Hi everyone,

I am working with Flower github example named /content/xgboost-comprehensive/

Is that possible to apply Differential Privacy to Flower XGboost strategy FedXgbBagging? When trying to wrap it within DifferentialPrivacyServerSideAdaptiveClipping, it does not run for me. If it is not possible, is there any other way to obtain private XGBoost in Flower?

Thanks in advance for any hint
