One of the benefits of using a good deep learning framework, such as TensorFlow, is its seamless support for using a Graphical Processing Unit (GPU) in model training. It'd be a lot faster training a non-trivial TensorFlow-based model on a GPU than on a CPU, and currently NVIDIA offers the best and most cost-effective GPUs supported by TensorFlow. And Ubuntu is the best OS for running NVIDIA GPUs with TensorFlow. You can easily buy one GPU for a few hundred bucks and install it on an inexpensive desktop with an Ubuntu system. You can also install NVIDIA GPU on Windows but TensorFlow's support for Windows is not as good as that for Ubuntu.
To train the models deployed in the apps in this book, we ...
