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 the drawing classification model in iOS

To fix the previous RefSwitch error, which will occur no matter whether you use the TensorFlow Pod as we did in Chapter 2, Classifying Images with Transfer Learning, and Chapter 6, Describing Images in Natural Language, or the manually built TensorFlow library, as in the other chapters, we have to use some new trick. The error occurs because the INT64 data type is required for a RefSwitch operation, but it's not one of the registered data types built into the TensorFlow library because, by default, to make the library as small as possible, only common data types for each operation are included. We may fix this from the model building end in Python, but here we'll just show you how to fix this from the iOS end, which can be useful when you don't have access to the source code to build a model.
