R包h2o 3.13.0.356版本
我从h2o_3.13.0.356版本的Docker镜像运行h2o。 我想从R命令，但我有一个不同的版本。 我可以连接群集，但许多function不起作用。 例如h2o.importFile抛出错误：

有没有可能在Docker镜像的版本中安装R h2o软件包？
问题是，当我们在使用importFile函数来支持encryption数据的企业function上工作时，您正在使用最新版本的代码（以及较旧的版本），因此您可能遇到了这个问题。 我们现在已经完成了开发这个function。 所以你只需要将H2O更新到你的后端和R API的最新版本。
最新的STABLE版本3.14.0.3可以从这里下载，请确保你安装了最新的H2O R软件包：
https://h2o-release.s3.amazonaws.com/h2o/rel-weierstrass/3/index.html
最近的出血也没有这个问题，所以你可以尝试一下。
