Any way to serialize/pickle a vptree?

[Bewinxed]

I'm using VP-Tree in a reverse image search engine implementation, I have a 64-bit integers that I build a vp-tree out of.

I don't want to initiate this vp-tree every time i query for it, i want to store the vp tree somewhere and retrieve it.

However, when I try to pickle this object using pickle.dumps it gives me an error.

Is it possible?

Thanks!
