java - 为什么在 WEKA 中读取此 ARFF 文件时会出现过早的 EOF？

Question

这是我用于测试的简化版本，它会产生以下错误

@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
    at weka.core.converters.ArffLoader$ArffReader.errorMessage(ArffLoader.java:258) ~[weka-dev-3.7.6.jar:na]
    at weka.core.converters.ArffLoader$ArffReader.readHeader(ArffLoader.java:678) ~[weka-dev-3.7.6.jar:na]
    at weka.core.converters.ArffLoader$ArffReader.<init>(ArffLoader.java:139) ~[weka-dev-3.7.6.jar:na]

但是之前的版本似乎运行没有问题:

@RELATION documents

@ATTRIBUTE rnClass {r,n}
@ATTRIBUTE text String

@DATA
r,'blah blah blah...'
r,'\n\n\n\n\t\n\nblah blah blah\n\n...'
n,'\n\n   \n\n\n \nblah blah blah \n\n\nblah blah \n \n\n\n \'

我尝试使用您的输入创建一个 arff 文件，它对我有用。您的 arff 文件可能已损坏。您可以创建一个新的 arff 文件并尝试吗？
