Serialize stochastic hashing function to be language-agnostic

I'm using the hashing function from here as part of a machine learning model. I need to use the trained model in C++, and thus I need the hashing function to be independent of the language (in this case Python/C++). How do I serialize a stochastic hashing function such that I can recreate the exact same hashing with same stochasticity in another language (C++)?
