- <div class="cpu"><p>The following installation instructions have been tested on Ubuntu 14.04 and 16.04.</p>
-<div class="virtualenv">
-<br/><p><strong>Step 1</strong> Install virtualenv for Ubuntu.</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>$ sudo apt-get update
-$ sudo apt-get install -y python-dev python-virtualenv
-</pre></div>
-</div>
-<p><strong>Step 2</strong> Create and activate virtualenv environment for MXNet.</p>
-<p>Following command creates a virtualenv environment at <code class="docutils literal"><span class="pre">~/mxnet</span></code> directory. However, you can choose any directory by replacing <code class="docutils literal"><span class="pre">~/mxnet</span></code> with a directory of your choice.</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>$ virtualenv --system-site-packages ~/mxnet
-</pre></div>
-</div>
-<p>Activate the virtualenv environment created for <em>MXNet</em>.</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>$ <span class="nb">source</span> ~/mxnet/bin/activate

-</div>
-<p>After activating the environment, you should see the prompt as below.</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span><span class="o">(</span>mxnet<span class="o">)</span>$
-</pre></div>
-</div>
-<p><strong>Step 3</strong> Install MXNet in the active virtualenv environment.</p>
-<p>Installing <em>MXNet</em> with pip requires a latest version of <code class="docutils literal"><span class="pre">pip</span></code>. Install the latest version of <code class="docutils literal"><span class="pre">pip</span></code> by issuing the following command.</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>$ pip install --upgrade pip
-</pre></div>
-</div>
-<p>Install <em>MXNet</em> with OpenBLAS acceleration.</p>
-<p>To install MXNet 0.12.1 use the following:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>$ pip install mxnet==0.12.1 </pre></div></div>
-<p>To install MXNet 0.12.0 use the following:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>$ pip install mxnet==0.12.0 </pre></div>
-</div>
-<p><strong>Step 4</strong> Install <a class="reference external" href="http://www.graphviz.org/">Graphviz</a>. (Optional, needed for graph visualization using <code class="docutils literal"><span class="pre">mxnet.viz</span></code> package).</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>sudo apt-get install graphviz
-pip install graphviz
-</pre></div>
-</div>
-<p><strong>Step 5</strong> Validate the installation by running simple <em>MXNet</em> code described <a class="reference external" href="#validate-mxnet-installation">here</a>.</p>
-<p><strong>Note</strong> You can read more about virtualenv <a class="reference external" href="https://virtualenv.pypa.io/en/stable/userguide/">here</a>.</p>
-</div><div class="pip">
-<br/><p><strong>Step 1</strong> Install prerequisites - wget and latest pip.</p>
-<p>Installing <em>MXNet</em> with pip requires a latest version of <code class="docutils literal"><span class="pre">pip</span></code>. Install the latest version of <code class="docutils literal"><span class="pre">pip</span></code> by issuing the following command in the terminal.</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>$ sudo apt-get update
-$ sudo apt-get install -y wget python gcc
-$ wget https://bootstrap.pypa.io/get-pip.py <span class="o">&&</span> sudo python get-pip.py
-</pre></div>
-</div>
-<p><strong>Step 2</strong> Install MXNet with OpenBLAS acceleration.</p>
-<p>To install MXNet 0.12.1 use the following: </p><div class="highlight-bash"><div class="highlight"><pre><span></span><span class="o">(</span>mxnet<span class="o">)</span>$ pip install mxnet==0.12.1</pre></div> </div>
-<p>To install MXNet 0.12.0 use the following: </p><div class="highlight-bash"><div class="highlight"><pre><span></span><span class="o">(</span>mxnet<span class="o">)</span>$ pip install mxnet==0.12.0</pre></div> </div>
-<p><strong>Step 3</strong> Install <a class="reference external" href="http://www.graphviz.org/">Graphviz</a>. (Optional, needed for graph visualization using <code class="docutils literal"><span class="pre">mxnet.viz</span></code> package).</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>sudo apt-get install graphviz
-pip install graphviz
-</pre></div>
-</div>
-<p><strong>Step 4</strong> Validate the installation by running simple MXNet code described <a class="reference external" href="#validate-mxnet-installation">here</a>.</p>
-<p><strong>Experimental Choice</strong> If You would like to install mxnet with Intel MKL, try the experimental pip package with MKL:</p>
-<p>To install MXNet 0.12.1 with MKL use the following: </p><div class="highlight-bash"><div class="highlight"><pre><span></span><span class="o">(</span>mxnet<span class="o">)</span>$ pip install mxnet-mkl==0.12.1</pre></div> </div>
-<p>To install MXNet 0.12.0 with MKL use the following: </p><div class="highlight-bash"><div class="highlight"><pre><span></span><span class="o">(</span>mxnet<span class="o">)</span>$ pip install mxnet-mkl==0.12.0</pre></div> </div>
-</div><div class="docker">
-<br/><p>Docker images with <em>MXNet</em> are available at <a class="reference external" href="https://hub.docker.com/r/mxnet/">Docker Hub</a>.</p>
-<p><strong>Step 1</strong> Install Docker on your machine by following the <a class="reference external" href="https://docs.docker.com/engine/installation/linux/ubuntu/#install-using-the-repository">docker installation instructions</a>.</p>
-<p><em>Note</em> - You can install Community Edition (CE) to get started with <em>MXNet</em>.</p>
-<p><strong>Step 2</strong> [Optional] Post installation steps to manage Docker as a non-root user.</p>
-<p>Follow the four steps in this <a class="reference external" href="https://docs.docker.com/engine/installation/linux/linux-postinstall/#manage-docker-as-a-non-root-user">docker documentation</a> to allow managing docker containers without <em>sudo</em>.</p>
-<p>If you skip this step, you need to use <em>sudo</em> each time you invoke Docker.</p>
-<p><strong>Step 2</strong> Pull the MXNet docker image.</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>$ docker pull mxnet/python <span class="c1"># Use sudo if you skip Step 2</span>
-</pre></div>
-</div>
-<p>You can list docker images to see if mxnet/python docker image pull was successful.</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>$ docker images <span class="c1"># Use sudo if you skip Step 2</span>

- <div class="raspberry-pi"><p>MXNet supports the Debian based Raspbian ARM based operating system so you can run MXNet on Raspberry Pi Devices.</p>
