r - h2o.cbind只接受H2OFrame对象-R

我正在尝试使用R中的H2O与Logistic regres集成一个随机森林。但是，以下代码中出现错误消息：

> localH2O = h2o.init()
    Successfully connected to http://137.0.0.1:43329/

    R is connected to the H2O cluster:

    Error in h2o.cbind(predlist) :
      `h2o.cbind` accepts only of H2OFrame objects

显然，我的参数已正确给出，但是如您所见，消息：h2o.cbind accepts only of H2OFrame objects appears。错误的原因可能是什么？

最佳答案

看起来您可能正在使用h2o或h2oEnsemble软件包的较旧版本。 H2O数据帧的对象类以前称为H2OFrame，现在简称为Frame，而h2o.cbind正在寻找类型为H2OFrame的对象。

您可以通过将h2o和h2oEnsemble软件包更新为最新版本来解决此问题，如下所示：

# The following two commands remove any previously installed H2O packages for R.
if ("package:h2o" %in% search()) { detach("package:h2o", unload=TRUE) }
if ("h2o" %in% rownames(installed.packages())) {remove.packages("h2o") }

# Now we download, install and initialize the latest stable release of the *h2o* package for R.
install.packages("h2o", type="source", repos=(c("http://h2o-release.s3.amazonaws.com/h2o/rel-slater/5/R")))
library(h2o)

然后，如下更新h2oEnsemble：

library(devtools)
install_github("h2oai/h2o-3/h2o-r/ensemble/h2oEnsemble-package")

您随时可以在http://h2o.ai/download/上找到最新稳定的H2O版本（或最新版本）。
