問題在r上安裝h2o

我用安裝包安裝h2o。雖然我可以做h2o.init（），該h2o.autoML功能未發現：問題在r上安裝h2o

could not find function "h2o.automl"

經過一番搜索我tar.gz.安裝了「夜間前沿」 version但安裝後，即使h2o.init（）不再有效，並顯示此錯誤：

Error: package or namespace load failed for ‘h2o’ in get(method, envir = home): 
lazy-load database '/Library/Frameworks/R.framework/Versions/3.4/Resources/library/h2o/R/h2o.rdb' is corrupt 
In addition: Warning messages:

這是一個解決您的問題：https://groups.google.com/forum/#!topic/h2ostream/CQ96Lwlv4PY – PoGibas

這是我試過甚至停止h2o.init（）從工作..謝謝 – santoku

的h2o.automl()功能已包括在過去的2個月夜間釋放，所以應該在那裏，如果你有正確安裝了該軟件包。我推薦在3.12「預覽版」上發佈夜間版本，因爲3.12在AutoML中有一些錯誤。

每晚的釋放（昨晚），可以在這裏安裝：

install.packages("h2o", type="source", repos="https://h2o-release.s3.amazonaws.com/h2o/master/3978/R")

那些閱讀本後，應訪問this page獲得鏈接到最新版本。

在R中安裝後，啓動H2O羣集並驗證版本。它應該是相同的，如下：

> h2o.init() 
Reading in config file: ./../../.h2oconfig 

H2O is not running yet, starting it now... 

Note: In case of errors look at the following log files: 
    /var/folders/2j/jg4sl53d5q53tc2_nzm9fz5h0000gn/T//RtmpV47QKn/h2o_me_started_from_r.out
