5. 打开浏览器，输入网址
http://192.168.0.166:54323
会看到h2o的flow ui界面
6. 页面使用
6.1数据导入
选择左侧帮助部分的导入数据，importFiles
页面下方会显示出导入数据的界面，在search文本框上输入服务器上文件的路径，点击右侧的搜索按钮，页面会列出所有查到到的文件。然后点击Add all,没问题后点击import按钮
6.2 导入本地客户端数据
如果服务器上不存在要分析的文件，你可以选择上传自己的文件
6.3 解析导入的数据
如果你页面刷新了或者页面数据太乱了，你可以在getFrames里找到你刚才导入的数据集
找到我们刚才导入的数据集，点击parse按钮，
你可以自己输入列名，选择数据类型及其他修改，最后点击parse完成数据集的格式处理
点击上图中的view按钮，会显示下图，然后点击下图中的view data,会进行数据预览
数据预览查看：
parse完数据之后，你会发现数据集的扩展名已经由我们的.csv转为.hex，刷新一下页面，点击getFrames,
6.4 拆分数据集，
点击进入数据集，点击split按钮，
选择输入拆分比例，会拆分成多个数据集
6.5创建模型
点击顶菜单的'model -- k-meas'
选择算法，这里选择k-means,输入训练集training_frame和验证集validation_frame,或调整其他参数。
点击底部的create model按钮，会生成一个job,
点击view按钮，可查看模型的详细情况，如下图。
点击预测predict按钮,会显示下图，选择要预测的数据集，点击预测按钮即可查看结果。
