我正在尝试在我的 Dokerfile 中添加 DMLC 存储库，以便我可以安装 mxnet 包。我这样做如下：

RUN R -e "install.packages('drat', repos='https://cran.rstudio.com')"
RUN R -e "drat::addRepo('dmlc')"
RUN R -e "install.packages('mxnet', #repos='https://dmlc.github.io/drat',   dependencies=TRUE)"

这不起作用。令人惊讶的是，我注意到即使我添加了 dmlc 存储库，实际上当我打印出以下命令的输出时它并没有添加： 

RUN R -e "print(getOption('repos'))"

为了解决这个问题，我明确指定了 repos，如下所示：

#RUN R -e "install.packages('mxnet', #repos='https://dmlc.github.io/drat', dependencies=TRUE)"

这仍然没有奏效。它抛出一个错误说：

这是错误的截图

有什么帮助吗？我要做的就是在准备容器时在我的 Dockerfile 中安装 mxnet。

几点建议：

  1. 在将 R 命令与 Docker 一起使用之前，请确保它们在 Dockerfile 之外成功运行。对于您遇到的错误消息，该文件不存在，因此安装失败：http ://dmlc.ml/drat/src/contrib/mxnet_0.7.ta​​r.gz

  2. 我在 macOS X El Capitan 上尝试了以下步骤，但遇到了依赖包、rgexf 和 XML 的错误。但是，您能否检查以下步骤在您的环境中是否正常工作？

https://mxnet.incubator.apache.org/get_started/install.html

  cran <- getOption("repos")
  cran["dmlc"] <- "https://s3-us-west-2.amazonaws.com/apache-mxnet/R/CRAN/"
  options(repos = cran)
  install.packages("mxnet")

我遇到的错误：

Error in download.file(url, destfile, method, mode = "wb", ...) : 
  cannot download all files
In addition: Warning message:
In download.file(url, destfile, method, mode = "wb", ...) :

4: In install.packages("mxnet") :

然后，我尝试了：

cran <- getOption("repos")
cran["dmlc"] <- "https://apache-mxnet.s3-accelerate.dualstack.amazonaws.com/R/CRAN/"
options(repos = cran)
install.packages("mxnet")

Error in download.file(url, destfile, method, mode = "wb", ...) :

In addition: Warning message:

Warning in download.packages(pkgs, destdir = tmpd, available = available,  :
  download of package ‘mxnet’ failed

注意：这个错误不会停止安装，直到我遇到这个错误：

这些步骤可能适用于您的操作系统和环境。因此，请尝试它们并在此处发布您的发现。
