Zy)r   aP  Create a Detectron2-based Layout Detection Model

    Args:
        config_path (:obj:`str`):
            The path to the configuration file.
        model_path (:obj:`str`, None):
            The path to the saved weights of the model.
            If set, overwrite the weights in the configuration file.
            Defaults to `None`.
        label_map (:obj:`dict`, optional):
            The map from the model prediction (ids) to real
            word labels (strings). If the config is from one of the supported
            datasets, Layout Parser will automatically initialize the label_map.
            Defaults to `None`.
        device(:obj:`str`, optional):
            Whether to use cuda or cpu devices. If not set, LayoutParser will
            automatically determine the device to initialize the models on.
        extra_config (:obj:`list`, optional):
            Extra configuration passed to the Detectron2 model
            configuration. The argument will be used in the `merge_from_list
            <https://detectron2.readthedocs.io/modules/config.html
            #detectron2.config.CfgNode.merge_from_list>`_ function.
            Defaults to `[]`.

    Examples::
        >>> import layoutparser as lp
        >>> model = lp.Detectron2LayoutModel('lp://HJDataset/faster_rcnn_R_50_FPN_3x/config')
        >>> model.detect(image)
