 def configure(self, argv=('',), **kwargs):
 """Configures TensorBoard behavior via flags. This method will populate the "flags" property with an argparse.Namespace representing flag values parsed from the provided argv list, overridden by explicit flags from remaining keyword arguments. Args: argv: Can be set to CLI args equivalent to sys.argv; the first arg is taken to be the name of the path being executed. kwargs: Additional arguments will override what was parsed from argv. They must be passed as Python data structures, e.g. `foo=1` rather than `foo="1"`. Returns: Either argv[:1] if argv was non-empty, or [''] otherwise, as a mechanism for absl.app.run() compatibility. Raises: ValueError: If flag values are invalid. """