-<p>These instructions will walk through how to build MXNet for the Raspberry Pi and install the Python bindings for the library.</p>
-<p>The complete MXNet library and its requirements can take almost 200MB of RAM, and loading large models with the library can take over 1GB of RAM. Because of this, we recommend running MXNet on the Raspberry Pi 3 or an equivalent device that has more than 1 GB of RAM and a Secure Digital (SD) card that has at least 4 GB of free memory.</p>
-<p><strong>Install MXNet</strong></p>
-<p>Installing MXNet is a two-step process:</p>
-<ol class="simple">
-<li>Build the shared library from the MXNet C++ source code.</li>
-<li>Install the supported language-specific packages for MXNet.</li>
-</ol>
-<p><strong>Step 1</strong> Build the Shared Library</p>
-<p>On Raspbian versions Wheezy and later, you need the following dependencies:</p>
-<ul class="simple">
-<li>Git (to pull code from GitHub)</li>
-<li>libblas (for linear algebraic operations)</li>
-<li>libopencv (for computer vision operations. This is optional if you want to save RAM and Disk Space)</li>
-<li>A C++ compiler that supports C++ 11. The C++ compiler compiles and builds MXNet source code. Supported compilers include the following:</li>
-<li><a class="reference external" href="https://gcc.gnu.org/gcc-4.8/">G++ (4.8 or later)</a></li>
-</ul>
-<p>Install these dependencies using the following commands in any directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo apt-get update
- sudo apt-get -y install git cmake build-essential g++-4.8 c++-4.8 liblapack* libblas* libopencv*
-</pre></div>
-</div>
-<p>Clone the MXNet source code repository using the following <code class="docutils literal"><span class="pre">git</span></code> command in your home directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> git clone https://github.com/dmlc/mxnet.git --recursive
- <span class="nb">cd</span> mxnet
-</pre></div>
-</div>
-<p>If you aren’t processing images with MXNet on the Raspberry Pi, you can minimize the size of the compiled library by building MXNet without the Open Source Computer Vision (OpenCV) library with the following commands:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">export</span> <span class="nv">USE_OPENCV</span> <span class="o">=</span> <span class="m">0</span>
- make
-</pre></div>
-</div>
-<p>Otherwise, you can build the complete MXNet library with the following command:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> make
-</pre></div>
-</div>
-<p>Executing either of these commands start the build process, which can take up to a couple hours, and creates a file called <code class="docutils literal"><span class="pre">libmxnet.so</span></code> in the mxnet/lib directory.</p>
-<p>If you are getting build errors in which the compiler is being killed, it is likely that the compiler is running out of memory (especially if you are on Raspberry Pi 1, 2 or Zero, which have less than 1GB of RAM), this can often be rectified by increasing the swapfile size on the Pi by editing the file /etc/dphys-swapfile and changing the line CONF_SWAPSIZE=100 to CONF_SWAPSIZE=1024, then running:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo /etc/init.d/dphys-swapfile stop
- sudo /etc/init.d/dphys-swapfile start
- free -m <span class="c1"># to verify the swapfile size has been increased</span>
-</pre></div>
-</div>
-<p><strong>Step 2</strong> Install MXNet Python Bindings</p>
-<p>To install python bindings run the following commands in the MXNet directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> python
- pip install --upgrade pip
- pip install -e .
-</pre></div>
-</div>
-<p>Note that the <code class="docutils literal"><span class="pre">-e</span></code> flag is optional. It is equivalent to <code class="docutils literal"><span class="pre">--editable</span></code> and means that if you edit the source files, these changes will be reflected in the package installed.</p>
-<p>You are now ready to run MXNet on your Raspberry Pi device. You can get started by following the tutorial on <a class="reference external" href="http://mxnet.io/tutorials/embedded/wine_detector.html">Real-time Object Detection with MXNet On The Raspberry Pi</a>.</p>
-<p><em>Note - Because the complete MXNet library takes up a significant amount of the Raspberry Pi’s limited RAM, when loading training data or large models into memory, you might have to turn off the GUI and terminate running processes to free RAM.</em></p>
-</div><div class="nvidia-jetson-tx2"><p>MXNet supports the Ubuntu Arch64 based operating system so you can run MXNet on NVIDIA Jetson Devices.</p>
-<p>These instructions will walk through how to build MXNet for the Pascal based <a class="reference external" href="http://www.nvidia.com/object/embedded-systems-dev-kits-modules.html">NVIDIA Jetson TX2</a> and install the corresponding python language bindings.</p>
-<p>For the purposes of this install guide we will assume that CUDA is already installed on your Jetson device.</p>
-<p><strong>Install MXNet</strong></p>
-<p>Installing MXNet is a two-step process:</p>
-<ol class="simple">
-<li>Build the shared library from the MXNet C++ source code.</li>
-<li>Install the supported language-specific packages for MXNet.</li>
-</ol>
-<p><strong>Step 1</strong> Build the Shared Library</p>
-<p>You need the following additional dependencies:</p>
-<ul class="simple">
-<li>Git (to pull code from GitHub)</li>
-<li>libatlas (for linear algebraic operations)</li>
-<li>libopencv (for computer vision operations)</li>
-<li>python pip (to load relevant python packages for our language bindings)</li>
-</ul>
-<p>Install these dependencies using the following commands in any directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo apt-get update
- sudo apt-get -y install git build-essential libatlas-base-dev libopencv-dev graphviz python-pip
- sudo pip install pip --upgrade
- sudo pip install setuptools numpy --upgrade
- sudo pip install graphviz jupyter
-</pre></div>
-</div>
-<p>Clone the MXNet source code repository using the following <code class="docutils literal"><span class="pre">git</span></code> command in your home directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> git clone https://github.com/dmlc/mxnet.git --recursive
- <span class="nb">cd</span> mxnet
-</pre></div>
-</div>
-<p>Edit the Makefile to install the MXNet with CUDA bindings to leverage the GPU on the Jetson:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> cp make/config.mk .
