    Whether we can reuse the :class:`fairseq.data.EpochBatchIterator` for

    This needs to return ``False`` if the sample sizes can change across
    epochs, in which case we may need to regenerate batches at each epoch.
    If your dataset relies in ``set_epoch`` then you should consider setting
    this to ``False``.
