A photo gallery with a facial recognition API called face-api.js

face-api.js Testing Project

This is a testing project for facial recognition using face-api.js. This is my first project using nodejs and electron as I am not too familiar with JS or HTML, so excuse the bad code.

I had troubles initially getting everything to run properly because canvas was not cooperating with electron on my end. I will include a list of problems that arose for me and the solutions I took. First, please follow the installation instructions for node-canvas.

Instructions

npm i
npm start

A folder dialog will appear prompting you to select the folder which you want to view the contents of as well as run the facial recognition against.

In order to change the database of the facial recognition, or training data if you will, you have to manually change that yourself over at assets/test-data-set.

Troubleshooting

With the addition of the "postinstall" script within package.json this should resolve the error with Canvas. Additionally, as a result, the tfjs error did not occur for me either, either because of this change or the updated dependencies.

Canvas, canvas.node was compiled against a different Node.js version

Uncaught Error: The module '\Face-API\node_modules\canvas\build\Release\canvas.node' was compiled against a different Node.js version using NODE_MODULE_VERSION 72. This version of Node.js requires NODE_MODULE_VERSION 70. Please try re-compiling or re-installing the module (for instance, using npm rebuild or npm install).

canvas.node Solution

Follow instructions for electron-rebuild. For me, since I am on windows, I ran the following ./node_modules/.bin/electron-rebuild. With the addition of the "postinstall" script, this should no longer happen. However, should the case still arise, the instructions above still works.

You could also try running npm rebuild canvas --update-binary alone.

TFJS Errors, specified module could not be found... tfjs_binding.node

After I solved that issue I came across another issue regarding tfjs.

Initialization of backend tensorflow failed

Error: The specified module could not be found. \node_modules@tensorflow\tfjs-node\build\Release\tfjs_binding.node

TFJS Solution

All I did was rebuild the project with npm rebuild which resolved this error for me.

Cannot find module... napi-v{version}/tfjs_binding.node

napi-v{version}/tfjs_binding.node Solution

Make sure that your node.js version corresponds with the node.js version respective to electron. For example, as of Janurary 4th, 2020, the latest Electron version is 7.1.7 and it was compiled with node.js v12.8.1, so you would want to make sure your machine is also running node.js v12.8.1. This is how I resolved this error.

See tensorflow/tfjs#2640 for more details.
