Deeplearn-Caffe

Run pretrained Caffe models in the browser with GPU support via the wonderful deeplearn.js library. This package provides utility tools and a model loader for Caffe models to support the following tasks:

• Loading and parsing *.caffemodel files into deeplearn.js weights
• Loading and parsing *.binaryproto files into deeplearn.js blobs
• Loading and parsing *.prototxt files into deeplearn.js models

Usage

Installation

You can use this as standalone es5 bundle like this:

<script src="https://unpkg.com/deeplearn-caffe"></script>

Then loading model is a simple as referencing the path to the caffemodel and prototxt files.

Here is an example of loading GoogLeNet:

var GITHUB_CDN = 'https://rawgit.com/';
var MODEL_DIR = 'models/';
 
// Caffemodel needs to be downloaded from here
var modelUrl = 'http://dl.caffe.berkeleyvision.org';
 
var prototxtUrl = GITHUB_CDN + 'BVLC/caffe/master/models/bvlc_googlenet/deploy.prototxt';
var caffemodelUrl = MODEL_DIR + 'bvlc_googlenet.caffemodel';
 
// Initialize the CaffeModel
var model = new deeplearnCaffe.CaffeModel(caffemodelUrl, prototxtUrl);

This is how you load Squeezenet directly from Github:

// The model is served entirely from Github
var GITHUB_CDN = 'https://rawgit.com/';
 
var prototxtUrl = GITHUB_CDN + 'DeepScale/SqueezeNet/master/SqueezeNet_v1.1/deploy.prototxt';
var caffemodelUrl = GITHUB_CDN + 'DeepScale/SqueezeNet/master/SqueezeNet_v1.1/squeezenet_v1.1.caffemodel';
 
// Initialize the CaffeModel
var model = new deeplearnCaffe.CaffeModel(caffemodelUrl, prototxtUrl);

Run Demos

To run the demo, use the following:

npm run build
 
# Start a webserver 
npm run start

Now navigate to http://localhost:8080/demos.

Hint: some of the models are quite big (>30MB). You have to download the caffemodel files and place them into the demos/models directory to save bandwith.

Development

npm install

To build a standalone bundle run

npm run build
