        Run inference on an image.

        Args:
            image_path (str): path to the image you'd like to perform prediction on
            hosted (bool): whether the image you're providing is hosted on Roboflow

        Returns:
            PredictionGroup Object

        Example:
            >>> import roboflow

            >>> rf = roboflow.Roboflow(api_key="")

            >>> project = rf.workspace().project("PROJECT_ID")
