scala on Windows

[evanthomas]

I want to develop on windows with scala. The windows installation instructions (https://mxnet.incubator.apache.org/get_started/windows_setup.html) refer to binaries for Windows that don't seem to exist. The instructions for building yourself require Visual Studio 2013 which is no longer available. I've found the prebuilt binaries in the fork but they are only for python and don't have mxnet-scala.dll.

Is scala+mxnet+windows possible?

I'm facing the same issues. Since no answer here, I assume that there is no support for scala + mxnet + windows. right?

I'm facing the same issues.

We are building MXNet in our CI on Windows, so there is definitely some support.
@nswamy might be of help here

Need this fixed, too. I would like to use it from java on windows.

If found a link of microsoft to older releases; maybe it helps:

1. Steps for building on windows have been revised and merged. We need to use VS 2015, not VS 2013.
   ( PR - Revising steps for building MXNet on Windows platform  #8619 for Windows builds)
   Please check this-
   https://mxnet.incubator.apache.org/install/windows_setup.html
2. Scala specific steps need to be updated.

Scala support on Windows is not yet available for MXNet, unfortunately.
@nswamy and @lanking520 have been doing some awesome work to improve Scala MXNet API. Hoping they will be able to work on Scala and Windows as well - stay tuned!

Hi hagay, could you elaborate on the issue you are encountering with windows? Considering Scala is based on the JVM and we're successfully running the Backend of MXNet on our Windows CI, there might be something we could do quickly :)

[nswamy]

Please free to attempt to build a Windows version. from what I can see It needs windows based native code(JNI)

Aaaah I see, JNI is the problem here. Got it, thank you! Agree, that might take a bit of time :/

@evanthomas I tagged you on an another issue we'll be tracking and closing this.