- <span class="nb">echo</span> <span class="s2">"USE_CUDA=1"</span> >> config.mk
- <span class="nb">echo</span> <span class="s2">"USE_CUDA_PATH=/usr/local/cuda"</span> >> config.mk
- <span class="nb">echo</span> <span class="s2">"USE_CUDNN=1"</span> >> config.mk
-</pre></div>
-</div>
-<p>Edit the Mshadow Makefile to ensure MXNet builds with Pascal’s hardware level low precision acceleration by editing mshadow/make/mshadow.mk and adding the following after line 122:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span><span class="nv">MSHADOW_CFLAGS</span> <span class="o">+=</span> -DMSHADOW_USE_PASCAL<span class="o">=</span><span class="m">1</span>
-</pre></div>
-</div>
-<p>Now you can build the complete MXNet library with the following command:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> make -j <span class="k">$(</span>nproc<span class="k">)</span>
-</pre></div>
-</div>
-<p>Executing this command creates a file called <code class="docutils literal"><span class="pre">libmxnet.so</span></code> in the mxnet/lib directory.</p>
-<p><strong>Step 2</strong> Install MXNet Python Bindings</p>
-<p>To install python bindings run the following commands in the MXNet directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> python
- pip install --upgrade pip
- pip install -e .
-</pre></div>
-</div>
-<p>Note that the <code class="docutils literal"><span class="pre">-e</span></code> flag is optional. It is equivalent to <code class="docutils literal"><span class="pre">--editable</span></code> and means that if you edit the source files, these changes will be reflected in the package installed.</p>
-<p>Add the mxnet folder to the path:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> ..
- <span class="nb">export</span> <span class="nv">MXNET_HOME</span><span class="o">=</span><span class="k">$(</span><span class="nb">pwd</span><span class="k">)</span>

-<p>Install the following NVIDIA libraries to setup <em>MXNet</em> with GPU support:</p>
-<ol class="simple">
-<li>Install CUDA 8.0 following the NVIDIA’s <a class="reference external" href="http://docs.nvidia.com/cuda/cuda-installation-guide-microsoft-windows">installation guide</a>.</li>
-<li>Install cuDNN 7 for CUDA 8.0 following the NVIDIA’s <a class="reference external" href="https://developer.nvidia.com/cudnn">installation guide</a>. You may need to register with NVIDIA for downloading the cuDNN library.</li>
-</ol>
-<p><strong>Note:</strong> Make sure to add CUDA install path to <code class="docutils literal"><span class="pre">PATH</span></code>.</p>
-<div class="pip">
-<br/><p><strong>Step 1</strong> Install python.</p>
-<p>Recommend install <code class="docutils literal"><span class="pre">Anaconda3</span></code> <a class="reference external" href="https://www.anaconda.com/download/">here</a></p>
-<p><strong>Step 2</strong> Install <em>MXNet</em> with GPU support using CUDA 8.0</p>
-<p>To install MXNet 0.12.1 use the following: </p><div class="highlight-bash"><div class="highlight"><pre><span></span><span class="o">(</span>mxnet<span class="o">)</span>$ pip install mxnet-cu80==0.12.1</pre></div> </div>

-</div>
-<div class="build-from-source">
-<br/>
-To build and install MXNet yourself, you need the following dependencies. Install the required dependencies:<ol class="simple">
-<li>If <a class="reference external" href="https://www.visualstudio.com/downloads/">Microsoft Visual Studio 2015</a> is not already installed, download and install it. You can download and install the free community edition.</li>
-<li>Download and Install <a class="reference external" href="https://cmake.org/">CMake</a> if it is not already installed.</li>
-<li>Download and install <a class="reference external" href="http://sourceforge.net/projects/opencvlibrary/files/opencv-win/3.0.0/opencv-3.0.0.exe/download">OpenCV</a>.</li>
-<li>Unzip the OpenCV package.</li>
-<li>Set the environment variable <code class="docutils literal"><span class="pre">OpenCV_DIR</span></code> to point to the <code class="docutils literal"><span class="pre">OpenCV</span> <span class="pre">build</span> <span class="pre">directory</span></code>.</li>
-<li>If you don’t have the Intel Math Kernel Library (MKL) installed, download and install <a class="reference external" href="http://sourceforge.net/projects/openblas/files/v0.2.14/">OpenBlas</a>.</li>
-<li>Set the environment variable <code class="docutils literal"><span class="pre">OpenBLAS_HOME</span></code> to point to the <code class="docutils literal"><span class="pre">OpenBLAS</span></code> directory that contains the <code class="docutils literal"><span class="pre">include</span></code> and <code class="docutils literal"><span class="pre">lib</span></code> directories. Typically, you can find the directory in <code class="docutils literal"><span class="pre">C:\Program</span> <sp [...]
-<li>Download and install <a class="reference external" href="https://developer.nvidia.com/cudnn">CuDNN</a>. To get access to the download link, register as an NVIDIA community user.</li>
-</ol>
-<p>After you have installed all of the required dependencies, build the MXNet source code:</p>
-<ol class="simple">
-<li>Download the MXNet source code from <a class="reference external" href="https://github.com/dmlc/mxnet">GitHub</a>.</li>
-<li>Use <a class="reference external" href="https://cmake.org/">CMake</a> to create a Visual Studio solution in <code class="docutils literal"><span class="pre">./build</span></code>.</li>
-<li>In Visual Studio, open the solution file,<code class="docutils literal"><span class="pre">.sln</span></code>, and compile it.
