1、xgboost.core.XGBoostError: b"Invalid Parameter format for max_depth expect int but value

params = {‘n_estimators’ : 150, ‘min_child_weight’ : 3, ‘max_depth’:
6} xgb_model = xgb.XGBClassifier(params) xgb_model.fit(train_x,
train_y) xgb_result = xgb_model.predict(test_x)

解决方案
xgb_model = xgb.XGBClassifier(**params)
