AnomalyDatasetArguments dataclass

Anomaly dataset arguments.

Parameters:

  • train_samples (int) –

    number of train samples

  • val_samples (tuple[int, int]) –

    number of validation samples (good, bad)

  • test_samples (tuple[int, int]) –

    number of test samples (good, bad)

anomaly_dataset(tmp_path, dataset_arguments)

Fixture used to dinamically generate anomaly dataset. By default images are random grayscales with size 10x10.
