How to use the fvcore.common.file_io.PathManager.__get_path_handler function in fvcore

def exists(path: str, **kwargs: Any) -> bool:
        """
        Checks if there is a resource at the given URI.

        Args:
            path (str): A URI supported by this PathHandler

        Returns:
            bool: true if the path exists
        """
        return PathManager.__get_path_handler(path)._exists(  # type: ignore
            path, **kwargs
        )

Open a stream to a URI, similar to the built-in `open`.

        Args:
            path (str): A URI supported by this PathHandler
            mode (str): Specifies the mode in which the file is opened. It defaults
                to 'r'.
            buffering (int): An optional integer used to set the buffering policy.
                Pass 0 to switch buffering off and an integer >= 1 to indicate the
                size in bytes of a fixed-size chunk buffer. When no buffering
                argument is given, the default buffering policy depends on the
                underlying I/O implementation.

        Returns:
            file: a file-like object.
