Support onnx conversion for wav2vec2-bert

[fawazahmed0]

System Info

transformers.js@main

Who can help?

@xenova

It is mentioned in that wav2vec2-bert is supported in transformers.js.
I tried converting wav2vec2-bert to onnx by following this doc.

Information

• The official example scripts
• My own modified scripts

Tasks

• An officially supported task in the examples folder (such as GLUE/SQuAD, ...)
• My own task or dataset (give details below)

Reproduction (minimal, reproducible, runnable)

python -m scripts.convert --quantize --model_id Yehor/w2v-bert-uk-v2.1

(mypy) C:\Users\Nawaz-Server\Documents\ml\transformers.js>python -m scripts.convert --quantize --model_id Yehor/w2v-bert-uk-v2.1

Caching files will still work but in a degraded version that might require more space on your disk. This warning can be disabled by setting the `HF_HUB_DISABLE_SYMLINKS_WARNING` environment variable.

To support symlinks on Windows, you either need to activate Developer Mode or to run Python as an administrator. In order to activate developer mode, see this article: https://docs.microsoft.com/en-us/windows/apps/get-started/enable-your-device-for-development

Expected behavior

Onnx Conversion should work

Hi there 👋 I exported it using this draft branch: #1670

Once I have a bit of bandwidth, I can return to the PR, just to add the final unit tests and merge.

Let me know if that works for you. 👍

Thanks, I merged your PR and did pip install optimum[onnxruntime]@git+https://github.com/fawazahmed0/optimum.git and the conversion was successful 👍
