我尝试在带有 R 3.5.0 的 RHEL 6.7 服务器上使用 H2O。这是我在使用 library(h2o) 加载包后发出 h2o.init() 命令时发生的情况:
H2O is not running yet, starting it now...
Note: In case of errors look at the following log files:

任何帮助使其发挥作用的帮助将不胜感激!我过去曾使用过 H2O，并且是 H2O 的忠实粉丝。
谢谢!
最佳答案
实际上 H2O 确实从这里开始。指示在网络浏览器中打开 Flow 的消息就是标志。
但是 R 客户端无法连接到 H2O，因此决定放弃。
底部的消息有 504。
这是 HTTP 状态 504。这可能是 RHEL 防火墙阻止了端口 54321。您需要在防火墙中打开端口 54321。
关于r - Can't start H2O in R : Error in h2o. init() H2O 启动失败，停止执行，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/54380323/
