There is a error in XGBoostClassifier.py when I run amazon_main_xgboost.py. How can I solve it?

The error detail as below: Traceback (most recent call last): File "D:\Project\Tree\ensemble_amazon-master\amazon_main_xgboost.py", line 198, in preds=bagged_set(X_train,y_train,model, SEED , bagging, X_cv, update_seed=True)

I see.

Your version of xgboost is more recent than the example.

You need to do to https://github.com/kaz-Anova/ensemble_amazon/blob/master/XGBoostClassifier.py

and change default_direction=0 to default_direction ='learn'.

or I think you can just replace XGBoostClassifier.py with the one I have attached.

Let me know if it runs now.

@kaz-Anova Thanks you for answering me so promptly. Now the program is runing. I am waiting for the result.
