CaffeJS - Development Guide

Getting Started

Checkout the project and run npm install in the root directory to get started. Now you can start diving into the code.

You can build your code running gulp or using the file watcher gulp watch.

Organization of the code

This library uses Typescript to modularize JavaScript code and use some of the cool Typescript features on top, such as classes, inheritance, fat arrow functions, etc.

You can find the source code in the src/ directory organized in 5 modules:

• Net - A fork of ConvNetJS with Caffe compatibility (considering model weights, output parameters, etc.); contains the ConvNetJS model Net.Net, the CaffeJS model Net.CaffeModel, the the Volume implementation Net.Vol and the layers Net.Layers
• ImgJS - An image abstraction for JavaScript to avoid dealing with canvas elements and facilitate conversion to Volumes
• NumJS - An abstraction for operations on Arrays and Volumes
• Parser - A parser for converting Prototxt and Protobuf binaries into JavaScript objects
• Utils - An abstractions for utilities and visualizations, such as the GraphDrawer and ActivationDrawer

Converting *.caffemodel files

You can use the script scripts/convert_caffemodel.py to convert *.caffemodel files to binary blobs which CaffeJS can load via http and parse. Unfortunately, you need to have Caffe and pycaffe installed to generate those files. You can as well download the prepared weights via running sh fetch_weights.sh in the model directories.

Deploy the docs

Run gulp deploy to build the docs-pages folder and deploy it to Github.
