-```
-
-<h2 id="3">Windows</h2>
-
-On Windows, you can use [Micrsoft Visual Studio 2015](https://www.visualstudio.com/vs/older-downloads/) and [Microsoft Visual Studio 2017](https://www.visualstudio.com/downloads/) to compile MXNet with Intel MKL-DNN.
-[Micrsoft Visual Studio 2015](https://www.visualstudio.com/vs/older-downloads/) is recommended.
-
-**Visual Studio 2015**
-
-To build and install MXNet yourself, you need the following dependencies. Install the required dependencies:
-
-1. If [Microsoft Visual Studio 2015](https://www.visualstudio.com/vs/older-downloads/) is not already installed, download and install it. You can download and install the free community edition.
-2. Download and Install [CMake 3](https://cmake.org/) if it is not already installed.
-3. Download and install [OpenCV 3](http://sourceforge.net/projects/opencvlibrary/files/opencv-win/3.0.0/opencv-3.0.0.exe/download).
-4. Unzip the OpenCV package.
-5. Set the environment variable ```OpenCV_DIR``` to point to the ```OpenCV build directory``` (```C:\opencv\build\x64\vc14``` for example). Also, you need to add the OpenCV bin directory (```C:\opencv\build\x64\vc14\bin``` for example) to the ``PATH`` variable.
-6. If you have Intel Math Kernel Library (MKL) installed, set ```MKL_ROOT``` to point to ```MKL``` directory that contains the ```include``` and ```lib```. If you want to use MKL blas, you should set ```-DUSE_BLAS=mkl``` when cmake. Typically, you can find the directory in
-```C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2018\windows\mkl```.
-7. If you don't have the Intel Math Kernel Library (MKL) installed, download and install [OpenBLAS](http://sourceforge.net/projects/openblas/files/v0.2.14/). Note that you should also download ```mingw64.dll.zip`` along with openBLAS and add them to PATH.
-8. Set the environment variable ```OpenBLAS_HOME``` to point to the ```OpenBLAS``` directory that contains the ```include``` and ```lib``` directories. Typically, you can find the directory in ```C:\Program files (x86)\OpenBLAS\```.
-
-After you have installed all of the required dependencies, build the MXNet source code:
-
-1. Download the MXNet source code from [GitHub](https://github.com/apache/incubator-mxnet). Don't forget to pull the submodules:
-```
-git clone --recursive https://github.com/apache/incubator-mxnet.git
-```
-
-2. Copy file `3rdparty/mkldnn/config_template.vcxproj` to incubator-mxnet root.
-
-3. Start a Visual Studio command prompt.
-
-4. Use [CMake 3](https://cmake.org/) to create a Visual Studio solution in ```./build``` or some other directory. Make sure to specify the architecture in the
-[CMake 3](https://cmake.org/) command:
-```
-mkdir build
-cd build
-cmake -G "Visual Studio 14 Win64" .. -DUSE_CUDA=0 -DUSE_CUDNN=0 -DUSE_NVRTC=0 -DUSE_OPENCV=1 -DUSE_OPENMP=1 -DUSE_PROFILER=1 -DUSE_BLAS=open -DUSE_LAPACK=1 -DUSE_DIST_KVSTORE=0 -DCUDA_ARCH_NAME=All -DUSE_MKLDNN=1 -DCMAKE_BUILD_TYPE=Release
-```
-
-5. In Visual Studio, open the solution file,```.sln```, and compile it.
-These commands produce a library called ```libmxnet.dll``` in the ```./build/Release/``` or ```./build/Debug``` folder.
-Also ```libmkldnn.dll``` with be in the ```./build/3rdparty/mkldnn/src/Release/```
-
-6. Make sure that all the dll files used above(such as `libmkldnn.dll`, `libmklml.dll`, `libiomp5.dll`, `libopenblas.dll`, etc) are added to the system PATH. For convinence, you can put all of them to ```\windows\system32```. Or you will come across `Not Found Dependencies` when loading MXNet.
-
-**Visual Studio 2017**
-
-To build and install MXNet yourself using [Microsoft Visual Studio 2017](https://www.visualstudio.com/downloads/), you need the following dependencies. Install the required dependencies:
-
-1. If [Microsoft Visual Studio 2017](https://www.visualstudio.com/downloads/) is not already installed, download and install it. You can download and install the free community edition.
