CartoonGAN-Test-Pytorch-Torch

Pytorch and Torch testing code of CartoonGAN [Chen et al., CVPR18]. With the released pretrained models by the authors, I made these simple scripts for a quick test.

Getting started

• Linux
• NVIDIA GPU
• Pytorch 0.3

• Torch

  git clone https://github.com/Yijunmaverick/CartoonGAN-Test-Pytorch-Torch
  cd CartoonGAN-Test-Pytorch-Torch
  

Pytorch

The original pretrained models are Torch nngraph models, which cannot be loaded in Pytorch through load_lua. So I manually copy the weights (bias) layer by layer and convert them to .pth models.

• Download the converted models:

  sh pretrained_model/download_pth.sh
  

• For testing:

  python test.py --input_dir YourImgDir --style Hosoda --gpu 0
  

Torch

Working with the original models in Torch is also fine. I just convert the weights (bias) in their models from CudaTensor to FloatTensor so that cudnn is not required for loading models.

• Download the converted models:

  sh pretrained_model/download_t7.sh
  

• For testing:

  th test.lua -input_dir YourImgDir -style Hosoda -gpu 0
  

Examples (Left: input, Right: output)

Note

• The training code should be similar to the popular GAN-based image-translation frameworks and thus is not included here.
