我正在尝试使用 GUI 中的 Weka 的 CSVLoader 将 CSV 转换为 ARFF。在选项中，我将字符串的包围字符设置为"，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

这是第 1762-1764 行：

有任何想法吗？我似乎找不到错误。

EDIT---

当然，在我发布之后，我发现“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，或者其他角色不喜欢它吗？

如果将这些字符用作数据，通常会导致问题

, = " ' *+ -%

在 R 语言中使用此代码并更改文件它将 100% 解决您的问题

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

该错误是由第 1763 行中的撇号引起的。
