HF pipeline to run Ultravox independent of Ultravox repo

[farzadab]

Right now you can load the model without having access to the repo using:

# pip install transformers peft

import transformers
import numpy as np

pipe = transformers.pipeline(model='fixie-ai/ultravox-v0_2', trust_remote_code=True)

pipe({'audio': np.random.randn(16000), 'sampling_rate': 16000}, max_new_tokens=30)

The result is gonna be:

"assistant\n\nI'm here to help! What's on your mind?"

I ran into multiple issues with HF Hub to get this working. As a result I had to make two sacrifices:

1. change HF Hub repo name so it doesn't contain any dots (.): fixie-ai/ultravox-v0.2 -> fixie-ai/ultravox-v0_2
   • The original name should still work as it redirects to the new address
2. imports in ultravox/model directory had to break the style guide, e.g. from .ultravox_config import UltravoxConfig
