"""Script for running the keypoint-to-UV network and saving the predicted UVs.

Example:
    python run_kp2uv.py --model kp2uv --dataroot ./datasets/reflection --results_dir ./datasets/reflection

It will load the pre-trained model from '--checkpoints_dir' and save the results to '--results_dir'.

See options/base_options.py and options/test_options.py for more test options.
