如何在Mac上将LibSVM类添加到WEKA类路径 [英] How to add LibSVM class to WEKA classpath on a Mac

问题描述

我正在运行Max OS X 10.7 Lion，我想从命令行使用WEKA和LibSVM。我收到此错误：

 评估分类器的问题：libsvm类不在CLASSPATH中！ 
  

我找到了LibSVM库

转到Mac上的/ Applications文件夹（安装Weka应用程序的文件夹）

右键单击Weka>选择显示包内容

将libsvm.jar复制到/Applications/Weka.app/Contents/Resources/Java

在您喜欢的文本编辑器中打开/Applications/Weka.app/Contents/Info.plist

将< string> $ JAVAROOT / weka.jar< / string> 更改为< string> $ JAVAROOT / weka.jar：$ JAVAROOT / libsvm.jar< / string> （你也可以在这里调整堆大小）

保存并启动weka

I am running Max OS X 10.7 Lion and I want to use WEKA with LibSVM from command line. I get this error:

Problem evaluating classifier: libsvm classes not in CLASSPATH!

I found the LibSVM library here. I need to add it to my Java classpath so that WEKA can find it. The download contains several files, shown below. I don't know how to add them to my classpath for Java.

I am attempting to use the LibSVM classifier in WEKA because it is preferable for me over SMO. I am also unsure if this means the Java classpath or if it is specific to WEKA. I also don't know where to get these classes from. Any help is appreciated.

解决方案

Here is another extremely easy way to add LibSVM support to WEKA on OS X (no command line needed):

1. Download LibSVM from here
2. Go to /Applications folder on your Mac (the folder where the Weka app is installed)
3. Right click on Weka > Chose "Show Package Contents"
4. Copy libsvm.jar to /Applications/Weka.app/Contents/Resources/Java
5. open /Applications/Weka.app/Contents/Info.plist in your favorite text editor
6. change <string>$JAVAROOT/weka.jar</string> to <string>$JAVAROOT/weka.jar:$JAVAROOT/libsvm.jar</string> (you can also adjust the heap size here)
7. Save and start weka
