Is GridPatchDataset shuffling the patches?

[yere-qubio]

Following the example described in this notebook, are the 2D patches shuffled from epoch to epoch? I've tried shuffle=True in the DataLoader but is raises the following:

ValueError: DataLoader with IterableDataset: expected unspecified shuffle option, but got shuffle=True

If the patches are not shuffled, is there any alternative to extract 2D patches and shuffle them from epoch to epoch?
