. They are
                trained on :class:`~torchvision.datasets.FlyingChairs` +
                :class:`~torchvision.datasets.FlyingThings3D` and fine-tuned on
                Sintel. The Sintel fine-tuning step is a combination of
                :class:`~torchvision.datasets.Sintel`,
                :class:`~torchvision.datasets.KittiFlow`,
                :class:`~torchvision.datasets.HD1K`, and
                :class:`~torchvision.datasets.FlyingThings3D` (clean pass).
