按照说明安装后,我跳转到他的示例:Inductive SVM(文档在同一页上)

Classifying test examples..100..200..300..400..500..600..done
Runtime (without IO) in cpu-seconds: 0.00
Accuracy on test set: 97.67% (586 correct, 14 incorrect, 600 total)
Precision/recall on test set: 96.43%/99.00%
有谁知道这是否应该是这样?如果没有,我该如何解决这个问题以使其正常工作?
仅供参考,我正在使用 OSX 10.9 和 python 2.7.5。
