Overview

This project is a real-time live streaming digital human powered by few-shot learning. It is designed to run smoothly on all 30 and 40 series graphics cards, ensuring a seamless and interactive live streaming experience.

Key Features

• Real-time Performance: The digital human can interact in real-time with 25+ fps for common NVIDIA 30 and 40 series GPUs
• Few-shot Learning: The system is capable of learning from a few examples to generate realistic responses.

Usage

Create Environment and Unzip the Model File

First, navigate to the checkpoint directory and unzip the model file:

conda create -n dh_live python=3.12
conda activate dh_live
pip install torch --index-url https://download.pytorch.org/whl/cu124
pip install -r requirements.txt
cd checkpoint

on Linux

cat render.pth.gz.001 render.pth.gz.002 > render.pth.gz
gzip -d -c render.pth.gz > render.pth

on Windows, use zip software such as 7zip/WinRAR to unzip checkpoint file.

Prepare Your Video

Next, prepare your video using the data_preparation script. Replace YOUR_VIDEO_PATH with the path to your video:

python data_preparation.py YOUR_VIDEO_PATH

The result (video_info) will be stored in the ./video_data directory.

Run with Audio File

Run the demo script with an audio file. Make sure the audio file is in .wav format with a sample rate of 16kHz and 16-bit single channel. Replace video_data/test with the path to your video_info file, video_data/audio0.wav with the path to your audio file, and 1.mp4 with the desired output video path:

python demo.py video_data/test video_data/audio0.wav 1.mp4

Real-Time Run with Microphone

For real-time operation using a microphone, simply run the following command:

python demo_avatar.py
