From https://github.com/sashaok123/LoRA-EXTRACTOR
I can't execute the LoRA-EXTRACTOR from the original source, so I made some modifications
install Python 3.10.6
download this library
Execute cmd on file path and execute the following command
pip install virtualenv
virtualenv venv
venv\Scripts\activate.bat
pip install -r requirements.txt
Run LoRA extraction only as system administrator
