Question

我在Windows 7上安装了32位Weka 3.6.10和32位Weka 3.7.10。当我进入Weka-3-6文件夹并输入

RunWeka

在DOS提示符下，Weka GUI Chooser出现了。但是，当我进入Weka-3-7文件夹并输入

时

RunWeka

没有任何反应 - 甚至没有任何错误消息。

与Weka 3.7.9,64位相同的问题。 Weka 3.7.9,64 bit，当我运行时

RunWeka console

我得到一个控制台提出以下内容。

Answer 1

我明白了。

我安装了较旧的（3.6）版本的Weka。因此，一个较旧的jar文件在我的类路径中。我在Windows 7上的解决方案是：
1 /开始
2 / R-单击计算机
3 /属性
4 /高级系统设置
5 /环境变量
6 /系统变量
7 / CLASSPATH：编辑
8 /删除任何与旧版Weka

有关的内容

在Windows 7上，runweka.bat似乎对Weka 3.7.10没有任何作用
