Incubator-mxnet: Cannot install MXNet R (cannot open URL)

[Kurokokoro]

Hi, recently i tried installing MXNet with RStudio on Windows 7. After the command:
install.packages("mxnet")
I got error:
Warning in install.packages : package ‘mxnet’ is not available (for R version 3.5.1)

After:
cran <- getOption("repos") cran["dmlc"] <- "https://apache-mxnet.s3-accelerate.dualstack.amazonaws.com/R/CRAN/" options(repos = cran) install.packages("mxnet")
I got:
trying URL 'https://apache-mxnet.s3-accelerate.dualstack.amazonaws.com/R/CRAN/src/contrib/mxnet_1.3.0.tar.gz' Warning in install.packages : cannot open URL 'https://apache-mxnet.s3-accelerate.dualstack.amazonaws.com/R/CRAN/src/contrib/mxnet_1.3.0.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_1.3.0.tar.gz' Warning in install.packages : download of package ‘mxnet’ failed

And finally, after (found somewhere here when seaching for fix):
install.packages("https://github.com/jeremiedb/mxnet_winbin/raw/master/mxnet.zip", repos = NULL)
It installed but when trying to load library:
Error: pakiet ‘mxnet’ nie jest zainstalowany dla 'arch=i386'

I know that Windows 7 is not fully supported but I hope it's not that case.
So the file on server is missing or something?
I would be very grateful if someone could help me
Thanks

@Kurokokoro Thanks for raising the issue. Let me ask the in-house R Gurus to try to resolve this for you.
@anirudhacharya @jeremiedb @ankkhedia @hetong007 Can you guys have a look at this ?

@mxnet-label-bot Add [R]

[ankkhedia]

@Kurokokoro Do you have OpenBlas already installed in your system?

I am not sure if it is a Windows 7 issue but the installation works fine for Windows10. Alternatively you can try building from source using the instructions mentioned in http://mxnet.incubator.apache.org/install/windows_setup.html#install-mxnet-package-for-r

[jeremiedb]

If still having issue, you may try this version compatible with R >= 3.5.0:
install.packages("https://s3.ca-central-1.amazonaws.com/jeremiedb/share/mxnet/CPU/mxnet.zip", repos = NULL)

I'd guess the issue encountered was related to the installation for R <= 3.4 rather than Windows 7. Let me know otherwise.

@Kurokokoro Do you have OpenBlas already installed in your system?

I tried but installation had an error, I have precompiled binaries but no idea on how to implement it with RStudio.
In Windows 10 Mxnet worked in RStudio without installing OpenBlas as I remember

If still having issue, you may try this version compatible with R >= 3.5.0:
install.packages("https://s3.ca-central-1.amazonaws.com/jeremiedb/share/mxnet/CPU/mxnet.zip", repos = NULL)

Still gives error:
trying URL 'https://s3.ca-central-1.amazonaws.com/jeremiedb/share/mxnet/CPU/mxnet.zip' Warning in install.packages : cannot open URL 'https://s3.ca-central-1.amazonaws.com/jeremiedb/share/mxnet/CPU/mxnet.zip': HTTP status was '403 Forbidden' Error in download.file(p, destfile, method, mode = "wb", ...) : cannot open URL 'https://s3.ca-central-1.amazonaws.com/jeremiedb/share/mxnet/CPU/mxnet.zip'

Thanks for your help so far :D

@Kurokokoro Could you give another shot, I think I had failed to change the status to public.

[Kurokokoro]

It downloads:
trying URL 'https://s3.ca-central-1.amazonaws.com/jeremiedb/share/mxnet/CPU/mxnet.zip' Content type 'application/zip' length 30382408 bytes (29.0 MB) downloaded 29.0 MB

But unfortunately gives the same error when trying to load library:
Error: package ‘mxnet’ is not installed for 'arch = i386'

[jeremiedb]

Oh I missed the 32 bits part. 32 bits isn't supported. Can't you use R 64 bits on Windows 7?

[Kurokokoro]

I missed that as well, I switched to 64 bit version and it works now.
Thank you very much :)

@Kurokokoro Great to know its working for you. Should we close this issue in that case?

[Kurokokoro]

Yes please, thanks for help again
