MXNet軟件包安裝在R

Question

我試圖安裝時遇到了很多麻煩MXNet package in R 我使用R的3.4.0版本，我在windows 10 CPU intel i3,64位x64處理器上。

我得到提示：

install.packages("mxnet") 
Warning in install.packages : 
    cannot open URL 'http://www.stats.ox.ac.uk/pub/RWin/src/contrib/PACKAGES.rds': HTTP status was '404 Not Found' 
Installing package into ‘C:/Users/los40/OneDrive/Documentos/R/win-library/3.4’ 
(as ‘lib’ is unspecified) 
Warning in install.packages : 
    package ‘mxnet’ is not available (for R version 3.4.0) 
Warning in install.packages : 
    cannot open URL 'http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.4/PACKAGES.rds': HTTP status was '404 Not Found' 

我嘗試下載這裏提供的.rar文件。我解一個，並得到它說：「R包」，試圖通過使用安裝的文件夾：

> install.packages('R.package.rar', lib='D:/mxnet',repos = NULL) 
Error in install.packages : type == "both" cannot be used with 'repos = NULL' 
> install.packages('R.package.rar', lib='D:/mxnet') 
Warning in install.packages : 
    package ‘R.package.rar’ is not available (for R version 3.4.0) 

在http://mxnet.io/get_started/windows_setup.html發現該指南是沒有意義的我，因爲我無法找到了安裝步驟所需的文件在Windows上預生成包稱爲setupenv.cmd
