로그인

####
huggingface_hub.login

< source >

( token: Optional = None add_to_git_credential: bool = False new_session: bool = True write_permission: bool = False )

Parameters

- token (`str`, optional) — User access token to generate from https://huggingface.co/settings/token.
- add_to_git_credential (`bool`, defaults to `False`) — If `True`, token will be set as git credential. If no git credential helper is configured, a warning will be displayed to the user. If `token` is `None`, the value of `add_to_git_credential` is ignored and will be prompted again to the end user.
- new_session (`bool`, defaults to `True`) — If `True`, will request a token even if one is already saved on the machine.
- write_permission (`bool`) — Ignored and deprecated argument.

Raises

`ValueError` or `ImportError`

- `ValueError` — If an organization token is passed. Only personal account tokens are valid to log in.
- `ValueError` — If token is invalid.
- `ImportError` — If running in a notebook but `ipywidgets` is not installed.

Login the machine to access the Hub.

The `token` is persisted in cache and set as a git credential. Once done, the machine is logged in and the access token will be available across all `huggingface_hub` components. If `token` is not provided, it will be prompted to the user either with a widget (in a notebook) or via the terminal.

To log in from outside of a script, one can also use `huggingface-cli login` which is a cli command that wraps login().

login() is a drop-in replacement method for notebook_login() as it wraps and extends its capabilities.

When the token is not passed, login() will automatically detect if the script runs in a notebook or not. However, this detection might not be accurate due to the variety of notebooks that exists nowadays. If that is the case, you can always force the UI by using notebook_login() or interpreter_login().

인터프리터_로그인

####
huggingface_hub.interpreter_login

< source >

( new_session: bool = True write_permission: bool = False )

Parameters

- new_session (`bool`, defaults to `True`) — If `True`, will request a token even if one is already saved on the machine.
- write_permission (`bool`) — Ignored and deprecated argument.

Displays a prompt to log in to the HF website and store the token.

This is equivalent to login() without passing a token when not run in a notebook. interpreter_login() is useful if you want to force the use of the terminal prompt instead of a notebook widget.

For more details, see login().

노트북_로그인

####
huggingface_hub.notebook_login

< source >

( new_session: bool = True write_permission: bool = False )

Parameters

- new_session (`bool`, defaults to `True`) — If `True`, will request a token even if one is already saved on the machine.
- write_permission (`bool`) — Ignored and deprecated argument.

Displays a widget to log in to the HF website and store the token.

This is equivalent to login() without passing a token when run in a notebook. notebook_login() is useful if you want to force the use of the notebook widget instead of a prompt in the terminal.

##
로그아웃

####
huggingface_hub.logout

< source >

( token_name: Optional = None )

Parameters

- token_name (`str`, optional) — Name of the access token to logout from. If `None`, will logout from all saved access tokens.

Raises

`ValueError`

- `ValueError` — If the access token name is not found.

Logout the machine from the Hub.

Token is deleted from the machine and removed from git credential.
