Running Automatic1111 and ComfyUI together sharing Python environment and models

How to use Automatic1111 Python virtual environment (venv) and requirements with ComfyUI.

Create a shell script in the ComfyUI root directory to activate Automatic1111 venv

Example of /ComfyUI/start.sh script

#!/bin/sh

# Modify paths as required.
PYTHON_ENV=/home/username/stable-diffusion-webui/venv/bin
COMFYUI_PATH=/home/username/ComfyUI

cd $COMFYUI_PATH
# Update ComfyUI to latest source release
git pull

# Activate venv#!/bin/sh

PYTHON_ENV=/home/username/stable-diffusion-webui/venv/bin
COMFYUI_PATH=/home/username/ComfyUI

cd $COMFYUI_PATH
git pull

. $PYTHON_ENV/activate
python3 $COMFYUI_PATH/main.py --listen

. $PYTHON_ENV/activate

# Lauch comfyui --listen makes network accessable
python3 $COMFYUI_PATH/main.py --listen

How to use existing Automatic1111 models in ComfyUI

Edit extra_model_paths.yaml located in the ComfyUI root folder.

Example of extra_model_paths.yaml contents:

a111:
    base_path: /home/username/stable-diffusion-webui/

    checkpoints: models/Stable-diffusion
    configs: models/Stable-diffusion
    vae: models/VAE
    loras: |
         models/Lora
         models/LyCORIS
    upscale_models: |
                  models/ESRGAN
                  models/RealESRGAN
                  models/SwinIR
    embeddings: embeddings
    hypernetworks: models/hypernetworks
    controlnet: models/ControlNet

How to run Automatic1111 and ComfyUI as a linux systemd service

Below is a shell script to create services for both Automatic1111 and ComfyUI.

Make sure to make changes to username and also paths to application locations in the Service One and Service Two section

#!/bin/sh