-2. Download and install [CMake 3](https://cmake.org/files/v3.11/cmake-3.11.0-rc4-win64-x64.msi) if it is not already installed.
-3. Download and install [OpenCV](https://sourceforge.net/projects/opencvlibrary/files/opencv-win/3.4.1/opencv-3.4.1-vc14_vc15.exe/download).
-4. Unzip the OpenCV package.
-5. Set the environment variable ```OpenCV_DIR``` to point to the ```OpenCV build directory``` (e.g., ```OpenCV_DIR = C:\utils\opencv\build```).
-6. If you don’t have the Intel Math Kernel Library (MKL) installed, download and install [OpenBlas](https://sourceforge.net/projects/openblas/files/v0.2.20/OpenBLAS%200.2.20%20version.zip/download).
-7. Set the environment variable ```OpenBLAS_HOME``` to point to the ```OpenBLAS``` directory that contains the ```include``` and ```lib``` directories (e.g., ```OpenBLAS_HOME = C:\utils\OpenBLAS```).
-
-After you have installed all of the required dependencies, build the MXNet source code:
-
-1. Start ```cmd``` in windows.
-
-2. Download the MXNet source code from GitHub by using following command:
-
-```r
-cd C:\
-git clone --recursive https://github.com/apache/incubator-mxnet.git
-```
-
-3. Copy file `3rdparty/mkldnn/config_template.vcxproj` to incubator-mxnet root.
-
-4. Follow [this link](https://docs.microsoft.com/en-us/visualstudio/install/modify-visual-studio) to modify ```Individual components```, and check ```VC++ 2017 version 15.4 v14.11 toolset```, and click ```Modify```.
-
-5. Change the version of the Visual studio 2017 to v14.11 using the following command (by default the VS2017 is installed in the following path):
-
-```r
-"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvars64.bat" -vcvars_ver=14.11
-```
-
-6. Create a build dir using the following command and go to the directory, for example:
-
-```r
-mkdir C:\build
-cd C:\build
-```
-
-7. CMake the MXNet source code by using following command:
-
-```r
-cmake -G "Visual Studio 15 2017 Win64" .. -T host=x64 -DUSE_CUDA=0 -DUSE_CUDNN=0 -DUSE_NVRTC=0 -DUSE_OPENCV=1 -DUSE_OPENMP=1 -DUSE_PROFILER=1 -DUSE_BLAS=open -DUSE_LAPACK=1 -DUSE_DIST_KVSTORE=0 -DCUDA_ARCH_NAME=All -DUSE_MKLDNN=1 -DCMAKE_BUILD_TYPE=Release
-```
-
-8. After the CMake successfully completed, compile the the MXNet source code by using following command:
-
-```r
-msbuild mxnet.sln /p:Configuration=Release;Platform=x64 /maxcpucount
-```
-
-9. Make sure that all the dll files used above(such as `libmkldnn.dll`, `libmklml.dll`, `libiomp5.dll`, `libopenblas.dll`, etc) are added to the system PATH. For convinence, you can put all of them to ```\windows\system32```. Or you will come across `Not Found Dependencies` when loading MXNet.
-
-<h2 id="4">Verify MXNet with python</h2>
-
-```
-cd python
-sudo python setup.py install
-python -c "import mxnet as mx;print((mx.nd.ones((2, 3))*2).asnumpy());"
-
-Expected Output:
-
-[[ 2. 2. 2.]
- [ 2. 2. 2.]]
-```
-
-### Verify whether MKL-DNN works
-
-After MXNet is installed, you can verify if MKL-DNN backend works well with a single Convolution layer.
-
-```
-import mxnet as mx
-import numpy as np
-
-num_filter = 32
-kernel = (3, 3)
-pad = (1, 1)
-shape = (32, 32, 256, 256)
-
-x = mx.sym.Variable('x')
-w = mx.sym.Variable('w')
-y = mx.sym.Convolution(data=x, weight=w, num_filter=num_filter, kernel=kernel, no_bias=True, pad=pad)
-exe = y.simple_bind(mx.cpu(), x=shape)
-
-exe.arg_arrays[0][:] = np.random.normal(size=exe.arg_arrays[0].shape)
-exe.arg_arrays[1][:] = np.random.normal(size=exe.arg_arrays[1].shape)
-
-exe.forward(is_train=False)
-o = exe.outputs[0]
-t = o.asnumpy()
-```
-
-More detailed debugging and profiling information can be logged by setting the environment variable 'MKLDNN_VERBOSE':
-```
-export MKLDNN_VERBOSE=1
-```
-For example, by running above code snippet, the following debugging logs providing more insights on MKL-DNN primitives `convolution` and `reorder`. That includes: Memory layout, infer shape and the time cost of primitive execution.
