I'm tryring to save a pyoperon model using pickle:

from pyoperon.sklearn import SymbolicRegressor
reg = SymbolicRegressor()
reg.fit(X_train, y_train)

filename = 'operon_model.sav'
pickle.Dump(reg, open(filename, 'wb'))

but I get the following error:

TypeError: cannot pickle 'pyoperon.pyoperon.Variable' object

Can help me with this issue? Thanks
