How To Use

1. --cuda_device=0: It is device selection in case of multiple GPU. If you have only one GPU, just set it to 0.
2. --input_path, --output_path, --restore_path: you have to change 'your_directory' part in each argument to suit your environment.
3. After modifying above three arguemtns, run the following commands for each Track. Then, the result images will be created. (ex, challenge\experiments\Track1\results)

Track 1:

python get_sr.py --model=mdsr_mod5 --restore_path=your_directory\challenge\experiments\Track_1\model_200000.pth --input_path=your_directory\challenge\data\TestLRX2\TestLR --scale=2 --edsr_res_blocks=80 --output_path=your_directory\challenge\experiments\Track_1\results --cuda_device=0 --chop_forward

Track 2:

python get_sr.py --model=mdsr_mod5 --restore_path=your_directory\challenge\experiments\Track_2\model_200000.pth --input_path=your_directory\challenge\data\TestLRX3\TestLR --scale=3 --edsr_res_blocks=80 --output_path=your_directory\challenge\experiments\Track_2\results --cuda_device=0 --self_ensemble --chop_forward

Track 3:

python get_sr.py --model=mdsr_mod5 --restore_path=your_directory\challenge\experiments\Track_3\model_200000.pth --input_path=your_directory\challenge\data\TestLRX4\TestLR --scale=4 --edsr_res_blocks=80 --output_path=your_directory\challenge\experiments\Track_3\results --cuda_device=0 --self_ensemble --chop_forward
