在训练xgboost的时候,出现了这个错误:
File "E:\ana\lib\site-packages\sklearn\metrics\base.py", line 73, in _average_binary_score
raise ValueError("{0} format is not supported".format(y_type))
ValueError: continuous format is not supported
这个问题是自己手贱造成的,因为自己明明在做回归,结果是用的做分类的计分方式做的:
from sklearn.metrics import roc_auc_score
score = roc_auc_score(y_valid.values, check)
当然改回来就没事了
from sklearn.metrics import explained_variance_score
score = explained_variance_score(y_valid.values, check)
