Intelligent Mobile Projects with TensorFlow

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.

Using fast neural-style transfer models in iOS

It turns out that we'll have no problem using the fst_frozen_quantized.pb model file, generated in step 7, in an iOS app built with the TensorFlow-experimental pod as shown in Chapter 2, Classifying Images with Transfer Learning, but the pre-trained multi-style model file from the TensorFlow Magenta project, which we'll use in a later section of this chapter, won't load with the TensorFlow pod (as of January 2018)—it'll throw the following error when trying to load the multi-style model file:

Could not create TensorFlow Graph: Invalid argument: No OpKernel was registered to support Op 'Mul' with these attrs. Registered devices: [CPU], Registered kernels:
