[SciPy-user] Serializing LSQUnivariateSpline?

[David Warde-Farley]

I have a bit of a dilemma: I like the LSQUnivariateSpline wrapper, but  
I need to serialize the fitted splines, and be able to reconstruct  
them.  (I'm using pytables as a backend, by the way).

(t,c,k) pairs are slightly easier to work with in this respect but  
less descriptive and less elegant when actually using them.

The pickled description of even a simple one of these objects leans  
towards three kiliobytes, and I'm going to be working with a lot of  
them. I'm thinking of going with an HDF5 table of all the contents of  
_data as I think I  can get an okay read of what sizes and types are  
required, but what about deserializing? Is there some obvious way I'm  
missing?

Any ideas are appreciated,

David
