MVTecAD

A Pytorch loader for MVTecAD dataset.

It strictly follows the code style of common Pytorch datasets, such as torchvision.datasets.CIFAR10. Therefore, there is no need to worry about the consistence of your code !!!

Showcase

from torch.utils.data import DataLoader
from torchvision import transforms
from mvtec_ad import MVTecAD


def _convert_label(x):
    '''
    convert anomaly label. 0: normal; 1: anomaly.
    :param x (int): class label
    :return: 0 or 1
    '''
    return 0 if x == 0 else 1

if __name__ == '__main__':

    # define transforms
    transform = transforms.Compose([transforms.Resize((300, 300)), transforms.ToTensor()])
    target_transform = transforms.Lambda(_convert_label)

    # load data
    mvtec = MVTecAD('data',
                    subset_name='bottle',
                    train=True,
                    transform=transform,
                    mask_transform=transform,
                    target_transform=target_transform,
                    download=True)

    # feed to data loader
    data_loader = DataLoader(mvtec,
                             batch_size=2,
                             shuffle=True,
                             num_workers=8,
                             pin_memory=True,
                             drop_last=True)

    # obtain in batch
    for idx, (image, mask, target) in enumerate(data_loader):
        print(idx, target)
