Java 为什么在WEKA中读取此ARFF文件会导致过早的EOF？

下面是我用于测试的简化版本，它会产生下面的错误

@RELATION documents

@ATTRIBUTE rnClass {r,n}
@ATTRIBUTE CONTAINS_EMAIL numeric
@ATTRIBUTE CONTAINS_PHONE numeric

@DATA
n,0.0,0.0
n,0.0,0.0
r,0.0,0.0
r,0.0,0.0
n,0.0,0.0
r,0.0,0.0
r,0.0,0.0


Caused by: java.io.IOException: premature end of file, read Token[EOF], line 1

我试着用你的输入创建一个arff文件，它对我有用。可能是您的arff文件已损坏。能否创建一个新的arff文件并重试

我在尝试使用记事本++生成一些文件进行数据挖掘实验时遇到了这个问题。我怀疑这可能是一个编码问题，以某种方式破坏了文件，使WEKA停止工作。您应该尝试更改文件编码配置：如果您使用UTF-8编码创建文件，则应更改为ANSI或其他编码。它成功了。

只是为了确定，你能试试我的arff文件吗？你可以从下面的链接下载。
