Caffe2 Quick Start Guide

By: Ashwin Nanjappa

Overview of this book

Caffe2 is a popular deep learning library used for fast and scalable training, and inference of deep learning models on different platforms. This book introduces you to the Caffe2 framework and demonstrates how you can leverage its power to build, train, and deploy efficient neural network models at scale. The Caffe 2 Quick Start Guide will help you in installing Caffe2, composing networks using its operators, training models, and deploying models to different architectures. The book will also guide you on how to import models from Caffe and other frameworks using the ONNX interchange format. You will then cover deep learning accelerators such as CPU and GPU and learn how to deploy Caffe2 models for inference on accelerators using inference engines. Finally, you'll understand how to deploy Caffe2 to a diverse set of hardware, using containers on the cloud and resource-constrained hardware such as Raspberry Pi. By the end of this book, you will not only be able to compose and train popular neural network models with Caffe2, but also deploy them on accelerators, to the cloud and on resource-constrained platforms such as mobile and embedded hardware.

Caffe2 at the Edge and in the cloud

In chapters 1-6 of this book, we have learned how to install and use Caffe2 to train DL neural networks and how to work with other popular DL frameworks. We have also learnt how to deploy our trained Caffe2 models on popular inference engines. In this last chapter, we will look at applications of Caffe2 that exploit its ability to scale from tiny edge devices such as the Raspberry Pi to running on containers in the cloud. We will also look at visualizing Caffe2 models.

The topics that will be covered in this chapter are as follows:

  • Caffe2 at the edge on Raspberry Pi
  • Caffe2 in the cloud using containers
  • Caffe2 model visualization
