InstantX / CSGO

Introduction 📖

This repo, named CSGO , contains the official PyTorch implementation of our paper CSGO: Content-Style Composition in Text-to-Image Generation . We are actively updating and improving this repository. If you find any bugs or have suggestions, welcome to raise issues or submit pull requests (PR) 💖.

Detail ✨

We currently release two model weights.

Pipeline 💻

Capabilities 🚅

🔥 Our CSGO achieves image-driven style transfer, text-driven stylized synthesis, and text editing-driven stylized synthesis .

Getting Started 🏁

1. Clone the code and prepare the environment

git clone https://github.com/instantX-research/CSGO
cd CSGO

# create env using conda
conda create -n CSGO python=3.9
conda activate CSGO

# install dependencies with pip
# for Linux and Windows users
pip install -r requirements.txt

2. Download pretrained weights(coming soon)

The easiest way to download the pretrained weights is from HuggingFace:

# first, ensure git-lfs is installed, see: https://docs.github.com/en/repositories/working-with-files/managing-large-files/installing-git-large-file-storage
git lfs install
# clone and move the weights
git clone https://huggingface.co/InstanX/CSGO CSGO

Our method is fully compatible with SDXL , VAE , ControlNet , and Image Encoder . Please download them and place them in the ./base_models folder.

tips:If you expect to load Controlnet directly using ControlNetPipeline as in CSGO, do the following:

git clone https://huggingface.co/TTPlanet/TTPLanet_SDXL_Controlnet_Tile_Realistic
mv TTPLanet_SDXL_Controlnet_Tile_Realistic/TTPLANET_Controlnet_Tile_realistic_v2_fp16.safetensors TTPLanet_SDXL_Controlnet_Tile_Realistic/diffusion_pytorch_model.safetensors
