    dim_bbox (`int`, *optional*, defaults to 8):
        The dimension of the bounding box coordinates. (x0, y1, x1, y0, x1, y1, x0, y1)
    bbox_scale (`float`, *optional*, defaults to 100.0):
        The scale factor of the bounding box coordinates.
    n_relations (`int`, *optional*, defaults to 1):
        The number of relations for SpadeEE(entity extraction), SpadeEL(entity linking) head.

    Examples:

    ```python
    >>> from transformers import BrosConfig, BrosModel

    >>> # Initializing a BROS jinho8345/bros-base-uncased style configuration
    >>> configuration = BrosConfig()

    >>> # Initializing a model from the jinho8345/bros-base-uncased style configuration
    >>> model = BrosModel(configuration)

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