Installation

Clone this repo.

git clone https://github.com/KumapowerLIU/PD-GAN.git

Prerequisites

• Python3
• Pytorch >=1.0
• Tensorboard
• Torchvision
• pillow
• loguru

Dataset Preparation

We use Places2, CelebA and Paris Street-View datasets. To train a model on the full dataset, download datasets from official websites.

Our model is trained on the irregular mask dataset provided by Liu et al. You can download the publically available Irregular Mask Dataset from their website.

Code Structure

• train.py: the entry point for training.
• train.py: the entry point for test.
• models/PConv.py: defines the loss, model, optimizetion, foward, backward and others of Partial Conv.
• models/PDGAN.py: defines the loss, model, optimizetion, foward, backward and others of PDGAN.
• models/network/pcconv.py: defines the network of Partial Conv.
• models/network/pdgan.py: defines the network of PDGAN.
• config/: creates option lists using argparse package. More individuals are dynamically added in other files as well.
• data/: process the dataset before passing to the network.

Training New Models

# To train on the you dataset for ParitalConv, for example.
python train.py --gt_root [the path of structure images]   --mask_root [the path of mask images] --model PConv

# To train on the you dataset for PDGAN, for example.
python train.py --gt_root [the path of structure images]   --mask_root [the path of mask images] --model PDGAN --pre_ckpt_PConv_EN_dir [the path of pre-trained PartialConv encoder] --pre_ckpt_PConv_DE_dir [the path of pre-trained PartialConv decoder]

There are many options you can specify. Please use python train.py --help or see the options To log training, use --./logs for Tensorboard. The logs are stored at logs/[name].

Pre-trained weights and test model

There are three folders to present a pre-trained model for three datasets, respectively. Currently, we only upload the pre-trained model of Partical Conv. in each folder. We implement the Partial Conv by ourselves.

TODO

• upload the test code
• upload the pre-trained model of PDGAN.
