# HOWTO

This repo provide all the required config to run the Dreambooth version found in this note: https://note.com/kohya_ss/n/nee3ed1649fb6


## 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

## Installation

Open a Powershell terminal and type the following inside:

```powershell
git clone https://github.com/bmaltais/kohya_ss.git
cd kohya_ss
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 diffusers
pip install -r requirements.txt
pip install OmegaConf
pip install pytorch_lightning

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

# Setup bitsandbytes with Adam8bit support for windows: https://note.com/kohya_ss/n/n47f654dc161e
pip install bitsandbytes==0.35.0
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

## Folders configuration

Refer to the note to understand how to create the folde structure. In short it should look like:

```
<wathever top folder name>
|- reg_<class>
    |- <repeat count>_<prompt>
|- train_<class>
   |- <repeat count>_<prompt>
```

Example for `sks dog`

```
my_sks_dog_dreambooth
|- reg_dog
    |- 1_sks dog
|- train_dog
    |- 20_sks dog
```

## Execution

Edit and paste the following in a Powershell terminal:

```powershell
