问题描述

displayed message:
Not enough memory. Please load a smaller dataset or use larger heap size.
- initial JVM size:   15.5MB
- total memory used:  989.9MB
- max. memory avail.: 989.9MB

Note:
The Java heap size can be specified with the -Xmx option.
E.g., to use 128MB as heap size, the command line looks like this:
   java -Xmx128m -classpath ...
This does NOT work in the SimpleCLI, the java command refers
to the one with which Weka is started.

方法一

C：\software\java -Xmx1024m -jar weka.jar

方法二：

RunWeka.ini

maxheap=1024m

再学习：

Your HEAP size limitation is not about your Operating System only. But your heap size may be limited by following factors.32 bit and 64 bit OS
Other programs running 
Your maximum physical RAM available in your machine
