Question

我想在我的Dokerfile中添加DMLC回購，以便我可以安裝mxnet軟件包。我這樣做如下：

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)" 

這是行不通的。出人意料的是，我發現，即使我加入DMLC回購，實際上它是不是當我打印出以下命令的輸出補充說：

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

要解決這個問題，我指定的回購明確如下：

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

仍然沒有工作。它拋出一個錯誤說：

任何幫助嗎？所有我想做的事情是在準備我的容器時在我的Dockerfile中安裝mxnet。

幾點建議：

1. 確保R命令Dockerfile外成功運行您泊塢窗使用它們之前。對於您遇到的錯誤消息，該文件不存在，因此安裝失敗：http://dmlc.ml/drat/src/contrib/mxnet_0.7.tar.gz

2. 我試着在MacOS X埃爾卡皮坦下列步驟和相關的軟件包，rgexf和XML面臨的一個錯誤。但是，您可以檢查下面的步驟是否在您的環境中正常工作？

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") 

錯誤由我遇到：

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

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

然後，我想：

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

In addition: Warning message:

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

注：此錯誤並不雖然停止安裝直到我碰到爲止■錯誤：

這是可能的，這些步驟可能您的操作系統和環境上工作。所以請嘗試他們並在此發佈您的發現。

後來，我在github上發現了這個問題。所以，你可以跟蹤這個問題有：
