-    Upload model checkpoint and config to the 🤗 Model Hub while synchronizing a local clone of the repo in

-
-    Parameters:
-        repo_path_or_name (:obj:`str`, `optional`):
-            Can either be a repository name for your model or tokenizer in the Hub or a path to a local folder (in
-            which case the repository will have the name of that local folder). If not specified, will default to
-            the name given by :obj:`repo_url` and a local directory with that name will be created.
-        repo_url (:obj:`str`, `optional`):
-            Specify this in case you want to push to an existing repository in the hub. If unspecified, a new
-            repository will be created in your namespace (unless you specify an :obj:`organization`) with
-            :obj:`repo_name`.
-        commit_message (:obj:`str`, `optional`):
-            Message to commit while pushing. Will default to :obj:`"add config"`, :obj:`"add tokenizer"` or
-            :obj:`"add model"` depending on the type of the class.
-        organization (:obj:`str`, `optional`):
-            Organization in which you want to push your model or tokenizer (you must be a member of this
-            organization).
-        private (:obj:`bool`, `optional`):
-            Whether or not the repository created should be private (requires a paying subscription).
-        api_endpoint (:obj:`str`, `optional`):
-            The API endpoint to use when pushing the model to the hub.
-        use_auth_token (:obj:`bool` or :obj:`str`, `optional`):
-            The token to use as HTTP bearer authorization for remote files. If :obj:`True`, will use the token
-            generated when running :obj:`transformers-cli login` (stored in :obj:`~/.huggingface`). Will default to
-            :obj:`True` if :obj:`repo_url` is not specified.
-        git_user (``str``, `optional`):
-            will override the ``git config user.name`` for committing and pushing files to the hub.
-        git_email (``str``, `optional`):
-            will override the ``git config user.email`` for committing and pushing files to the hub.
-        config (:obj:`dict`, `optional`):
-            Configuration object to be saved alongside the model weights.
