我是R的新手,正在做xgboost,但它显示以下错误
preds< - predict(clf,testM)
xgb.DMatrix(newdata)中的错误: 矩阵中有NAN,但是,您没有设置missing = NAN
我还检查了我的xgb.DMatrix,我已经在错误中提到过:
dtrain< -xgb.DMatrix(data = trainMatrix,label = train_survived,missing = NaN)
执行时xgb.DMatrix没有错误
谁能告诉我问题出在哪里?
答案 0 :(得分:0)
The first predict line does not contain 'dtrain' at all. I can assume that another line of code was the reason of your error.
