StyleDrop

Huggingface

This is an unofficial PyTorch implementation of StyleDrop: Text-to-Image Generation in Any Style.

Unlike the parameters in the paper in (Round 1), we set $\lambda_A=2.0$, $\lambda_B=5.0$ and d_prj=32, is_shared=False, which we found work better, these hyperparameters can be seen in configs/custom.py.

we release them to facilitate community research.

News

  • [07/06/2023] Online Gradio Demo is available here

Todo List

  • Release the code.
  • Add gradio inference demo (runs in local).
  • Add iterative training (Round 2).

Data & Weights Preparation

First, download VQGAN from this link (from MAGE, thanks!), and put the downloaded VQGAN in assets/vqgan_jax_strongaug.ckpt.

Then, download the pre-trained checkpoints from this link to assets/ckpts for evaluation or to continue training for more iterations.

finally, prepare empty_feature by runnig command python extract_empty_feature.py

And the final directory structure is as follows:

.
├── assets
│   ├── ckpts
│   │   ├── cc3m-285000.ckpt
│   │   │   ├── lr_scheduler.pth
│   │   │   ├── nnet_ema.pth
│   │   │   ├── nnet.pth
│   │   │   ├── optimizer.pth
│   │   │   └── step.pth
│   │   └── imagenet256-450000.ckpt
│   │       ├── lr_scheduler.pth
│   │       ├── nnet_ema.pth
│   │       ├── nnet.pth
│   │       ├── optimizer.pth
│   │       └── step.pth
│   ├── fid_stats
│   │   ├── fid_stats_cc3m_val.npz
│   │   └── fid_stats_imagenet256_guided_diffusion.npz
│   ├── pipeline.png
|   ├── contexts
│   │   └── empty_context.npy
└── └── vqgan_jax_strongaug.ckpt

Dependencies

Same as MUSE-PyTorch.

conda install pytorch torchvision torchaudio cudatoolkit=11.3
pip install accelerate==0.12.0 absl-py ml_collections einops wandb ftfy==6.1.1 transformers==4.23.1 loguru webdataset==0.2.5 gradio

Train

All style data in the paper are placed in the data directory

  1. Modify data/one_style.json (It should be noted that one_style.json and style data must be in the same directory), The format is file_name:[object,style]
{"image_03_05.jpg":["A bear","in kid crayon drawing style"]}
  1. Training script as follows.
#!/bin/bash
unset EVAL_CKPT
unset ADAPTER
export OUTPUT_DIR="output_dir/for/this/experiment"
accelerate launch --num_processes 8 --mixed_precision fp16 train_t2i_custom_v2.py --config=configs/custom.py

Inference

The pretrained style_adapter weights can be downloaded from 🤗 Hugging Face.

#!/bin/bash
export EVAL_CKPT="assets/ckpts/cc3m-285000.ckpt" 
export ADAPTER="path/to/your/style_adapter"

export OUTPUT_DIR="output/for/this/experiment"

accelerate launch --num_processes 8 --mixed_precision fp16 train_t2i_custom_v2.py --config=configs/custom.py

Gradio Demo

Put the style_adapter weights in ./style_adapter folder and run the following command will launch the demo:

python gradio_demo.py

The demo is also hosted on HuggingFace.
