> I saved a CrossValidatorModel with a decision tree and a random forest. I use Paramgrid
to test "gini" and "entropy" impurity. CrossValidatorModel are not able to load the saved
model, when impurity are written not in lowercase. I obtain an error from Spark "impurity
Gini (Entropy) not recognized.
