MXNET on Windows?

[profK]

The front page says Releases has a pre-built package for windows but all I see there are src packages. Is there still a pre-built package for Windows?

If not, are there proven instructions for building on Windows with VS2022? I have gotten CMAKE to run without errors but building with VS errors out with
an inability to find mxnet-cpp/op.h

Using msbuild I get a long list of link errors:
msbuild -property:USE_CPP_PACKAGE=1 /m:1 ALL_BUILD.vcxproj

I’ve been workign on this for the better part of a week with no success 😦

Link errors below:

Update. I figured out that the script was looking for python3.exe whereas my python 3 is just called python.exe so I copied it to python3.exe. Rebuilding, fingers crossed.

So, now I am gtting this...

Update: looks like its one of the dependencies because it is there...

OpWrapperGenerator.py needs load libmxnet.dll. It will need all the dependencies either under the same folder or under the environment path.

I manually build 1.9.1 with MKL BLAS using VS2019 recently. The steps and dependencies I've figured out can be found at https://medium.com/@relaxli/build-mxnet-1-9-1-with-cuda-11-7-and-mkl-blas-using-visual-studio-2019-on-windows-10-a9ebecb1941b

[profK]

Thanks. In the end I went a different route for this project, but I might come back to mxnet at some point
