ultralytics.hub.auth.Auth

Gère les processus d'authentification, notamment la gestion des clés API, l'authentification basée sur les cookies et la génération d'en-têtes.

La classe prend en charge différentes méthodes d'authentification : 1. Directement à l'aide d'une clé API. 2. En s'authentifiant à l'aide des cookies du navigateur (spécifiquement dans Google Colab). 3. En invitant l'utilisateur à saisir une clé API.

Attributs :

Nom Type Description
id_token str or bool

Jeton utilisé pour la vérification de l'identité, initialisé à False.

api_key str or bool

Clé API pour l'authentification, initialisée à False.

model_key bool

Emplacement pour la clé du modèle, initialisé à False.
