    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`.
        enforce_cpu(:obj:`bool`, optional):
            When set to `True`, it will enforce using cpu even if it is on a CUDA
            available device.
        extra_config (:obj:`dict`, optional):
            Extra configuration passed to the EfficientDet model
            configuration. Currently supported arguments:
                num_classes: specifying the number of classes for the models
                output_confidence_threshold: minmum object prediction confidence to retain

    Examples::
        >>> import layoutparser as lp
        >>> model = lp.EfficientDetLayoutModel("lp://PubLayNet/tf_efficientdet_d0/config")
        >>> model.detect(image)
