5. 打開瀏覽器，輸入網址
http://192.168.0.166:54323
會看到h2o的flow ui界面
6. 頁面使用
6.1數據導入
選擇左側幫助部分的導入數據，importFiles
頁面下方會顯示出導入數據的界面，在search文本框上輸入服務器上文件的路徑，點擊右側的搜索按鈕，頁面會列出所有查到到的文件。然后點擊Add all,沒問題后點擊import按鈕

如果服務器上不存在要分析的文件，你可以選擇上傳自己的文件
6.3 解析導入的數據
如果你頁面刷新了或者頁面數據太亂了，你可以在getFrames里找到你剛才導入的數據集
找到我們剛才導入的數據集，點擊parse按鈕，
你可以自己輸入列名，選擇數據類型及其他修改，最后點擊parse完成數據集的格式處理
點擊上圖中的view按鈕，會顯示下圖，然后點擊下圖中的view data,會進行數據預覽
數據預覽查看：
parse完數據之后，你會發現數據集的擴展名已經由我們的.csv轉為.hex，刷新一下頁面，點擊getFrames,
6.4 拆分數據集，
點擊進入數據集，點擊split按鈕，
選擇輸入拆分比例，會拆分成多個數據集
6.5創建模型
點擊頂菜單的'model -- k-meas'
選擇算法，這里選擇k-means,輸入訓練集training_frame和驗證集validation_frame,或調整其他參數。
點擊底部的create model按鈕，會生成一個job,
點擊view按鈕，可查看模型的詳細情況，如下圖。
點擊預測predict按鈕,會顯示下圖，選擇要預測的數據集，點擊預測按鈕即可查看結果。
