https://huggingface.co/colbert-ir/colbertv2.0 with ONNX weights to be compatible with Transformers.js.
Usage (Transformers.js)
If you haven't already, you can install the Transformers.js JavaScript library from NPM using:
npm i @xenova/transformers
You can then use the model to compute embeddings like this:
import { pipeline } from '@xenova/transformers';
// Create a feature-extraction pipeline
const extractor = await pipeline('feature-extraction', 'Xenova/colbertv2.0');
// Compute sentence embeddings
const sentences = ['Hello world', 'This is a sentence'];
const output = await extractor(sentences, { pooling: 'mean', normalize: true });
console.log(output);
// Tensor {
// dims: [ 2, 768 ],
// type: 'float32',
// data: Float32Array(768) [ -0.008133978582918644, 0.00663341861218214, ... ],
// size: 768
// }
You can convert this Tensor to a nested JavaScript array using .tolist():
console.log(output.tolist());
// [
// [ -0.008133978582918644, 0.00663341861218214, 0.06555338203907013, ... ],
// [ -0.02630571834743023, 0.011146597564220428, 0.008737687021493912, ... ]
// ]
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 and structuring your repo like this one (with ONNX weights located in a subfolder named onnx).
