Welcome to the age of voice-responsive technology! In this article, we’re diving into how to set up and utilize the LLaMA-Omni model, a cutting-edge speech-language model built on the Llama-3.1-8B-Instruct architecture. This innovative platform enables low-latency, high-quality speech interactions, capable of generating both text and audio responses based on your spoken instructions.

Getting Started with LLaMA-Omni

Let’s break down the process into manageable steps for easy installation and usage. Think of this as hosting a vast dinner party (your speech model) where you need to gather ingredients (code and configurations) before serving the guests (users).

Step-by-Step Installation

• Clone the Repository:

  To begin, you’ll need to clone the LLaMA-Omni repository:

  git clone https://github.com/ictnlp/LLaMA-Omni
  cd LLaMA-Omni

• Install Dependencies:

  Create a new conda environment and install necessary packages:

  conda create -n llama-omni python=3.10
  conda activate llama-omni
  pip install pip==24.0
  pip install -e .

• Install Additional Libraries:

  Next, install fairseq and flash-attention:

  git clone https://github.com/pytorch/fairseq
  cd fairseq
  pip install -e . --no-build-isolation
  pip install flash-attn --no-build-isolation

Quick Start Guide

Now that you have the base model installed, it’s time to get LLaMA-Omni up and running. Think of it as prepping the dining table before your guests arrive.

1. Download the Model:

   First, download the Llama-3.1-8B-Omni model:

   Huggingface Model

2. Set up the Whisper Model:

   Next, download the Whisper-large-v3 model:

   import whisper
   model = whisper.load_model("large-v3", download_root="models/speech_encoder")

3. Download the Vocoder:

   You will also need to download the HiFi-GAN vocoder:

   wget https://dl.fbaipublicfiles.com/fairseq/speech_to_speech/vocoder/code_hifigan_mhubert_vp_en_es_fr_it3_400k_layer11_km1000_lj/0_0500000 -P vocoder
   wget https://dl.fbaipublicfiles.com/fairseq/speech_to_speech/vocoder/code_hifigan_mhubert_vp_en_es_fr_it3_400k_layer11_km1000_lj/config.json -P vocoder

Interacting with LLaMA-Omni

After the setup, you can now serve and interact with your LLaMA-Omni model:

1. Launch the Controller:

   python -m omni_speech.serve.controller --host 0.0.0.0 --port 10000

2. Start the Gradio Web Server:

   python -m omni_speech.serve.gradio_web_server --controller http://localhost:10000 --port 8000 --model-list-mode reload --vocoder vocoder_g_00500000 --vocoder-cfg vocoder/config.json

3. Run the Model Worker:

   python -m omni_speech.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-path Llama-3.1-8B-Omni --model-name Llama-3.1-8B-Omni --s2s

4. Visit Your Local Instance:

   Finally, navigate to http://localhost:8000 to start interacting!

Troubleshooting Tips

If you encounter issues during the setup or usage, here are a few troubleshooting ideas:

• Ensure that all paths in your scripts are correct; it’s easy to misplace a file.
• Check internet connectivity when downloading models to avoid errors.
• If you face issues with Gradio’s audio playback, consider disabling autoplay or researching other streaming methods.
