(2023-09-12) Add Gradio demo.

(2023-09-11) Upload pre-trained models.

(2023-09-07) Upload source codes.

• Clone this repository:

git clone https://github.com/yangxy/PASD.git
cd PASD

• Download SD1.5 models from huggingface and put them into checkpoints/stable-diffusion-v1-5.

• Prepare training datasets. Please check dataloader/localdataset.py and dataloader/webdataset.py carefully and set the paths correctly. We highly recommend to use dataloader/webdataset.py.

• Train a PASD.

bash ./train_pasd.sh

if you want to train pasd_light, use --use_pasd_light.

• Test PASD.

Download our pre-trained models pasd | pasd_rrdb | pasd_light | pasd_light_rrdb, and put them into runs/.

python test_pasd.py # --use_pasd_light --use_personalized_model

Please read the arguments in test_pasd.py carefully. We adopt the tiled vae method proposed by multidiffusion-upscaler-for-automatic1111 to save GPU memory.

Please try --use_personalized_model for personalized stylizetion, old photo restoration and real-world SR. Set --conditioning_scale for different stylized strength.

We use personalized models including majicMIX realistic(for SR and restoration), ToonYou(for stylization) and modern disney style(unet only, for stylization). You can download more from communities and put them into checkpoints/personalized_models.

If the default setting does not yield good results, try different --pasd_model_path, --seed, --prompt, --upscale, or --high_level_info to get better performance.

• Gradio Demo
