Description

This is a repost of https://github.com/xenova/transformers.js/issues/764

Using the repository from : https://github.com/xenova/transformers.js/tree/v3/examples/webgpu-chat and "@xenova/transformers": "github:xenova/transformers.js#v3", it gets stuck on loading model with error in chrome console:

@xenova_transformers.js?v=ef40148f:1386 Uncaught (in promise) Error: no available backend found. ERR: [webgpu] TypeError: Failed to fetch dynamically

@xenova, I've verified that the branch I checked out last night has the two commits you mention here. Thanks for your continued support of this project!!

Reproduction

1. Clone repo from https://github.com/xenova/transformers.js/tree/v3/examples/webgpu-chat
2. npm i and do npm run dev;
3. Go to url
4. Load Model
5. Model gets stuck on ...loading...