-These commands produce a library called <code class="docutils literal"><span class="pre">mxnet.dll</span></code> in the <code class="docutils literal"><span class="pre">./build/Release/</span></code> or <code class="docutils literal"><span class="pre">./build/Debug</span></code> folder.</li>
-</ol>
-<p><p> </p>
-
-Next, we install <code class="docutils literal"><span class="pre">graphviz</span></code> library that we use for visualizing network graphs you build on MXNet. We will also install <a class="reference external" href="http://jupyter.readthedocs.io/">Jupyter Notebook</a> used for running MXNet tutorials and examples.</p>
-<ul class="simple">
-<li>Install <code class="docutils literal"><span class="pre">graphviz</span></code> by downloading MSI installer from <a class="reference external" href="http://www.graphviz.org/Download_windows.php">Graphviz Download Page</a>.
-<strong>Note</strong> Make sure to add graphviz executable path to PATH environment variable. Refer <a class="reference external" href="http://stackoverflow.com/questions/35064304/runtimeerror-make-sure-the-graphviz-executables-are-on-your-systems-path-aft">here for more details</a></li>

- Apache MXNet is an effort undergoing incubation at The Apache Software Foundation (ASF), <strong>sponsored by the <i>Apache Incubator</i></strong>. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, [...]

-</div>
-<p><strong>Step 3</strong> Install OpenCV.</p>
-<p><em>MXNet</em> uses <a class="reference external" href="http://opencv.org/">OpenCV</a> for efficient image loading and augmentation operations.</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>$ sudo apt-get install -y libopencv-dev
-</pre></div>
-</div>
-<p><strong>Step 4</strong> Download MXNet sources and build MXNet core shared library. You can clone the repository as described in the following code block, or you may try the <a href="download.html">download links</a> for your desired MXNet version.</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span>$ git clone --recursive https://github.com/dmlc/mxnet

-<div class="highlight-bash"><div class="highlight"><pre><span></span>$ <span class="nb">cd</span> python
-$ pip install --upgrade pip
-$ pip install -e .
-</pre></div>
-</div>
-<p>Note that the <code class="docutils literal"><span class="pre">-e</span></code> flag is optional. It is equivalent to <code class="docutils literal"><span class="pre">--editable</span></code> and means that if you edit the source files, these changes will be reflected in the package installed.</p>
-<p><strong>Step 3</strong> Install <a class="reference external" href="http://www.graphviz.org/">Graphviz</a>. (Optional, needed for graph visualization using <code class="docutils literal"><span class="pre">mxnet.viz</span></code> package).</p>

- <div class="raspberry-pi"><p>MXNet supports the Debian based Raspbian ARM based operating system so you can run MXNet on Raspberry Pi Devices.</p>
-<p>These instructions will walk through how to build MXNet for the Raspberry Pi and install the Python bindings for the library.</p>
-<p>The complete MXNet library and its requirements can take almost 200MB of RAM, and loading large models with the library can take over 1GB of RAM. Because of this, we recommend running MXNet on the Raspberry Pi 3 or an equivalent device that has more than 1 GB of RAM and a Secure Digital (SD) card that has at least 4 GB of free memory.</p>
-<p><strong>Install MXNet</strong></p>
-<p>Installing MXNet is a two-step process:</p>
-<ol class="simple">
-<li>Build the shared library from the MXNet C++ source code.</li>
-<li>Install the supported language-specific packages for MXNet.</li>
-</ol>
-<p><strong>Step 1</strong> Build the Shared Library</p>
-<p>On Raspbian versions Wheezy and later, you need the following dependencies:</p>
-<ul class="simple">
-<li>Git (to pull code from GitHub)</li>
-<li>libblas (for linear algebraic operations)</li>
-<li>libopencv (for computer vision operations. This is optional if you want to save RAM and Disk Space)</li>
-<li>A C++ compiler that supports C++ 11. The C++ compiler compiles and builds MXNet source code. Supported compilers include the following:</li>
-<li><a class="reference external" href="https://gcc.gnu.org/gcc-4.8/">G++ (4.8 or later)</a></li>
-</ul>
-<p>Install these dependencies using the following commands in any directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo apt-get update
- sudo apt-get -y install git cmake build-essential g++-4.8 c++-4.8 liblapack* libblas* libopencv*
-</pre></div>
-</div>
-<p>Clone the MXNet source code repository using the following <code class="docutils literal"><span class="pre">git</span></code> command in your home directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> git clone https://github.com/dmlc/mxnet.git --recursive
- <span class="nb">cd</span> mxnet
-</pre></div>
-</div>
-<p>If you aren’t processing images with MXNet on the Raspberry Pi, you can minimize the size of the compiled library by building MXNet without the Open Source Computer Vision (OpenCV) library with the following commands:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">export</span> <span class="nv">USE_OPENCV</span> <span class="o">=</span> <span class="m">0</span>
- make
-</pre></div>
-</div>
-<p>Otherwise, you can build the complete MXNet library with the following command:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> make
-</pre></div>
-</div>
-<p>Executing either of these commands start the build process, which can take up to a couple hours, and creates a file called <code class="docutils literal"><span class="pre">libmxnet.so</span></code> in the mxnet/lib directory.</p>
-<p>If you are getting build errors in which the compiler is being killed, it is likely that the compiler is running out of memory (especially if you are on Raspberry Pi 1, 2 or Zero, which have less than 1GB of RAM), this can often be rectified by increasing the swapfile size on the Pi by editing the file /etc/dphys-swapfile and changing the line CONF_SWAPSIZE=100 to CONF_SWAPSIZE=1024, then running:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo /etc/init.d/dphys-swapfile stop
- sudo /etc/init.d/dphys-swapfile start
- free -m <span class="c1"># to verify the swapfile size has been increased</span>
-</pre></div>
-</div>
-<p><strong>Step 2</strong> Install MXNet Python Bindings</p>
-<p>To install python bindings run the following commands in the MXNet directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> python
- pip install --upgrade pip
- pip install -e .
