# Real-Time Latent Consistency Model

This demo showcases [Latent Consistency Model (LCM)](https://huggingface.co./SimianLuo/LCM_Dreamshaper_v7) using [Diffusers](https://github.com/huggingface/diffusers/tree/main/examples/community#latent-consistency-pipeline) with a MJPEG stream server.

You need a webcam to run this demo. 🤗

See a collecting with live demos [here](https://huggingface.co./collections/latent-consistency/latent-consistency-model-demos-654e90c52adb0688a0acbe6f)

## Running Locally

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

`TIMEOUT`: limit user session timeout  
`SAFETY_CHECKER`: disabled if you want NSFW filter off  
`MAX_QUEUE_SIZE`: limit number of users on current app instance  
`TORCH_COMPILE`: enable if you want to use torch compile for faster inference works well on A100 GPUs


## Install

```bash
python -m venv venv
source venv/bin/activate
pip3 install -r requirements.txt
```

# LCM
### Image to Image

```bash
uvicorn "app-img2img:app" --host 0.0.0.0 --port 7860 --reload
```

### Image to Image ControlNet Canny

Based pipeline from [taabata](https://github.com/taabata/LCM_Inpaint_Outpaint_Comfy)

```bash
uvicorn "app-controlnet:app" --host 0.0.0.0 --port 7860 --reload
```

### Text to Image

```bash
uvicorn "app-txt2img:app" --host 0.0.0.0 --port 7860 --reload
```

# LCM + LoRa

Using LCM-LoRA, giving it the super power of doing inference in as little as 4 steps. [Learn more here](https://huggingface.co./blog/lcm_lora) or [technical report](https://huggingface.co./papers/2311.05556)



### Image to Image ControlNet Canny LoRa


```bash
uvicorn "app-controlnetlora:app" --host 0.0.0.0 --port 7860 --reload
```

### Text to Image

```bash
uvicorn "app-txt2imglora:app" --host 0.0.0.0 --port 7860 --reload
```


### Setting environment variables

```bash
TIMEOUT=120 SAFETY_CHECKER=True MAX_QUEUE_SIZE=4 uvicorn "app-img2img:app" --host 0.0.0.0 --port 7860 --reload
```

If you're running locally and want to test it on Mobile Safari, the webserver needs to be served over HTTPS.

```bash
openssl req -newkey rsa:4096 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem
uvicorn "app-img2img:app" --host 0.0.0.0 --port 7860 --reload --log-level info --ssl-certfile=certificate.pem --ssl-keyfile=key.pem
```

## Docker

You need NVIDIA Container Toolkit for Docker

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

or with environment variables

```bash
docker run -ti -e TIMEOUT=0 -e SAFETY_CHECKER=False -p 7860:7860 --gpus all lcm-live
```
