R package h2o 3.13.0.356版本

Question

我正在从一个h2o_3.13.0.356版本的docker镜像运行h2o。我想从R命令它，但我有一个不同的版本。我可以与集群连接，但很多功能都不起作用。例如，h2o.importFile抛出错误：

ERROR: Unexpected HTTP Status code: 412 Precondition Failed (url = http://localhost:54321/3/Parse)

Error in .h2o.doSafeREST(h2oRestApiVersion = h2oRestApiVersion, urlSuffix = page,  : 


ERROR MESSAGE:

Unknown parameter: decrypt_tool

是否有可能将R h2o包安装为与docker镜像相同的版本？

Answer 1

问题是，当我们使用企业函数来支持使用importFile函数加密的数据时，您使用的是最先进的代码版本(以及更老的版本)，所以您可能遇到了这个问题。我们现在已经完成了这个功能的开发。所以你只需要在你的后台将H2O更新到最新的发布版本，同时也更新R即可。

最新的稳定版本3.14.0.3可以从这里下载，请确保您也安装了最新的H2O R包：

https://h2o-release.s3.amazonaws.com/h2o/rel-weierstrass/3/index.html

最新的出血也没有这个问题，所以你也可以尝试一下。

http://h2o-release.s3.amazonaws.com/h2o/master/4052/index.html

H2O 3.14.0.3文件导入示例

> h2o.init()
