https://huggingface.co/AmelieSchreiber/esm2_t6_8M_UR50D_sequence_classifier_v1 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:** Protein sequence classification w/ `Xenova/esm2_t6_8M_UR50D_sequence_classifier_v1`.
```js
import { pipeline } from '@xenova/transformers';

// Create text classification pipeline
const classifier = await pipeline('text-classification', 'Xenova/esm2_t6_8M_UR50D_sequence_classifier_v1');

// Suppose these are your new sequences that you want to classify
// Additional Family 0: Enzymes
const new_sequences_0 = [
    'ACGYLKTPKLADPPVLRGDSSVTKAICKPDPVLEK',
    'GVALDECKALDYLPGKPLPMDGKVCQCGSKTPLRP',

]

// Merge all sequences
const new_sequences = [...new_sequences_0, ...new_sequences_1, ...new_sequences_2];

// Get the predicted class for each sequence
const predictions = await classifier(new_sequences);

// Output the predicted class for each sequence
for (let i = 0; i < predictions.length; ++i) {
    console.log(`Sequence: ${new_sequences[i]}, Predicted class: '${predictions[i].label}'`)

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`).
