问题描述
我正在尝试增加java中的堆大小，因为weka会不断崩溃。我使用了建议的行：
I'm trying to increase the heap size in java for weka which keeps crashing. I used the suggested line:
> java -Xmx500m -classpath
但是我收到以下错误：
-classpath requires class path specification
我不确定这意味着什么。有什么建议吗？
I'm not sure what this means. Any suggestions?
推荐答案
我发现的实际问题是文件'RunWeka.ini' 在'\Program Files（x86）\Weka-3-6'中。我用记事本打开它，在文件中间有一行'maxheap = 512m'。
What I found was the actual issue was in the file 'RunWeka.ini' in '\Program Files (x86)\Weka-3-6'. I opened it with notepad and in the middle of the file there is a line 'maxheap = 512m'.
我将行更改为读取'maxheap = 2000m'，保存文件并重新加载weka并修复了我的问题问题。
I changed the line to read 'maxheap=2000m', saved the file and reloaded weka and this fixed my problems.
我不确定这是否是正确的方法，但它对我有用。
I'm not sure if this is the correct way to do it or not but it worked for me.
