visionNoob opened a new issue #15632: Building MxNet with CPP_PACKAGE on Windows10 (2019-07-23) URL: https://github.com/apache/incubator-mxnet/issues/15632 This document gives a information about Building MxNet with CPP_PACKAGE on Windows10. If you think it is inappropriate, please close the issue. --- Hello. I'm visionNoob. I think many people are struggling with building MxNet on win10, including me. Finally, I (partially) succeed in building MxNet on win10. ### Environment Windows 10 Education Visual Studio 2015 python 3.6(7.5.0) Nvidia CUDA 9.0(V9.0.176) Intel® MKL 2019(V2019.4.245) OpenCV 4.1.0([released in 2019-04-08](https://opencv.org/releases/)) ### contents ## 1. MxNet : https://github.com/Vigilans/incubator-mxnet/tree/patch-1 (not merged yet) I cloned MxNet source from https://github.com/Vigilans/incubator-mxnet/tree/patch-1 see PR [#15144](https://github.com/apache/incubator-mxnet/pull/15144) this branch handle several issues( [#14116](https://github.com/apache/incubator-mxnet/issues/14116), [#15143](https://github.com/apache/incubator-mxnet/issues/15143) that make failure in generated op.h.) ## 2. Visual Studio 2015(vc14) I think CUDA Visual Studio Integration is also needed for stable building for cuda. And update 3 also needed. ## 3. OpenCV I use "OpenCV 4.1.0 official release version" not build from source. I tried to use OpenCV that builds myself with extra-modules but with this, fail to build mxnet. I don't know why. ## 4. Cmake version I use latest version of Cmake, 3.15.0. it's fine. ## 5. Cmake configuration my configuation is below you have to set some paths and disable/enable some options. please refer from the screen shots below.       ## 6. In my case, I generated "op.h" manually . it's very simple `OpWrapperGenerator.py` generate "op.h" in "...\incubator-mxnet\cpp-package\include\mxnet-cpp\op.h" The location of OpWrapperGenerator.py is ...\incubator-mxnet\cpp-package\scripts\OpWrapperGenerator.py go to the directory and ``` python OpWrapperGenerator.py "\your\build\Release\libmxnet.dll" ``` then "op.h" is generated in "...\incubator-mxnet\cpp-package\include\mxnet-cpp\op.h" If you see this sentences(below) during generation, You fail to generate "op.h". I say it again. I downloaded mxnet source from here(https://github.com/Vigilans/incubator-mxnet/tree/patch-1). and it maybe solve your problems. ``` 1>argument "lrs" of operator "multi_sgd_update" has unknown type ", required" 1>argument "wds" of operator "multi_sgd_update" has unknown type ", required" 1>argument "lrs" of operator "multi_sgd_mom_update" has unknown type ", required" 1>argument "wds" of operator "multi_sgd_mom_update" has unknown type ", required" 1>argument "lrs" of operator "multi_mp_sgd_update" has unknown type ", required" 1>argument "wds" of operator "multi_mp_sgd_update" has unknown type ", required" 1>argument "lrs" of operator "multi_mp_sgd_mom_update" has unknown type ", required" 1>argument "wds" of operator "multi_mp_sgd_mom_update" has unknown type ", required" ``` ## 7. Test your build!
