While trying to build an Xgboost model, I am getting this error. How to make this work?
# train xgboost num_round = 100 using XGBoost bst = xgboost(train_X, num_round, label=train_Y, eta=1, max_depth=2) LoadError: UndefVarError: xgboost not defined while loading In[33], in expression starting on line 4
