Java 将arff文件打开到weka时出错

无论何时在weka中打开此文件，都会不断收到错误“未识别为”Arff数据文件“文件。原因：应为数字，读取标记[M]，第16行。然而，每当我试图纠正错误时，就会弹出另一个错误。这是一个新手，所以谁都知道我在哪里犯了错误。谢谢你的帮助

数据中有10个属性行，但只有9个属性

此外，在您的数据中，代码是M、F、I，但您在属性语句中指出它们是男性、女性、婴儿

我猜您认为您只是将类分配给sex，但是Weka中的class变量自动成为最后一个变量。我已经在下面为您重新安排了这个，并验证了它将正确加载

@relation 'abalone'

@attribute length numeric
@attribute diameter numeric
@attribute height numeric
@attribute wholeWeight numeric
@attribute shuckedWeight numeric
@attribute visceraWeight numeric
@attribute shellWeight numeric
@attribute rings numeric
