      Load a model from a github repo or a local directory.
  
      Note: Loading a model is the typical use case, but this can also be used to
      for loading other objects such as tokenizers, loss functions, etc.
  
      If ``source`` is 'github', ``repo_or_dir`` is expected to be
      of the form ``repo_owner/repo_name[:ref]`` with an optional
      ref (a tag or a branch).
  
      If ``source`` is 'local', ``repo_or_dir`` is expected to be a
      path to a local directory.
  
      Args:
          repo_or_dir (str): If ``source`` is 'github',
              this should correspond to a github repo with format ``repo_owner/repo_name[:ref]`` with
              an optional ref (tag or branch), for example 'pytorch/vision:0.10'. If ``ref`` is not specified,
              the default branch is assumed to be ``main`` if it exists, and otherwise ``master``.
              If ``source`` is 'local'  then it should be a path to a local directory.
          model (str): the name of a callable (entrypoint) defined in the
              repo/dir's ``hubconf.py``.
          *args (optional): the corresponding args for callable ``model``.
          source (str, optional): 'github' or 'local'. Specifies how
              ``repo_or_dir`` is to be interpreted. Default is 'github'.
          trust_repo (bool, str or None): ``"check"``, ``True``, ``False`` or ``None``.
              This parameter was introduced in v1.12 and helps ensuring that users
              only run code from repos that they trust.
  
              - If ``False``, a prompt will ask the user whether the repo should
                be trusted.
              - If ``True``, the repo will be added to the trusted list and loaded
                without requiring explicit confirmation.
              - If ``"check"``, the repo will be checked against the list of
                trusted repos in the cache. If it is not present in that list, the
                behaviour will fall back onto the ``trust_repo=False`` option.
              - If ``None``: this will raise a warning, inviting the user to set
                ``trust_repo`` to either ``False``, ``True`` or ``"check"``. This
                is only present for backward compatibility and will be removed in
                v2.0.
  
              Default is ``None`` and will eventually change to ``"check"`` in v2.0.
          force_reload (bool, optional): whether to force a fresh download of
              the github repo unconditionally. Does not have any effect if
              ``source = 'local'``. Default is ``False``.
          verbose (bool, optional): If ``False``, mute messages about hitting
              local caches. Note that the message about first download cannot be
              muted. Does not have any effect if ``source = 'local'``.
              Default is ``True``.
          skip_validation (bool, optional): if ``False``, torchhub will check that the branch or commit
              specified by the ``github`` argument properly belongs to the repo owner. This will make
              requests to the GitHub API; you can specify a non-default GitHub token by setting the
              ``GITHUB_TOKEN`` environment variable. Default is ``False``.
          **kwargs (optional): the corresponding kwargs for callable ``model``.
  
      Returns:
          The output of the ``model`` callable when called with the given
          ``*args`` and ``**kwargs``.
  
      Example:
          >>> # xdoctest: +REQUIRES(env:TORCH_DOCTEST_HUB)
          >>> # from a github repo
          >>> repo = 'pytorch/vision'
          >>> model = torch.hub.load(repo, 'resnet50', weights='ResNet50_Weights.IMAGENET1K_V1')
          >>> # from a local directory
          >>> path = '/some/local/path/pytorch/vision'
          >>> # xdoctest: +SKIP
          >>> model = torch.hub.load(path, 'resnet50', weights='ResNet50_Weights.DEFAULT')
