        scale_embedding (`bool`, *optional*, defaults to `False`):
            Scale embeddings by diving by sqrt(d_model).
        use_cache (`bool`, *optional*, defaults to `True`):
            Whether or not the model should return the last key/values attentions (not used by all models)
        forced_eos_token_id (`int`, *optional*, defaults to 2):
            The id of the token to force as the last generated token when `max_length` is reached. Usually set to
            `eos_token_id`.

    Example:

    ```python
    >>> from transformers import BlenderbotConfig, BlenderbotModel

    >>> # Initializing a Blenderbot facebook/blenderbot-3B style configuration
    >>> configuration = BlenderbotConfig()

    >>> # Initializing a model (with random weights) from the facebook/blenderbot-3B style configuration
    >>> model = BlenderbotModel(configuration)

    >>> # Accessing the model configuration
    >>> configuration = model.config
