DependencyManager

A helper script to download and extract archives from the web. From CLI, launch the python script "MxNetDependencies.py" without any arguments. The script assumes presence of "MxNetDependencies.json" in current folder.

Specify dependencies in following form:

   {  
   
   	   "Name":"OpenBlas",	
	   "Url": "https://iweb.dl.sourceforge.net/project/openblas/v0.2.19/OpenBLAS-v0.2.19-Win64-int32.zip",
	   "DownloadToLocation":"C:\\Users\\Administrator\\MyArchives",
	   "ExtractToLocation" :"C:\\Users\\Administrator\\MyExtracts",
	   "Extractor" : "\"C:\\Program Files\\7-zip\\7z.exe\" x {} -o{} -y"
	   
   }

Note- The path names should be ecnlosed in quotes if path components contain spaces. That explains why "Extractor" value is enquoted. Also, escape back slash characters.

    2. Install.
        Choose Architecture as "x86_64"
        Choose threads as "win32"
        Choose exception as "seh" ( SEH -  structured exception handling, windows native mechanism which underlies exception handling support in C++)

B Open Blas
    1. https://iweb.dl.sourceforge.net/project/openblas/v0.2.19/OpenBLAS-v0.2.19-Win64-int32.zip
    2. Find the zip file in the downloads folder
C Open CV
    1. Download URL - https://phoenixnap.dl.sourceforge.net/project/opencvlibrary/opencv-win/3.4.1/opencv-3.4.1-vc14_vc15.exe

F. Build Mxnet library

Configure dependencies

1. create a folder called "ThirdParty" under "Work" folder created above. ( typically C:\Users\Administrator\Work)
2. Create a temp folder under "work" "C:\Users\Administrator\Work\temp"

Setup OpenBlas
    1. Extract "OpenBLAS-v0.2.19-Win64-int32.zip" under temp folder
    2. Find a folder "OpenBLAS-v0.2.19-Win64-int32" in the extracted items
    3. Copy the contents of this folder to   C:\Users\Administrator\Work\ThirdParty\OpenBlas

Setup OpenCV
    1. Extract "opencv-3.4.1-vc14_vc15.exe" under the temp folder
    2. Copy the OpenCV folder to C:\Users\Administrator\Work\ThirdParty

G. Build Command

    1. Start "VS2015 x64 Native Tools Command Prompt" from the start menu
    2. cd    "C:\Users\Administrator\Work\MxNet"
    3. cmake CMakeLists.txt -DOpenBLAS_INCLUDE_DIR=C:\Users\Administrator\Work\ThirdParty\OpenBLAS\include -DOpenBLAS_LIB=C:\Users\Administrator\Work\ThirdParty\OpenBLAS\lib\libopenblas.dll.a -DOpenCV_DIR=C:\Users\Administrator\Work\ThirdParty\opencv\build  -DUSE_CUDA=OFF -G "Visual Studio 14 2015 Win64"
    4. devenv mxnet.sln /build "Release|x64"  /project ALL_BUILD.vcxproj
