This repository contains training, generation and utility scripts for Stable Diffusion.

Updates

• 15 Jan. 2023, 2023/1/15
  • Added --max_train_epochs and --max_data_loader_n_workers option for each training script.
  • If you specify the number of training epochs with --max_train_epochs, the number of steps is calculated from the number of epochs automatically.
  • You can set the number of workers for DataLoader with --max_data_loader_n_workers, default is 8. The lower number may reduce the main memory usage and the time between epochs, but may cause slower dataloading (training).
  • --max_train_epochs と --max_data_loader_n_workers のオプションが学習スクリプトに追加されました。
  • --max_train_epochs で学習したいエポック数を指定すると、必要なステップ数が自動的に計算され設定されます。
  • --max_data_loader_n_workers で DataLoader の worker 数が指定できます（デフォルトは8）。値を小さくするとメインメモリの使用量が減り、エポック間の待ち時間も短くなるようです。ただしデータ読み込み（学習時間）は長くなる可能性があります。

日本語版README

For easier use (GUI and PowerShell scripts etc...), please visit the repository maintained by bmaltais. Thanks to @bmaltais!

This repository contains the scripts for:

• DreamBooth training, including U-Net and Text Encoder
• fine-tuning (native training), including U-Net and Text Encoder
• LoRA training
• image generation
• model conversion (supports 1.x and 2.x, Stable Diffision ckpt/safetensors and Diffusers)

About requirements.txt

These files do not contain requirements for PyTorch. Because the versions of them depend on your environment. Please install PyTorch at first (see installation guide below.)

The scripts are tested with PyTorch 1.12.1 and 1.13.0, Diffusers 0.10.2.

Windows Required Dependencies

Python 3.10.6 and Git:

• Python 3.10.6: https://www.python.org/ftp/python/3.10.6/python-3.10.6-amd64.exe
• git: https://git-scm.com/download/win

Give unrestricted script access to powershell so venv can work:

• Open an administrator powershell window
• Type Set-ExecutionPolicy Unrestricted and answer A
• Close admin powershell window

Windows Installation

Open a regular Powershell terminal and type the following inside:

git clone https://github.com/kohya-ss/sd-scripts.git
cd sd-scripts

python -m venv --system-site-packages venv
.\venv\Scripts\activate

pip install torch==1.12.1+cu116 torchvision==0.13.1+cu116 --extra-index-url https://download.pytorch.org/whl/cu116
pip install --upgrade -r requirements.txt
pip install -U -I --no-deps https://github.com/C43H66N12O12S2/stable-diffusion-webui/releases/download/f/xformers-0.0.14.dev0-cp310-cp310-win_amd64.whl

cp .\bitsandbytes_windows\*.dll .\venv\Lib\site-packages\bitsandbytes\
cp .\bitsandbytes_windows\cextension.py .\venv\Lib\site-packages\bitsandbytes\cextension.py
cp .\bitsandbytes_windows\main.py .\venv\Lib\site-packages\bitsandbytes\cuda_setup\main.py

accelerate config

Answers to accelerate config:

- This machine
- No distributed training
- NO
- NO
- NO
- all
- fp16

note: Some user reports ValueError: fp16 mixed precision requires a GPU is occured in training. In this case, answer 0 for the 6th question: What GPU(s) (by id) should be used for training on this machine as a comma-seperated list? [all]:

(Single GPU with id 0 will be used.)

Upgrade

When a new release comes out you can upgrade your repo with the following command:

cd sd-scripts
git pull
.\venv\Scripts\activate
pip install --upgrade -r requirements.txt

Once the commands have completed successfully you should be ready to use the new version.
