class_docstr: Compute the average `Hamming distance`_ (also known as Hamming loss) for multilabel tasks.
  
  .. math::
      \text{Hamming distance} = \frac{1}{N \cdot L} \sum_i^N \sum_l^L 1(y_{il} \neq \hat{y}_{il})
  
  Where :math:`y` is a tensor of target values, :math:`\hat{y}` is a tensor of predictions,
  and :math:`\bullet_{il}` refers to the :math:`l`-th label of the :math:`i`-th sample of that
  tensor.
  
  As input to ``forward`` and ``update`` the metric accepts the following input:
  
  - ``preds`` (:class:`~torch.Tensor`): An int tensor or float tensor of shape ``(N, C, ...)``. If preds is a
    floating point tensor with values outside [0,1] range we consider the input to be logits and will auto
    apply sigmoid per element. Additionally, we convert to int tensor with thresholding using the value in
    ``threshold``.
  - ``target`` (:class:`~torch.Tensor`): An int tensor of shape ``(N, C, ...)``.
  
  As output to ``forward`` and ``compute`` the metric returns the following output:
  
  - ``mlhd`` (:class:`~torch.Tensor`): A tensor whose returned shape depends on the ``average`` and
    ``multidim_average`` arguments:
  
      - If ``multidim_average`` is set to ``global``:
  
        - If ``average='micro'/'macro'/'weighted'``, the output will be a scalar tensor
        - If ``average=None/'none'``, the shape will be ``(C,)``
  
      - If ``multidim_average`` is set to ``samplewise``:
  
        - If ``average='micro'/'macro'/'weighted'``, the shape will be ``(N,)``
        - If ``average=None/'none'``, the shape will be ``(N, C)``
  
  If ``multidim_average`` is set to ``samplewise`` we expect at least one additional dimension ``...`` to be present,
  which the reduction will then be applied over instead of the sample dimension ``N``.
  
  Args:
      num_labels: Integer specifying the number of labels
      threshold: Threshold for transforming probability to binary (0,1) predictions
      average:
          Defines the reduction that is applied over labels. Should be one of the following:
  
          - ``micro``: Sum statistics over all labels
          - ``macro``: Calculate statistics for each label and average them
          - ``weighted``: calculates statistics for each label and computes weighted average using their support
          - ``"none"`` or ``None``: calculates statistic for each label and applies no reduction
  
      multidim_average:
          Defines how additionally dimensions ``...`` should be handled. Should be one of the following:
  
          - ``global``: Additional dimensions are flatted along the batch dimension
          - ``samplewise``: Statistic will be calculated independently for each sample on the ``N`` axis.
            The statistics in this case are calculated over the additional dimensions.
  
      ignore_index:
          Specifies a target value that is ignored and does not contribute to the metric calculation
      validate_args: bool indicating if input arguments and tensors should be validated for correctness.
          Set to ``False`` for faster computations.
  
  Example (preds is int tensor):
      >>> from torch import tensor
      >>> from torchmetrics.classification import MultilabelHammingDistance
      >>> target = tensor([[0, 1, 0], [1, 0, 1]])
      >>> preds = tensor([[0, 0, 1], [1, 0, 1]])
      >>> metric = MultilabelHammingDistance(num_labels=3)
      >>> metric(preds, target)
      tensor(0.3333)
      >>> mlhd = MultilabelHammingDistance(num_labels=3, average=None)
      >>> mlhd(preds, target)
      tensor([0.0000, 0.5000, 0.5000])
  
  Example (preds is float tensor):
      >>> from torchmetrics.classification import MultilabelHammingDistance
      >>> target = tensor([[0, 1, 0], [1, 0, 1]])
      >>> preds = tensor([[0.11, 0.22, 0.84], [0.73, 0.33, 0.92]])
      >>> metric = MultilabelHammingDistance(num_labels=3)
      >>> metric(preds, target)
      tensor(0.3333)
      >>> mlhd = MultilabelHammingDistance(num_labels=3, average=None)
      >>> mlhd(preds, target)
      tensor([0.0000, 0.5000, 0.5000])
  
  Example (multidim tensors):
      >>> from torchmetrics.classification import MultilabelHammingDistance
      >>> target = tensor([[[0, 1], [1, 0], [0, 1]], [[1, 1], [0, 0], [1, 0]]])
      >>> preds = tensor([[[0.59, 0.91], [0.91, 0.99], [0.63, 0.04]],
      ...                 [[0.38, 0.04], [0.86, 0.780], [0.45, 0.37]]])
      >>> metric = MultilabelHammingDistance(num_labels=3, multidim_average='samplewise')
      >>> metric(preds, target)
      tensor([0.6667, 0.8333])
      >>> mlhd = MultilabelHammingDistance(num_labels=3, multidim_average='samplewise', average=None)
      >>> mlhd(preds, target)
      tensor([[0.5000, 0.5000, 1.0000],
              [1.0000, 1.0000, 0.5000]])