-</pre></div>
-</div>
-<p>Note that the <code class="docutils literal"><span class="pre">-e</span></code> flag is optional. It is equivalent to <code class="docutils literal"><span class="pre">--editable</span></code> and means that if you edit the source files, these changes will be reflected in the package installed.</p>
-<p>You are now ready to run MXNet on your Raspberry Pi device. You can get started by following the tutorial on <a class="reference external" href="http://mxnet.io/tutorials/embedded/wine_detector.html">Real-time Object Detection with MXNet On The Raspberry Pi</a>.</p>
-<p><em>Note - Because the complete MXNet library takes up a significant amount of the Raspberry Pi’s limited RAM, when loading training data or large models into memory, you might have to turn off the GUI and terminate running processes to free RAM.</em></p>
-</div><div class="nvidia-jetson-tx2"><p>MXNet supports the Ubuntu Arch64 based operating system so you can run MXNet on NVIDIA Jetson Devices.</p>
-<p>These instructions will walk through how to build MXNet for the Pascal based <a class="reference external" href="http://www.nvidia.com/object/embedded-systems-dev-kits-modules.html">NVIDIA Jetson TX2</a> and install the corresponding python language bindings.</p>
-<p>For the purposes of this install guide we will assume that CUDA is already installed on your Jetson device.</p>
-<p><strong>Install MXNet</strong></p>
-<p>Installing MXNet is a two-step process:</p>
-<ol class="simple">
-<li>Build the shared library from the MXNet C++ source code.</li>
-<li>Install the supported language-specific packages for MXNet.</li>
-</ol>
-<p><strong>Step 1</strong> Build the Shared Library</p>
-<p>You need the following additional dependencies:</p>
-<ul class="simple">
-<li>Git (to pull code from GitHub)</li>
-<li>libatlas (for linear algebraic operations)</li>
-<li>libopencv (for computer vision operations)</li>
-<li>python pip (to load relevant python packages for our language bindings)</li>
-</ul>
-<p>Install these dependencies using the following commands in any directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo apt-get update
- sudo apt-get -y install git build-essential libatlas-base-dev libopencv-dev graphviz python-pip
- sudo pip install pip --upgrade
- sudo pip install setuptools numpy --upgrade
- sudo pip install graphviz jupyter
-</pre></div>
-</div>
-<p>Clone the MXNet source code repository using the following <code class="docutils literal"><span class="pre">git</span></code> command in your home directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> git clone https://github.com/dmlc/mxnet.git --recursive
- <span class="nb">cd</span> mxnet
-</pre></div>
-</div>
-<p>Edit the Makefile to install the MXNet with CUDA bindings to leverage the GPU on the Jetson:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> cp make/config.mk .
- <span class="nb">echo</span> <span class="s2">"USE_CUDA=1"</span> >> config.mk
- <span class="nb">echo</span> <span class="s2">"USE_CUDA_PATH=/usr/local/cuda"</span> >> config.mk
- <span class="nb">echo</span> <span class="s2">"USE_CUDNN=1"</span> >> config.mk
-</pre></div>
-</div>
-<p>Edit the Mshadow Makefile to ensure MXNet builds with Pascal’s hardware level low precision acceleration by editing mshadow/make/mshadow.mk and adding the following after line 122:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span><span class="nv">MSHADOW_CFLAGS</span> <span class="o">+=</span> -DMSHADOW_USE_PASCAL<span class="o">=</span><span class="m">1</span>
-</pre></div>
-</div>
-<p>Now you can build the complete MXNet library with the following command:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> make -j <span class="k">$(</span>nproc<span class="k">)</span>
-</pre></div>
-</div>
-<p>Executing this command creates a file called <code class="docutils literal"><span class="pre">libmxnet.so</span></code> in the mxnet/lib directory.</p>
-<p><strong>Step 2</strong> Install MXNet Python Bindings</p>
-<p>To install python bindings run the following commands in the MXNet directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> python
- pip install --upgrade pip
- pip install -e .
-</pre></div>
-</div>
-<p>Note that the <code class="docutils literal"><span class="pre">-e</span></code> flag is optional. It is equivalent to <code class="docutils literal"><span class="pre">--editable</span></code> and means that if you edit the source files, these changes will be reflected in the package installed.</p>
-<p>Add the mxnet folder to the path:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> ..
- <span class="nb">export</span> <span class="nv">MXNET_HOME</span><span class="o">=</span><span class="k">$(</span><span class="nb">pwd</span><span class="k">)</span>
- <span class="nb">echo</span> <span class="s2">"export PYTHONPATH=</span><span class="nv">$MXNET_HOME</span><span class="s2">/python:</span><span class="nv">$PYTHONPATH</span><span class="s2">"</span> >> ~/.bashrc

-<p>After you have installed all of the required dependencies, build the MXNet source code:</p>
-<ol class="simple">
-<li>Download the MXNet source code from <a class="reference external" href="https://github.com/dmlc/mxnet">GitHub</a>.</li>
-<li>Use <a class="reference external" href="https://cmake.org/">CMake</a> to create a Visual Studio solution in <code class="docutils literal"><span class="pre">./build</span></code>.</li>
-<li>In Visual Studio, open the solution file,<code class="docutils literal"><span class="pre">.sln</span></code>, and compile it.
-These commands produce a library called <code class="docutils literal"><span class="pre">mxnet.dll</span></code> in the <code class="docutils literal"><span class="pre">./build/Release/</span></code> or <code class="docutils literal"><span class="pre">./build/Debug</span></code> folder.</li>
-</ol>
-<p><p> </p>
-
-Next, we install <code class="docutils literal"><span class="pre">graphviz</span></code> library that we use for visualizing network graphs you build on MXNet. We will also install <a class="reference external" href="http://jupyter.readthedocs.io/">Jupyter Notebook</a> used for running MXNet tutorials and examples.</p>
-<ul class="simple">
-<li>Install <code class="docutils literal"><span class="pre">graphviz</span></code> by downloading MSI installer from <a class="reference external" href="http://www.graphviz.org/Download_windows.php">Graphviz Download Page</a>.

