A dict specifying how to populate the assets.extra directory
within the exported SavedModel. Each key should give the destination
path (including the filename) relative to the assets.extra directory.
The corresponding value gives the full path of the source file to be

renaming it is specified as
whether to write the SavedModel proto in text format.
Number of exports to keep. Older exports will be
garbage-collected. Defaults to 5. Set to None to disable garbage
Boolean. If True, default attrs in the
GraphDef will be stripped on write. This is recommended for better
forward compatibility of the resulting SavedModel.
An ExportStrategy that can be passed to the Experiment constructor.
