Question

我使用安装包来安装h2o。虽然我可以做h2o.init（），但找不到h2o.autoML函数：

could not find function "h2o.automl"

经过一番搜索，我在tar.gz中安装了“夜间流血'version。但安装后，甚至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):
 lazy-load database '/Library/Frameworks/R.framework/Versions/3.4/Resources/library/h2o/R/h2o.rdb' is corrupt
In addition: Warning messages:
1: In .registerS3method(fin[i, 1], fin[i, 2], fin[i, 3], fin[i, 4],  :

2: In get(method, envir = home) :

3: In get(method, envir = home) : internal error -3 in R_decompress1

Answer 1

h2o.automl()函数已包含在过去2个月的每晚版本中，因此如果您已正确安装该软件包，它应该在那里。我建议通过3.12＆＃34;预览版＆＃34;每晚发布一次。因为3.12在AutoML中有一些错误。

夜间发布（从昨晚开始）可以在这里安装：

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

稍后阅读此内容的人应访问this page以获取指向最新版本的链接。

在R中安装后，启动H2O群集并验证版本。它应该如下：

> 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:

Starting H2O JVM and connecting: .. Connection successful!

R is connected to the H2O cluster:

AutoML将包含在H2O 3.14.0.1的下一个稳定版本中，将在下一周或两周内发布。