-</ol>
-<p>After you have installed all of the required dependencies, build the MXNet source code:</p>
-<ol class="simple">
-<li>Download the MXNet source code from <a class="reference external" href="https://github.com/apache/incubator-mxnet">GitHub</a>.</li>
-<li>Use <a class="reference external" href="https://cmake.org/">CMake</a> to create a Visual Studio solution in <code class="docutils literal"><span class="pre">./build</span></code>.</li>

- <div class="raspberry-pi"><p>MXNet supports the Debian based Raspbian ARM based operating system so you can run MXNet on Raspberry Pi Devices.</p>
-<p>These instructions will walk through how to build MXNet for the Raspberry Pi and install the Python bindings for the library.</p>
-<p>The complete MXNet library and its requirements can take almost 200MB of RAM, and loading large models with the library can take over 1GB of RAM. Because of this, we recommend running MXNet on the Raspberry Pi 3 or an equivalent device that has more than 1 GB of RAM and a Secure Digital (SD) card that has at least 4 GB of free memory.</p>
-<p><strong>Install MXNet</strong></p>
-<p>Installing MXNet is a two-step process:</p>
-<ol class="simple">
-<li>Build the shared library from the MXNet C++ source code.</li>
-<li>Install the supported language-specific packages for MXNet.</li>
-</ol>
-<p><strong>Step 1</strong> Build the Shared Library</p>
-<p>On Raspbian versions Wheezy and later, you need the following dependencies:</p>
-<ul class="simple">
-<li>Git (to pull code from GitHub)</li>
-<li>libblas (for linear algebraic operations)</li>
-<li>libopencv (for computer vision operations. This is optional if you want to save RAM and Disk Space)</li>
-<li>A C++ compiler that supports C++ 11. The C++ compiler compiles and builds MXNet source code. Supported compilers include the following:</li>
-<li><a class="reference external" href="https://gcc.gnu.org/gcc-4.8/">G++ (4.8 or later)</a></li>
-</ul>
-<p>Install these dependencies using the following commands in any directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo apt-get update
- sudo apt-get -y install git cmake build-essential g++-4.8 c++-4.8 liblapack* libblas* libopencv*
-</pre></div>
-</div>
-<p>Clone the MXNet source code repository using the following <code class="docutils literal"><span class="pre">git</span></code> command in your home directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> git clone https://github.com/apache/incubator-mxnet.git --recursive
- <span class="nb">cd</span> incubator-mxnet
-</pre></div>
-</div>
-<p>If you aren’t processing images with MXNet on the Raspberry Pi, you can minimize the size of the compiled library by building MXNet without the Open Source Computer Vision (OpenCV) library with the following commands:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">export</span> <span class="nv">USE_OPENCV</span> <span class="o">=</span> <span class="m">0</span>
- make
-</pre></div>
-</div>
-<p>Otherwise, you can build the complete MXNet library with the following command:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> make
-</pre></div>
-</div>
-<p>Executing either of these commands start the build process, which can take up to a couple hours, and creates a file called <code class="docutils literal"><span class="pre">libmxnet.so</span></code> in the mxnet/lib directory.</p>
-<p>If you are getting build errors in which the compiler is being killed, it is likely that the compiler is running out of memory (especially if you are on Raspberry Pi 1, 2 or Zero, which have less than 1GB of RAM), this can often be rectified by increasing the swapfile size on the Pi by editing the file /etc/dphys-swapfile and changing the line CONF_SWAPSIZE=100 to CONF_SWAPSIZE=1024, then running:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo /etc/init.d/dphys-swapfile stop
- sudo /etc/init.d/dphys-swapfile start
- free -m <span class="c1"># to verify the swapfile size has been increased</span>
-</pre></div>
-</div>
-<p><strong>Step 2</strong> Install MXNet Python Bindings</p>
-<p>To install Python bindings run the following commands in the MXNet directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> python
- pip install --upgrade pip
- pip install -e .
-</pre></div>
-</div>
-<p>Note that the <code class="docutils literal"><span class="pre">-e</span></code> flag is optional. It is equivalent to <code class="docutils literal"><span class="pre">--editable</span></code> and means that if you edit the source files, these changes will be reflected in the package installed.</p>
-<p>You are now ready to run MXNet on your Raspberry Pi device. You can get started by following the tutorial on <a class="reference external" href="http://mxnet.io/tutorials/embedded/wine_detector.html">Real-time Object Detection with MXNet On The Raspberry Pi</a>.</p>
-<p><em>Note - Because the complete MXNet library takes up a significant amount of the Raspberry Pi’s limited RAM, when loading training data or large models into memory, you might have to turn off the GUI and terminate running processes to free RAM.</em></p>
-</div><div class="nvidia-jetson-tx2"><p>MXNet supports the Ubuntu Arch64 based operating system so you can run MXNet on NVIDIA Jetson Devices.</p>
-<p>These instructions will walk through how to build MXNet for the Pascal based <a class="reference external" href="http://www.nvidia.com/object/embedded-systems-dev-kits-modules.html">NVIDIA Jetson TX2</a> and install the corresponding python language bindings.</p>
-<p>For the purposes of this install guide we will assume that CUDA is already installed on your Jetson device.</p>
-<p><strong>Install MXNet</strong></p>
-<p>Installing MXNet is a two-step process:</p>
-<ol class="simple">
-<li>Build the shared library from the MXNet C++ source code.</li>
-<li>Install the supported language-specific packages for MXNet.</li>
-</ol>
-<p><strong>Step 1</strong> Build the Shared Library</p>
-<p>You need the following additional dependencies:</p>
-<ul class="simple">
-<li>Git (to pull code from GitHub)</li>
-<li>libatlas (for linear algebraic operations)</li>
-<li>libopencv (for computer vision operations)</li>
-<li>python pip (to load relevant python packages for our language bindings)</li>
-</ul>
-<p>Install these dependencies using the following commands in any directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo apt-get update
- sudo apt-get -y install git build-essential libatlas-base-dev libopencv-dev graphviz python-pip
- sudo pip install pip --upgrade
- sudo pip install setuptools numpy --upgrade
- sudo pip install graphviz jupyter
-</pre></div>
-</div>
-<p>Clone the MXNet source code repository using the following <code class="docutils literal"><span class="pre">git</span></code> command in your home directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> git clone https://github.com/apache/incubator-mxnet.git --recursive
- <span class="nb">cd</span> incubator-mxnet
-</pre></div>
-</div>
-<p>Edit the Makefile to install the MXNet with CUDA bindings to leverage the GPU on the Jetson:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> cp make/config.mk .
