我收到以下错误
c50 代码调用退出,值为 1
我正在根据 Kaggle 提供的泰坦尼克号数据进行此操作
# Importing datasets
train <- read.csv("train.csv", sep=",")
# this is the structure
str(train)
输出 :-
'data.frame': 891 obs. of 12 variables:
$ PassengerId: int 1 2 3 4 5 6 7 8 9 10 ...
$ Survived : int 0 1 1 1 0 0 0 0 1 1 ...
$ Pclass : int 3 1 3 1 3 3 1 3 3 2 ...

$ Embarked : Factor w/ 4 levels "","C","Q","S": 4 2 4 4 4 3 4 4 4 2 ...
然后我尝试使用 C5.0 dtree
# Trying with C5.0 decision tree
library(C50)
#C5.0 models require a factor outcome otherwise error
train$Survived <- factor(train$Survived)
new_model <- C5.0(train[-2],train$Survived)
所以运行上面的行给了我这个错误
c50 code called exit with value 1
我无法弄清楚出了什么问题?我在不同的数据集上使用了类似的代码,并且运行良好。关于如何调试代码的任何想法?
-谢谢
