问题在r上安装h2o

我用安装包安装h2o。虽然我可以做h2o.init（），该h2o.autoML功能未发现：问题在r上安装h2o

could not find function "h2o.automl"

经过一番搜索我tar.gz.安装了“夜间前沿” version但安装后，即使h2o.init（）不再有效，并显示此错误：

Error: package or namespace load failed for ‘h2o’ in get(method, envir = home):

这是我试过甚至停止h2o.init（）从工作..谢谢 – santoku

的h2o.automl()功能已包括在过去的2个月夜间释放，所以应该在那里，如果你有正确安装了该软件包。我推荐在3.12“预览版”上发布夜间版本，因为3.12在AutoML中有一些错误。

每晚的释放（昨晚），可以在这里安装：

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

那些阅读本后，应访问this page获得链接到最新版本。

在R中安装后，启动H2O群集并验证版本。它应该是相同的，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
