尝试阅读时：

import arff
arff.loads('result.arff')

我得到以下错误：

arff.BadLayout:第1行的arff文件布局无效

---

我找不到问题。Weka打开文件，但不使用python包。。。有什么想法吗？提前谢谢

查看上的ARFF模块文档，load（）将一个文件对象作为输入。看起来您在result.arff文件中有上述数据，因此您应该将其加载为：

fp = open('result.arff')
testdata = arff.load(fp)

这将解决与arff.BadLayout有关的上述错误。

，而不是文件名：

将包含ARFF文档的字符串实例转换为Python对象

可以对文件对象使用

load

，也可以将文件读入字符串并以这种方式传递
