Question

我正在尝试使用来自GUI的Weka的CSVLoader将CSV转换为ARFF。在选项中，我将字符串的机箱字符设置为"，尽管我的文件中没有引号。我收到以下错误：

weka.core.converters.CSVLoaderfailed to lead <my file>
Reason:
wrong number of values. Read 2, expected 23, read Token[EOL], line 1763

以下是第1762-1764行：

有什么想法吗？我似乎无法找到错误。

EDIT---

当然，我发布后发现“错误”CSVLoader不喜欢％字符。所以，我改变了我的问题：有谁知道这是为什么或其他角色不喜欢它？

Answer 1

如果用作数据

，这些字符通常会导致问题

，=“'* + - ％

Answer 2

在R语言中使用此代码并更改文件，它将解决您的问题100％

mydata=read.csv("train.csv",header=TRUE)
library("foreign")
write.arff(x =mydata ,file= "train.arff")

Answer 3

错误是由第1763行的撇号引起的。

Weka CSVLoader错误的值数。阅读2，预计23
