Real-Time Latent Consistency Model

This demo showcases Latent Consistency Model (LCM) using Diffusers with a MJPEG stream server. You can read more about LCM + LoRAs with diffusers here.

You need a webcam to run this demo. 🤗

Running Locally

You need CUDA and Python 3.10, Node > 19, Mac with an M1/M2/M3 chip or Intel Arc GPU

Install

python -m venv venv
source venv/bin/activate
pip3 install -r server/requirements.txt
cd frontend && npm install && npm run build && cd ..
python server/main.py --reload --pipeline img2imgSDTurbo

Don't forget to fuild the frontend!!!

cd frontend && npm install && npm run build && cd ..

Pipelines

You can build your own pipeline following examples here here,

LCM

Image to Image

python server/main.py --reload --pipeline img2img

LCM

Text to Image

python server/main.py --reload --pipeline txt2img

Image to Image ControlNet Canny

python server/main.py --reload --pipeline controlnet

LCM + LoRa

Using LCM-LoRA, giving it the super power of doing inference in as little as 4 steps. Learn more here or technical report

Image to Image ControlNet Canny LoRa

python server/main.py --reload --pipeline controlnetLoraSD15

or SDXL, note that SDXL is slower than SD15 since the inference runs on 1024x1024 images

python server/main.py --reload --pipeline controlnetLoraSDXL

Text to Image

python server/main.py --reload --pipeline txt2imgLora
python server/main.py --reload --pipeline txt2imgLoraSDXL

Setting environment variables

  • --host: Host address (default: 0.0.0.0)
  • --port: Port number (default: 7860)
  • --reload: Reload code on change
  • --max-queue-size: Maximum queue size (optional)
  • --timeout: Timeout period (optional)
  • --safety-checker: Enable Safety Checker (optional)
  • --torch-compile: Use Torch Compile
  • --use-taesd / --no-taesd: Use Tiny Autoencoder
  • --pipeline: Pipeline to use (default: "txt2img")
  • --ssl-certfile: SSL Certificate File (optional)
  • --ssl-keyfile: SSL Key File (optional)
  • --debug: Print Inference time
  • --compel: Compel option
  • --sfast: Enable Stable Fast
  • --onediff: Enable OneDiff

If you run using bash build-run.sh you can set PIPELINE variables to choose the pipeline you want to run

PIPELINE=txt2imgLoraSDXL bash build-run.sh

and setting environment variables

TIMEOUT=120 SAFETY_CHECKER=True MAX_QUEUE_SIZE=4 python server/main.py --reload --pipeline txt2imgLoraSDXL

If you're running locally and want to test it on Mobile Safari, the webserver needs to be served over HTTPS, or follow this instruction on my comment

openssl req -newkey rsa:4096 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem
python server/main.py --reload --ssl-certfile=certificate.pem --ssl-keyfile=key.pem

Docker

You need NVIDIA Container Toolkit for Docker, defaults to `controlnet``

docker build -t lcm-live .
docker run -ti -p 7860:7860 --gpus all lcm-live

reuse models data from host to avoid downloading them again, you can change ~/.cache/huggingface to any other directory, but if you use hugingface-cli locally, you can share the same cache

docker run -ti -p 7860:7860 -e HF_HOME=/data -v ~/.cache/huggingface:/data  --gpus all lcm-live

or with environment variables

docker run -ti -e PIPELINE=txt2imgLoraSDXL -p 7860:7860 --gpus all lcm-live