-```
-mkldnn_verbose,exec,reorder,jit:uni,undef,in:f32_nchw out:f32_nChw16c,num:1,32x32x256x256,6.47681

-```
-
-<h2 id="5">Enable MKL BLAS</h2>
-
-With MKL BLAS, the performace is expected to furtherly improved with variable range depending on the computation load of the models.
-You can redistribute not only dynamic libraries but also headers, examples and static libraries on accepting the license [Intel® Simplified license](https://software.intel.com/en-us/license/intel-simplified-software-license).
-Installing the full MKL installation enables MKL support for all operators under the linalg namespace.
-
- 1. Download and install the latest full MKL version following instructions on the [intel website.](https://software.intel.com/en-us/mkl)
-
- 2. Run `make -j ${nproc} USE_BLAS=mkl`
-
- 3. Navigate into the python directory
-
- 4. Run `sudo python setup.py install`
-
-### Verify whether MKL works
-
-After MXNet is installed, you can verify if MKL BLAS works well with a single dot layer.
-
-```
-import mxnet as mx
-import numpy as np
-
-shape_x = (1, 10, 8)
-shape_w = (1, 12, 8)
-
-x_npy = np.random.normal(0, 1, shape_x)
-w_npy = np.random.normal(0, 1, shape_w)
-
-x = mx.sym.Variable('x')
-w = mx.sym.Variable('w')
-y = mx.sym.batch_dot(x, w, transpose_b=True)
-exe = y.simple_bind(mx.cpu(), x=x_npy.shape, w=w_npy.shape)
-
-exe.forward(is_train=False)
-o = exe.outputs[0]
-t = o.asnumpy()
-```
-
-You can open the `MKL_VERBOSE` flag by setting environment variable:
-```
-export MKL_VERBOSE=1
-```
-Then by running above code snippet, you probably will get the following output message which means `SGEMM` primitive from MKL are called. Layout information and primitive execution performance are also demonstrated in the log message.
-```

-<h2 id="6">Enable graph optimization</h2>
-
-Graph optimization by subgraph feature are available in master branch. You can build from source and then use below command to enable this *experimental* feature for better performance:
-
-```
-export MXNET_SUBGRAPH_BACKEND=MKLDNN
-```
-
-This limitations of this experimental feature are:
-
-- Use this feature only for inference. When training, be sure to turn the feature off by unsetting the `MXNET_SUBGRAPH_BACKEND` environment variable.
-
-- This feature will only run on the CPU, even if you're using a GPU-enabled build of MXNet.

1. Download and run the [OpenCV](https://sourceforge.net/projects/opencvlibrary/files/opencv-win/3.4.1/opencv-3.4.1-vc14_vc15.exe/download) package. There are more recent versions of OpenCV, so please create an issue/PR to update this info if you validate one of these later versions.
1. This will unzip several files. You can place them in another directory if you wish. We will use `C:\utils`(```mkdir C:\utils```) as our default path.
1. Set the environment variable `OpenCV_DIR` to point to the OpenCV build directory that you just unzipped. Start ```cmd``` and type `set OpenCV_DIR=C:\utils\opencv\build`.

1. Download the [OpenBlas](https://sourceforge.net/projects/openblas/files/v0.2.19/OpenBLAS-v0.2.19-Win64-int32.zip/download) package. Later versions of OpenBLAS are available, but you would need to build from source. v0.2.19 is the most recent version that ships with binaries. Contributions of more recent binaries would be appreciated.
1. Unzip the file, rename it to ```OpenBLAS``` and put it under `C:\utils`. You can place the unzipped files and folders in another directory if you wish.
1. Set the environment variable `OpenBLAS_HOME` to point to the OpenBLAS directory that contains the `include` and `lib` directories and type `set OpenBLAS_HOME=C:\utils\OpenBLAS` on the command prompt(```cmd```).
