DynaST

This is the pytorch implementation of the following ECCV 2022 paper:

DynaST: Dynamic Sparse Transformer for Exemplar-Guided Image Generation

Songhua Liu, Jingwen Ye, Sucheng Ren, and Xinchao Wang.

Installation

git clone https://github.com/Huage001/DynaST.git
cd DynaST
conda create -n DynaST python=3.6
conda activate DynaST
pip install -r requirements.txt

Inference

1. Prepare DeepFashion dataset following the instruction of CoCosNet.

2. Create a directory for checkpoints if there is not:

   mkdir -p checkpoints/deepfashion/
   

3. Download pre-trained model from here and move the file to the directory 'checkpoints/deepfashion/'.

4. Edit the file 'test_deepfashion.sh' and set the argument 'dataroot' to the root of the DeepFashion dataset.

5. Run:

   bash test_deepfashion.sh
   

6. Check the results in the directory 'checkpoints/deepfashion/test/'.

Training

1. Create a directory for the pre-trained VGG model if there is not:

   mkdir vgg
   

2. Download pre-trained VGG model used for loss computation from here and move the file to the directory 'vgg'.

3. Edit the file 'train_deepfashion.sh' and set the argument 'dataroot' to the root of the DeepFashion dataset.

4. Run:

   bash train_deepfashion.sh
   

5. Checkpoints and intermediate results are saved in the directory 'checkpoints/deepfashion/'.
