Weka加载大数据量内存不足时不同平台的解决方法

ubuntu的解决方法

你只要在启动weka的时候，加上如下命令即可：

java -Xmx400M -jar weka.jar

From－－

I hit the JAVA OutOfMemory exception when I'm dealing with a largedataset. It seems that JAVA uses a default limit of 64Mb for itsmemory usage.  To increase the limit, you can try the JAVA -Xmx option, e.g.   java -Xmx400M -jar weka.jarThis increases the limit to 400 Mb (my system has 512Mb).  You shouldset your limit depending on the amount of memory you have available.See this link for more

如果你和我一样设置了脚本，就将weka脚本修改为

#! /bin/bash
java -Xmx400M -classpath $CLASSPATH:weka.jar:libsvm.jar weka.gui.GUIChooser

这样，就是400m了

 

windows方法

用文本编辑器打开RunWeka.ini找到:

# placeholders ("#bla#" in command gets replaced with content of key "bla")

# Note: "#wekajar#" gets replaced by the launcher class, since that jar gets
