Consider this example with Python 3.11, xgboost==2.0.3, and scikit-learn==1.4.1. import xgboost as xgb from sklearn.datasets import load_iris from sklearn.metrics import accuracy_score # Load dataset X, y = load_iris(return_X_y=True) # train multiclass classifier model = xgb.XGBCla...
I looked this up and I saw that the fit method can be passed a multitude of parameters, so I don't believe that the fact that I added early_stopping_rounds should cause problems. Any idea what could be the cause of this error? python jupyter xgboost Share Improve this question Follow ...
I am passing a custom evaluation metric function to XGBClassifier fit(), but the Python API discards callable (i.e., custom) functions. Why? It also seems to discard any string inputs. Regardless of what I pass in, the results are the same. I tried all objective functions as well, and...