- <span class="nb">echo</span> <span class="s2">"USE_CUDA=1"</span> >> config.mk
- <span class="nb">echo</span> <span class="s2">"USE_CUDA_PATH=/usr/local/cuda"</span> >> config.mk
- <span class="nb">echo</span> <span class="s2">"USE_CUDNN=1"</span> >> config.mk
-</pre></div>
-</div>
-<p>Edit the Mshadow Makefile to ensure MXNet builds with Pascal’s hardware level low precision acceleration by editing mshadow/make/mshadow.mk and adding the following after line 122:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span><span class="nv">MSHADOW_CFLAGS</span> <span class="o">+=</span> -DMSHADOW_USE_PASCAL<span class="o">=</span><span class="m">1</span>
-</pre></div>
-</div>
-<p>Now you can build the complete MXNet library with the following command:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> make -j <span class="k">$(</span>nproc<span class="k">)</span>
-</pre></div>
-</div>
-<p>Executing this command creates a file called <code class="docutils literal"><span class="pre">libmxnet.so</span></code> in the mxnet/lib directory.</p>
-<p><strong>Step 2</strong> Install MXNet Python Bindings</p>
-<p>To install Python bindings run the following commands in the MXNet directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> python
- pip install --upgrade pip
- pip install -e .
-</pre></div>
-</div>
-<p>Note that the <code class="docutils literal"><span class="pre">-e</span></code> flag is optional. It is equivalent to <code class="docutils literal"><span class="pre">--editable</span></code> and means that if you edit the source files, these changes will be reflected in the package installed.</p>
-<p>Add the mxnet folder to the path:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> ..
- <span class="nb">export</span> <span class="nv">MXNET_HOME</span><span class="o">=</span><span class="k">$(</span><span class="nb">pwd</span><span class="k">)</span>
- <span class="nb">echo</span> <span class="s2">"export PYTHONPATH=</span><span class="nv">$MXNET_HOME</span><span class="s2">/python:</span><span class="nv">$PYTHONPATH</span><span class="s2">"</span> >> ~/.bashrc
- <span class="nb">source</span> ~/.bashrc

-</ol>
-<p>After you have installed all of the required dependencies, build the MXNet source code:</p>
-<ol class="simple">
-<li>Download the MXNet source code from <a class="reference external" href="https://github.com/apache/incubator-mxnet">GitHub</a>.</li>
-<li>Use <a class="reference external" href="https://cmake.org/">CMake</a> to create a Visual Studio solution in <code class="docutils literal"><span class="pre">./build</span></code>.</li>
-<li>In Visual Studio, open the solution file,<code class="docutils literal"><span class="pre">.sln</span></code>, and compile it.
-These commands produce a library called <code class="docutils literal"><span class="pre">mxnet.dll</span></code> in the <code class="docutils literal"><span class="pre">./build/Release/</span></code> or <code class="docutils literal"><span class="pre">./build/Debug</span></code> folder.</li>
-</ol>
-<p><p> </p>

- <div class="raspberry-pi"><p>MXNet supports the Debian based Raspbian ARM based operating system so you can run MXNet on Raspberry Pi Devices.</p>
-<p>These instructions will walk through how to build MXNet for the Raspberry Pi and install the Python bindings for the library.</p>
-<p>The complete MXNet library and its requirements can take almost 200MB of RAM, and loading large models with the library can take over 1GB of RAM. Because of this, we recommend running MXNet on the Raspberry Pi 3 or an equivalent device that has more than 1 GB of RAM and a Secure Digital (SD) card that has at least 4 GB of free memory.</p>
-<p><strong>Install MXNet</strong></p>
-<p>Installing MXNet is a two-step process:</p>
-<ol class="simple">
-<li>Build the shared library from the MXNet C++ source code.</li>
-<li>Install the supported language-specific packages for MXNet.</li>
-</ol>
-<p><strong>Step 1</strong> Build the Shared Library</p>
-<p>On Raspbian versions Wheezy and later, you need the following dependencies:</p>
-<ul class="simple">
-<li>Git (to pull code from GitHub)</li>
-<li>libblas (for linear algebraic operations)</li>
-<li>libopencv (for computer vision operations. This is optional if you want to save RAM and Disk Space)</li>
-<li>A C++ compiler that supports C++ 11. The C++ compiler compiles and builds MXNet source code. Supported compilers include the following:</li>
-<li><a class="reference external" href="https://gcc.gnu.org/gcc-4.8/">G++ (4.8 or later)</a></li>
-</ul>
-<p>Install these dependencies using the following commands in any directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo apt-get update
- sudo apt-get -y install git cmake build-essential g++-4.8 c++-4.8 liblapack* libblas* libopencv*
-</pre></div>
-</div>
-<p>Clone the MXNet source code repository using the following <code class="docutils literal"><span class="pre">git</span></code> command in your home directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> git clone https://github.com/apache/incubator-mxnet.git --recursive
- <span class="nb">cd</span> incubator-mxnet
-</pre></div>
-</div>
-<p>If you aren’t processing images with MXNet on the Raspberry Pi, you can minimize the size of the compiled library by building MXNet without the Open Source Computer Vision (OpenCV) library with the following commands:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">export</span> <span class="nv">USE_OPENCV</span> <span class="o">=</span> <span class="m">0</span>
- make
-</pre></div>
-</div>
-<p>Otherwise, you can build the complete MXNet library with the following command:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> make
-</pre></div>
-</div>
-<p>Executing either of these commands start the build process, which can take up to a couple hours, and creates a file called <code class="docutils literal"><span class="pre">libmxnet.so</span></code> in the mxnet/lib directory.</p>
-<p>If you are getting build errors in which the compiler is being killed, it is likely that the compiler is running out of memory (especially if you are on Raspberry Pi 1, 2 or Zero, which have less than 1GB of RAM), this can often be rectified by increasing the swapfile size on the Pi by editing the file /etc/dphys-swapfile and changing the line CONF_SWAPSIZE=100 to CONF_SWAPSIZE=1024, then running:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo /etc/init.d/dphys-swapfile stop
- sudo /etc/init.d/dphys-swapfile start
- free -m <span class="c1"># to verify the swapfile size has been increased</span>
-</pre></div>
-</div>
-<p><strong>Step 2</strong> Install MXNet Python Bindings</p>
-<p>To install Python bindings run the following commands in the MXNet directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> python
- pip install --upgrade pip
- pip install -e .
