Dataset

We use PACS, Office-Home Dataset. Dataset Structure is provided below.
We split examples from training domains in the ratio 8:2 (train:validation)
Please prepare following this structure.

If you want to split dataset, you can refer to our code (utils.py - split_domain_data function)

Requirements & Environment

we used one RTX 3090 GPU for model training. and we also tested V100 GPU and A6000 GPU.

pip install -r requirements.txt

In particular, ensure that the version of Pytorch 1.7+, python 3.8+, cuda 11.0+

Train

Run the following command to train the DG colorization Model

python train.py --config CONFIG --save_dir SAVE_DIR --w-adv [coefficient of adv loss] --gpu [gpu number]

Test

Run the following comman to test the model

python test.py --h_model_path [head encoder model.pth] --t_model_path [tail encoder model.pth] --d_model_path [decoder model.pth] \
               --source [source domain name] --domain [target domain name] \
               --data_dir [testset root] --save_dir  [path to save] \
               --gpu [gpu number]

Dataset Structure is provided below. Please input dataset root path in 'data_dir' argument.
