LECO ✏️
Low-rank adaptation for Erasing COncepts from diffusion models.
The original repository: Erasing Concepts from Diffusion Models
and the project page: https://erasing.baulab.info/
(Not only for erasing concepts, but also emphasizing or swapping them by devising prompts and LoRA weight. See ConceptMod for more details)
Setup
conda create -n leco python=3.10
pip install torch torchvision --index-url https://download.pytorch.org/whl/cu118
pip install xformers
pip install -r requirements.txtTrain
You need 8GB VRAM at least.

Pretrained weights
You can use the pretrained weights on AUTOMATIC1111's webui.
