Question

我在Windows机器上尝试基本的systemML教程。但是，由于指令适用于OS X和Linux，因此我在实现

时遇到了一些问题

例如，在处理我已下载的Habeman数据集并将其作为haberman.data保存在文件夹数据中时所述here我收到此错误

非常感谢任何帮助

这可能只是data / haberman.data.mtd文件末尾缺少的换行符（因为它在解析此json文件时当前失败）。

如果这没有帮助，这里有一个解决方法：由于SystemML不一定需要ctd输入数据的mtd文件，你也可以删除mtd文件并在Univar的read语句中放入format =“csv” Stats.dml。

在Windows系统上运行systemml代码
