Overview of this book

As a developer, you always need to keep an eye out and be ready for what will be trending soon, while also focusing on what's trending currently. So, what's better than learning about the integration of the best of both worlds, the present and the future? Artificial Intelligence (AI) is widely regarded as the next big thing after mobile, and Google's TensorFlow is the leading open source machine learning framework, the hottest branch of AI. This book covers more than 10 complete iOS, Android, and Raspberry Pi apps powered by TensorFlow and built from scratch, running all kinds of cool TensorFlow models offline on-device: from computer vision, speech and language processing to generative adversarial networks and AlphaZero-like deep reinforcement learning. You’ll learn how to use or retrain existing TensorFlow models, build your own models, and develop intelligent mobile apps running those TensorFlow models. You'll learn how to quickly build such apps with step-by-step tutorials and how to avoid many pitfalls in the process with lots of hard-earned troubleshooting tips.

Training fast neural-style transfer models

In this section, we'll show you how to train models using the fast neural-style transfer algorithm with TensorFlow. Perform the following steps to train such a model:

  1. On a Terminal of your Mac or preferably GPU-powered Ubuntu, run git clone https://github.com/jeffxtang/fast-style-transfer, which is a fork of a nice TensorFlow implementation of Johnson's fast-style transfer, modified to allow the trained model to be used in iOS or Android apps.
  2. cd to the fast-style-transfer directory, then run the setup.sh script to download the pre-trained VGG-19 model file as well as the MS COCO training dataset, which we mentioned in the previous chapter – note that it can take several hours to download the large files.
  3. Run the following commands to create checkpoint files with training using a style image named starry_night.jpg and...
