How to install the R package for mxnet?

Question

I used to work with the mxnet package in R. I have an old installation and I can use it in R 3.4x but now I want to switch to the newest R version (R 3.5 locally) and I would love to use it on rstudio.cloud. The package was on CRAN (wasn't it?) Now I try to follow the instructions from the packgage page:

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

and I get the following result:

installing the source package ‘mxnet’

trying URL 'https://apache-mxnet.s3-accelerate.dualstack.amazonaws.com/R/CRAN/src/contrib/mxnet_0.10.1.tar.gz' Warning in install.packages : cannot open URL 'https://apache-mxnet.s3-accelerate.dualstack.amazonaws.com/R/CRAN/src/contrib/mxnet_0.10.1.tar.gz': HTTP status was '404 Not Found' Error in download.file(url, destfile, method, mode = "wb", ...) : cannot open URL 'https://apache-mxnet.s3-accelerate.dualstack.amazonaws.com/R/CRAN/src/contrib/mxnet_0.10.1.tar.gz' Warning in install.packages : download of package ‘mxnet’ failed

Is there a way to install mxnet for R from the R command line (so I can try it in the cloud as well)? or I have to switch to keras entirely ....:)

Any help is appreciated.

my sessioninfo is:

Answer 1

I answer my own question as it was really hard for me to find the answer and others could benefit.

The following line installs the CPU version:

install.packages("https://github.com/jeremiedb/mxnet_winbin/raw/master/mxnet.zip", repos = NULL)

I found it in the Q & A forum.
