A Mixin containing the functionality to push an object to the hub.
This is similar to huggingface_hub.ModelHubMixin but is lighter and makes less assumptions about its
subclasses (in particular, the fact that it's not necessarily a model).
The inheriting classes must implement '_save_pretrained' and 'from_pretrained'.

Save object in local directory.
Args:
save_directory (`str` or `Path`):
Path to directory in which the object will be saved.
push_to_hub (`bool`, *optional*, defaults to `False`):
Whether or not to push your object to the Huggingface Hub after saving it.

ID of your repository on the Hub. Used only if `push_to_hub=True`. Will default to the folder name if
not provided.

Additional arguments passed to the card template to customize the card.

Download the object from the Huggingface Hub and instantiate it.

pretrained_name_or_path (`str`, `Path`):
- Either the `repo_id` (string) of the object hosted on the Hub, e.g. `lerobot/diffusion_pusht`.
- Or a path to a `directory` containing the object files saved using `.save_pretrained`,
e.g., `../path/to/my_model_directory/`.
revision (`str`, *optional*):
Revision on the Hub. Can be a branch name, a git tag or any commit id.
Defaults to the latest commit on `main` branch.
force_download (`bool`, *optional*, defaults to `False`):
Whether to force (re-)downloading the files from the Hub, overriding the existing cache.
proxies (`Dict[str, str]`, *optional*):
A dictionary of proxy servers to use by protocol or endpoint, e.g., `{'http': 'foo.bar:3128',
'http://hostname': 'foo.bar:4012'}`. The proxies are used on every request.
token (`str` or `bool`, *optional*):
The token to use as HTTP bearer authorization for remote files. By default, it will use the token
cached when running `huggingface-cli login`.
cache_dir (`str`, `Path`, *optional*):
Path to the folder where cached files are stored.
local_files_only (`bool`, *optional*, defaults to `False`):
If `True`, avoid downloading the file and return the path to the local cached file if it exists.
kwargs (`Dict`, *optional*):
Additional kwargs to pass to the object during initialization.
