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.

Training layers

In earlier sections, we built the layers of a LeNet network required for inference and added inputs of image pixels and the label corresponding to each image. In this section, we are adding a few layers at the end of the network required to compute the loss function and for backpropagation. These layers are only required during training and can be discarded when using the trained network for inference.

Loss layer

As we noted in the Introduction to training section, we need a loss function at the end of the network to determine the error of the network. Caffe2 provides implementations of many common loss functions as operators in its operators' catalog.

For this example, we compute the loss value using...
