Is there a way to save the object returned by Rbf?

savecancel

I am trying to use Rbf from scipy to interpolate scattered data. Is there a way to save the returned object (the function returned by Rbf command) rather than constructing the Rbf everytime I run the program. I saw this comment in rbf.py

attach anything left in kwargs to self for use by any user-callable function or to save on the object returned.

But I am not sure how to use it or whether it is actually what I am trying to do.
