine learning. In this book, we focus on CPU as our computation platform. Hence, according to https://www.tensorflow.org/install/, installing TensorFlow is done via the following command line:

pip install tensorflow

There are many other packages we'll be using intensively, for example, Matplotlib for plotting and visualization, ...
