    That isn't how you set parameters in xgboost. You would either want to pass your param grid into your training function, such as xgboost's train or sklearn's GridSearchCV, or you would want to use your XGBClassifier's set_params method. Another thing to note is that if you're using xgboost's wrapper to sklearn (ie: the XGBClassifier() or XGBRegressor() classes) then the paramater names used
