class LukeConfig(PreTrainedConfig):
    r"""
    entity_vocab_size (`int`, *optional*, defaults to 500000):
        Entity vocabulary size of the LUKE model. Defines the number of different entities that can be represented
        by the `entity_ids` passed when calling [`LukeModel`].
    entity_emb_size (`int`, *optional*, defaults to 256):
        The number of dimensions of the entity embedding.
    use_entity_aware_attention (`bool`, *optional*, defaults to `True`):
        Whether or not the model should use the entity-aware self-attention mechanism proposed in [LUKE: Deep
        Contextualized Entity Representations with Entity-aware Self-attention (Yamada et
        al.)](https://huggingface.co/papers/2010.01057).

    Examples:

    ```python
    >>> from transformers import LukeConfig, LukeModel

    >>> # Initializing a LUKE configuration
    >>> configuration = LukeConfig()

    >>> # Initializing a model from the configuration
    >>> model = LukeModel(configuration)

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