"""
Upload model checkpoint and config to the 🤗 Model Hub while synchronizing a local clone of the repo in
:obj:`repo_path_or_name`.
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.
Returns:
The url of the commit of your model in the given repository.
