Hertz-dev is an open-source, first-of-its-kind base model for full-duplex conversational audio.
See our blog post for more details: https://si.inc/hertz-dev/
Inference is known to work on Python 3.10 and CUDA 12.1. Other versions have not been tested as thoroughly. If you want to use CUDA 12.1, you'll need to install torch with pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121 before running pip install -r requirements.txt.
On Ubuntu you may need to install libportaudio: sudo apt-get install libportaudio2
All three scripts will automatically download the models to the ./ckpt directory, and checkpoints are also accessible at https://ckpt.si.inc/hertz-dev/index.txt
We recommend starting by using inference.ipynb to generate one- or two-channel completions from a prompt.
Then, you can use inference_client.py and inference_server.py to talk to the model live through your microphone.
These are currently experimental, and have primarily been tested with Ubuntu on the server and MacOS on the client.
