How can I install the newest mxnet R package?

[markusdumke]

When I run

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

this will install mxnet 0.10.1. How can I install mxnet 0.12.1?

This is the sessionInfo output:

Previously I have downloaded prebuildbase_win10_x64_vc14_v2.7z and 20171114_mxnet_x64_vc14_cpu.7z, unzipped this and put both into a folder MXNet. Then I double clicked setupenv.cmd.

I also had issues compiling latest version for Windows, but up to version 0.10 the following receipe using the prebuild files worked fine, so maybe you'll have it work: https://github.com/jeremiedb/mxnet_winbin
To work on the latest latest version, I've opted for either a Ubuntu VM or a docker image.

@thirdwing
Windows pre-built package seems in need for some tuning for installing R.
Issues arise from im2rec.cc that include header from opencv2/opencv.hpp. That can be solved by adding the opencv2 source files from a seperate OpenCV installation.

Another issue is with C++11, which is not supported by default. A fix is to add SystemRequirements: C++11 to the in the DESCRIPTION file.

After these fix, the package can compile up to symbol.o, but then crashes with the following message:

im2rec.o:im2rec.cc:(.text+0x5856): undefined reference to `cv::String::deallocate()'
im2rec.o:im2rec.cc:(.text$_ZN2cv3MatD1Ev[_ZN2cv3MatD1Ev]+0x91): undefined reference to `cv::Mat::deallocate()'
im2rec.o:im2rec.cc:(.text$_ZN2cv3MatD1Ev[_ZN2cv3MatD1Ev]+0x75): undefined reference to `cv::fastFree(void*)'
collect2.exe: error: ld returned 1 exit status

That seems tied to #7428 #8240 and #7273

Hi @markusdumke The binaries on the official repo(for Windows) has been updated. Could you please follow the instructions there to install R and verify if it is working for you. I am closing this issue. Please feel free to re-open in case it is closed in error.

@sandeep-krishnamurthy Could you please close this issue
