在 R 中使用 as.H2o 时出错

Question

使用 as.h2o 时出现错误。有人有想法吗？

library(pacman)
p_load(h2o)
data(iris)
localH2O = h2o.init(ip = 'XXX.XX.XX.XXX', port = XXXXX, strict_version_check = FALSE)
train_hex <-  as.h2o(iris, destination_frame = "train_hex")
|=====================================================| 100%
Error in class(obj) <- "rs.scalar" : attempt to set an attribute on NULL

如果我尝试不分配它，这就是错误。

as.h2o(iris,  destination_frame = "train_hex")

这里有一些关于我的环境和计算情况的附加信息。

这可能是由于运行不兼容的版本 and/or 运行集群上的开发版本（版本号末尾的“.9999”）。

我建议您卸载并安装最新的 R 客户端，遵循 these instructions。尝试最新的稳定构建，如果运气不好，请尝试每晚构建。如果还是不行，请考虑将集群升级到最新的稳定版或最新的 nightly。
