H2o Rd警告：“文件链接丢失”

标签： r h2o automl

从Linux上的R下载H2o.ai时，我收到几个警告，提示文件丢失，例如：Rd warning: /tmp/RtmpdpaSKI/R.INSTALL1d3a6ccc7d9b/h2o/man/h2o.abs.Rd:32: missing file link 'abs'

我正在使用H2o的标准安装代码：install.packages("h2o", type="source", repos="http://h2o-release.s3.amazonaws.com/h2o/rel-xu/1/R")

这是带有警告的输出：     `h2o.abs html

我认为，使用automl Error: DistributedException from localhost/127.0.0.1:54321: 'Categorical value out of bounds

时，此问题会导致下游错误

2 个答案:

答案 0 :(得分：0)

这些是程序包中的错误，但不是很严重的错误。例如，您列出的第一个

Rd warning: /tmp/RtmpdpaSKI/R.INSTALL1d3a6ccc7d9b/h2o/man/h2o.ascharacter.Rd:16: missing file link ‘as.character’

之所以出现，是因为该帮助文件包含链接\link[base]{as.character}不存在。它应该是\link[base]{character}或\link[base:character]{as.character}，因为指向其他软件包的链接是指向帮助页面的名称，而不是主题别名。如果您使用?h2o.ascharacter寻求帮助，则可能会在帮助页面中找到指向as.character的链接无效。 （通常这样的链接有效，因为R动态帮助系统了解了作者的意思，但是某些安装使用带有内置.html文件的静态帮助系统，其中的链接无效。）

帮助系统中跨程序包链接的规则非常奇怪，看起来h2o的作者没有学习它们（或不在乎静态帮助）。

我不知道您对下游错误的猜测是否正确。

答案 1 :(得分：0)

您能否详细说明您所使用的系统和R的版本？我无法使用R 3.4.4在Ubuntu 16.04.5上重现此内容。我尝试完全按照您的方式安装，也尝试通过CRAN安装最新版本（均为3.22.0.1版）。

下游错误无关。如果您可以将正在运行的代码发布为带有可复制代码的独立问题，我们可以尝试对其进行梳理。
