1. Environment

• OS：Ubuntu 22.04 LTS
• Kernel：5.15.0-60-generic
• CPU: Intel(R) Xeon(R) Gold 6278C CPU @ 2.60GHz, 8vCPUs?
• GPU: 1 * NVIDIA V100-PCIe-32G?
• RAM: 64GB

• data disk：?2048?GiB
• Stable Diffusion WebUI version：0cc0ee1 (2023/2/20)

2. Download Stable Diffusion models

Go to?HuggingFace?or?Civitai?to find a model.

Use wget command to download the model

wget https://huggingface.co/andite/anything-v4.0/blob/main/anything-v4.5-pruned.ckpt

Here are some good models for your reference.

2.1. Realistic style models

Stable Diffusion, the original model published by CompVis and StabilityAI.

Chilloutmix

Deliberate

2.2. Anime style models

I would suggest you to start from “Anything” model if you want to draw anime artworks.

Anything

Waifu Diffusion

Hentai Diffusion

DreamShaper

OrangeMix3

3. Install Stable Diffusion WebUI

3.1. Install dependencies

1.Install proprietary Nvidia drivers in order to use CUDA. Then reboot.?

sudo apt update
sudo apt purge *nvidia*
# List available drivers for your GPU
ubuntu-drivers list
sudo apt install nvidia-driver-525

?2.Follow the instructions on?Nvidia Developers?to install CUDA. Reboot again.

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-ubuntu2204.pin
sudo mv cuda-ubuntu2204.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget https://developer.download.nvidia.com/compute/cuda/12.1.0/local_installers/cuda-repo-ubuntu2204-12-1-local_12.1.0-530.30.02-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu2204-12-1-local_12.1.0-530.30.02-1_amd64.deb
sudo cp /var/cuda-repo-ubuntu2204-12-1-local/cuda-*-keyring.gpg /usr/share/keyrings/
sudo apt-get update
sudo apt-get -y install cuda

3.Verify the installation?

nvidia-smi
nvcc --version

4.Install Python, wget, git

sudo apt install python3 python3-pip python3-virtualenv wget git

5.Because we need a Pyhon 3.6 enviroment for SD WebUi, we have to install Anaconda

wgt https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
chmod +x Miniconda3-latest-Linux-x86_64.sh
bash Miniconda3-latest-Linux-x86_64.sh
# Confirm everything and install it

6.Create a virtual environment of Python 3.10.6

conda create --name sdwebui python=3.10.6

3.2. Clone Stable Diffusion WebUI repository

1.Clone the repository of Stable Diffusion WebUI

cd ~
git clone https://github.com/AUTOMATIC1111/stable-diffusion-webui.git

2.Move?.ckpt?models to?stable-diffusion-webui

mv ~/anything-v4.5-pruned.ckpt  ~/stable-diffusion-webui/models/Stable-diffusion/

3.Enter the virtual enviroment

conda activate sdwebui

4.If you want to activate virtual environment in a bash script, add these on the top of?webui-user.sh

eval "$(conda shell.bash hook)"
conda activate sdwebui

3.3. Setup commandline arguments

According to?Wiki，we have to change some commdanline arguments in order to start SD WebUI.

Edit?webui-user.sh

vim webui-user.sh

If the VRAM of GPU is lower than 4GB, add:?COMMANDLINE_ARGS=--medvram --opt-split-attention

If your PC has RAM lower than 8GB, add:?COMMANDLINE_ARGS=--lowvram --opt-split-attention

You could also add?--listen?so you can access the WebUI from other PC on the same network. Or add?--share?to generate a public Gradio link for accessing WebUI while deploying SD WebUI to servers.

3.4. Launch Stable Diffusion WebUI

1.Run?webui.sh, it will install all the dependencies. Then a link should pop up:?http://127.0.0.1:7860?

./webui.sh

2.To access WebUI from other PC on the same network，enter?http://<IP of the PC>:7860?in the address bar of your browser. Don’t forget to open firewall port

sudo ufw allow 7860/tcp
sudo ufw reload

3.5. How to update Stable Diffusion WebUI

1.Get current branch

git rev-parse --short HEAD

2.Pull latest files

git pull

3.If something is broken after updating, roll back to the previous branch

git checkout "branch"

4. How to use Stable Diffusion WebUI

4.1. Prompts

Use “Prompts” and “Ngative Prompts” to tell AI what to draw.

See?Vodly Artist name?and?Danbooru tags?for choosing prompts.

For example, to draw Jeanne from Fate/Grand Order, we type the name of the character and characteristics of her body in the prompt fields.

jeanne d'arc from fate grand order, girl, (best quality), (masterpiece), (high detail), ((full face)), sharp, ((looking at viewer)), ((detailed pupils)), (thick thighs), (((full body))), (large breasts), vagina, nude, nipples

Then type negative prompts.

lowres, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality, normal quality, jpeg artifacts,signature, watermark, username, blurry, artist name

4.2. Text to image

1. Go to SD WebUI, type the prompts

   

2. Check?Restore faces

   

3. Clcik?Generate?butoon, it will start generate a image

   

4. You shall see the result at the right panel

   

All generated images will be stored at?stable-diffusion-webui/outputs

You can also increase the value of?Batch count?so it will generate multiple images in one run.

4.3. Imge to image

1. Type the prompts

   

2. Upload a image. Check?Restore faces. Clcik?Generate.

   

You can change the value of?CFG Scale?and?Denoising strength. The lower the value of?Denoising strength?is, the output would be more similar the original image.
