Prerequisites

• Linux, macOS or Windows
• Python 2 or 3
• CPU or NVIDIA GPU + CUDA CuDNN

Getting Started

Downloading Datasets

Please refer to datasets.md for details.

Installation

• Clone this repo:

git clone https://github.com/giddyyupp/ganilla.git
cd ganilla

• Install PyTorch 0.4+ and torchvision from http://pytorch.org and other dependencies (e.g., visdom and dominate). You can install all the dependencies by

pip install -r requirements.txt

• For Conda users, we include a script ./scripts/conda_deps.sh to install PyTorch and other libraries.

GANILLA train/test

• Download a GANILLA/CycleGAN dataset (e.g. maps):

bash ./datasets/download_cyclegan_dataset.sh maps

• Train a model:

#!./scripts/train_ganilla.sh
python train.py --dataroot ./datasets/maps --name maps_cyclegan --model cycle_gan --netG resnet_fpn

• To view training results and loss plots, run python -m visdom.server and click the URL http://localhost:8097. To see more intermediate results, check out ./checkpoints/maps_cyclegan/web/index.html
• Test the model:

#!./scripts/test_cyclegan.sh
python test.py --dataroot ./datasets/maps --name maps_cyclegan --model cycle_gan --netG resnet_fpn

The test results will be saved to a html file here: ./results/maps_cyclegan/latest_test/index.html.

You can find more scripts at scripts directory.

Apply a pre-trained model (GANILLA)

• You can download pretrained models using following link

Put a pretrained model under ./checkpoints/{name}_pretrained/100_net_G.pth.

• To test the model, you also need to download the monet2photo dataset and use trainB images as source:

bash ./datasets/download_cyclegan_dataset.sh monet2photo

• Then generate the results using

python test.py --dataroot datasets/monet2photo/testB --name {name}_pretrained --model test

The option --model test is used for generating results of GANILLA only for one side. python test.py --model cycle_gan will require loading and generating results in both directions, which is sometimes unnecessary. The results will be saved at ./results/. Use --results_dir {directory_path_to_save_result} to specify the results directory.

• If you would like to apply a pre-trained model to a collection of input images (rather than image pairs), please use --dataset_mode single and --model test options. Here is a script to apply a model to Facade label maps (stored in the directory facades/testB).

#!./scripts/test_single.sh
python test.py --dataroot ./datasets/monet2photo/testB/ --name {your_trained_model_name} --model test

You might want to specify --netG to match the generator architecture of the trained model.

Style & Content CNN

We shared style & content CNNs in this repo. It contains train/test procedure as well as pretrained weights for both cnns.
