https://huggingface.co/google/owlv2-base-patch16-finetuned with ONNX weights to be compatible with Transformers.js.


## Usage (Transformers.js)

If you haven't already, you can install the [Transformers.js](https://huggingface.co/docs/transformers.js) JavaScript library from [NPM](https://www.npmjs.com/package/@xenova/transformers) using:
```bash
npm i @xenova/transformers
```

**Example:** Zero-shot object detection w/ `Xenova/owlv2-base-patch16-finetuned`.
```js
import { pipeline } from '@xenova/transformers';

const detector = await pipeline('zero-shot-object-detection', 'Xenova/owlv2-base-patch16-finetuned');

const url = 'http://images.cocodataset.org/val2017/000000039769.jpg';
const candidate_labels = ['a photo of a cat', 'a photo of a dog'];
const output = await detector(url, candidate_labels);
console.log(output);
// [
//   { score: 0.6951543688774109, label: 'a photo of a cat', box: { xmin: 326, ymin: 23, xmax: 650, ymax: 376 } },
//   { score: 0.5766839385032654, label: 'a photo of a cat', box: { xmin: 6, ymin: 63, xmax: 315, ymax: 487 } }
// ]
```

Note: Having a separate repo for ONNX weights is intended to be a temporary solution until WebML gains more traction. If you would like to make your models web-ready, we recommend converting to ONNX using [🤗 Optimum](https://huggingface.co/docs/optimum/index) and structuring your repo like this one (with ONNX weights located in a subfolder named `onnx`).
