 def get_temp_export_dir(timestamped_export_dir):

This relies on the fact that TensorFlow Serving ignores subdirectories of the base directory that can't be parsed as integers. Args: timestamped_export_dir: the name of the eventual export directory, e.g. /foo/bar/<timestamp> Returns: A sister directory prefixed with 'temp-', e.g. /foo/bar/temp-<timestamp>. """
