Install

Create a new conda environment and install the required packages:

conda create -n omni python=3.10
conda activate omni

git clone https://github.com/gpt-omni/mini-omni.git
cd mini-omni
pip install -r requirements.txt

Quick start

Interactive demo

start server

conda activate omni
cd mini-omni
python3 server.py --ip '0.0.0.0' --port 60808

run streamlit demo

NOTE: you need to run streamlit locally with PyAudio installed.

pip install PyAudio==0.2.14
API_URL=http://0.0.0.0:60808/chat streamlit run webui/omni_streamlit.py

run gradio demo

API_URL=http://0.0.0.0:60808/chat python3 webui/omni_gradio.py

example:

NOTE: need to unmute first. Gradio seems can not play audio stream instantly, so the latency feels a bit longer.

Local test

conda activate omni
cd mini-omni
# test run the preset audio samples and questions
