    Args:
        labels: tensor with labels of shape :math:`(N, *)`, where N is batch size.
          Each value is an integer representing correct classification.
        num_classes: number of classes in labels.
        device: the desired device of returned tensor.
        dtype: the desired data type of returned tensor.

    Returns:
        the labels in one hot tensor of shape :math:`(N, C, *)`,

    Examples:
        >>> labels = torch.LongTensor([[[0, 1], [2, 0]]])
        >>> one_hot(labels, num_classes=3)
        tensor([[[[1.0000e+00, 1.0000e-06],
                  [1.0000e-06, 1.0000e+00]],
        <BLANKLINE>
                 [[1.0000e-06, 1.0000e+00],
                  [1.0000e-06, 1.0000e-06]],
        <BLANKLINE>
                 [[1.0000e-06, 1.0000e-06],
                  [1.0000e+00, 1.0000e-06]]]])
