I have a XGBoost.Booster which recieves a sparce matrix returned by FeatureHasher. There is no feature names. How to convert this type of model to CoreML and how to pass an array to that model?

Looks like model asks FeatureProvider for a feature only once. That means that features are hashed and threre is no sence in optimising the FeatureProvider.
