# MobileNet tfjs-backend-nodegl Demo

*This is a very early demo to show how tfjs-backend-nodegl can be used for headless WebGL acceleration.*

To run this demo, perform the following:

1. Move into `tfjs-backend-nodegl` (parent directory of this demo folder):
```sh
$ cd tfjs-backend-nodegl
```

2. Build package and compile TypeScript:
```sh
$ yarn && yarn tsc
```

3. Move into the demo directory:
```sh
$ cd demo
```

4. Prep and build demo:
```sh
$ yarn
```

5. Run demo:
```sh
$ node run_mobilenet_inference.js dog.jpg
```

Expected output:
```sh
$ node run_mobilenet_inference.js dog.jpg
