1. Create the Python environment using conda from requirements.txt:

   $ conda create -n pytorch_dorpatch --file requirements.txt -c pytorch -c nvidia

   and switch to the environment by

   $ conda activate pytorch_dorpatch

2. Prepare the dataset and pre-trained model.

   • Download the corresponding dataset (e.g., download the validation set of ImageNet from here) and prepare the data to the directory $dataset_directory, where $dataset_directory is a variable referring to the path that will store all datasets (e.g., if $dataset_directory = './data', then the resulting validation set of ImageNet is prepared to the directory './data/imagenet/val').

   • Download the corresponding pretrained model (e.g., 'resnetv2_50x1_bit_distilled_cutout2_128_imagenet.pth' for ImageNet from here, provided by PatchCleanser) and put it into "pretrained_models/$dataset/", where $dataset is a variable referring to the directory name of the corresponding dataset (e.g., $dataset = 'imagenet' for the ImageNet model dataset to match the above directory name of the ImageNet dataset in $dataset_directory).

3. Run the code with $ python main.py --data_dir $dataset_directory
