• Environment

  • Python 3.6

  • TensorFlow 2.2, TensorFlow Addons 0.10.0

  • OpenCV, scikit-image, tqdm, oyaml

  • we recommendAnaconda orMiniconda, then you can create the TensorFlow 2.2 environment with commands below

    conda create -n tensorflow-2.2 python=3.6source activate tensorflow-2.2conda install scikit-image tqdm tensorflow-gpu=2.2conda install -c conda-forge oyamlpip install tensorflow-addons==0.10.0

  • NOTICE: if you create a new conda environment, remember to activate it before any other command

    source activate tensorflow-2.2

• Dataset

  • download the summer2winter dataset

    sh ./download_dataset.sh summer2winter_yosemite

  • download the horse2zebra dataset

    sh ./download_dataset.sh horse2zebra

  • seedownload_dataset.sh for more datasets

• Example of training

  CUDA_VISIBLE_DEVICES=0 python train.py --dataset summer2winter_yosemite

  • tensorboard for loss visualization

    tensorboard --logdir ./output/summer2winter_yosemite/summaries --port 6006

• Example of testing