-</pre></div>
-</div>
-<p>Note that the <code class="docutils literal"><span class="pre">-e</span></code> flag is optional. It is equivalent to <code class="docutils literal"><span class="pre">--editable</span></code> and means that if you edit the source files, these changes will be reflected in the package installed.</p>
-<p>You are now ready to run MXNet on your Raspberry Pi device. You can get started by following the tutorial on <a class="reference external" href="http://mxnet.io/tutorials/embedded/wine_detector.html">Real-time Object Detection with MXNet On The Raspberry Pi</a>.</p>
-<p><em>Note - Because the complete MXNet library takes up a significant amount of the Raspberry Pi’s limited RAM, when loading training data or large models into memory, you might have to turn off the GUI and terminate running processes to free RAM.</em></p>
-</div><div class="nvidia-jetson-tx2"><p>MXNet supports the Ubuntu Arch64 based operating system so you can run MXNet on NVIDIA Jetson Devices.</p>
-<p>These instructions will walk through how to build MXNet for the Pascal based <a class="reference external" href="http://www.nvidia.com/object/embedded-systems-dev-kits-modules.html">NVIDIA Jetson TX2</a> and install the corresponding python language bindings.</p>
-<p>For the purposes of this install guide we will assume that CUDA is already installed on your Jetson device.</p>
-<p><strong>Install MXNet</strong></p>
-<p>Installing MXNet is a two-step process:</p>
-<ol class="simple">
-<li>Build the shared library from the MXNet C++ source code.</li>
-<li>Install the supported language-specific packages for MXNet.</li>
-</ol>
-<p><strong>Step 1</strong> Build the Shared Library</p>
-<p>You need the following additional dependencies:</p>
-<ul class="simple">
-<li>Git (to pull code from GitHub)</li>
-<li>libatlas (for linear algebraic operations)</li>
-<li>libopencv (for computer vision operations)</li>
-<li>python pip (to load relevant python packages for our language bindings)</li>
-</ul>
-<p>Install these dependencies using the following commands in any directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo apt-get update
- sudo apt-get -y install git build-essential libatlas-base-dev libopencv-dev graphviz python-pip
- sudo pip install pip --upgrade
- sudo pip install setuptools numpy --upgrade
- sudo pip install graphviz jupyter
-</pre></div>
-</div>
-<p>Clone the MXNet source code repository using the following <code class="docutils literal"><span class="pre">git</span></code> command in your home directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> git clone https://github.com/apache/incubator-mxnet.git --recursive
- <span class="nb">cd</span> incubator-mxnet
-</pre></div>
-</div>
-<p>Edit the Makefile to install the MXNet with CUDA bindings to leverage the GPU on the Jetson:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> cp make/config.mk .
- <span class="nb">echo</span> <span class="s2">"USE_CUDA=1"</span> >> config.mk
- <span class="nb">echo</span> <span class="s2">"USE_CUDA_PATH=/usr/local/cuda"</span> >> config.mk
- <span class="nb">echo</span> <span class="s2">"USE_CUDNN=1"</span> >> config.mk
-</pre></div>
-</div>
-<p>Edit the Mshadow Makefile to ensure MXNet builds with Pascal’s hardware level low precision acceleration by editing mshadow/make/mshadow.mk and adding the following after line 122:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span><span class="nv">MSHADOW_CFLAGS</span> <span class="o">+=</span> -DMSHADOW_USE_PASCAL<span class="o">=</span><span class="m">1</span>
-</pre></div>
-</div>
-<p>Now you can build the complete MXNet library with the following command:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> make -j <span class="k">$(</span>nproc<span class="k">)</span>
-</pre></div>
-</div>
-<p>Executing this command creates a file called <code class="docutils literal"><span class="pre">libmxnet.so</span></code> in the mxnet/lib directory.</p>
-<p><strong>Step 2</strong> Install MXNet Python Bindings</p>
-<p>To install Python bindings run the following commands in the MXNet directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> python
- pip install --upgrade pip
- pip install -e .
-</pre></div>
-</div>
-<p>Note that the <code class="docutils literal"><span class="pre">-e</span></code> flag is optional. It is equivalent to <code class="docutils literal"><span class="pre">--editable</span></code> and means that if you edit the source files, these changes will be reflected in the package installed.</p>
-<p>Add the mxnet folder to the path:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> ..
- <span class="nb">export</span> <span class="nv">MXNET_HOME</span><span class="o">=</span><span class="k">$(</span><span class="nb">pwd</span><span class="k">)</span>
- <span class="nb">echo</span> <span class="s2">"export PYTHONPATH=</span><span class="nv">$MXNET_HOME</span><span class="s2">/python:</span><span class="nv">$PYTHONPATH</span><span class="s2">"</span> >> ~/.bashrc
- <span class="nb">source</span> ~/.bashrc

- <div class="raspberry-pi"><p>MXNet supports the Debian based Raspbian ARM based operating system so you can run MXNet on Raspberry Pi Devices.</p>
-<p>These instructions will walk through how to build MXNet for the Raspberry Pi and install the Python bindings for the library.</p>
-<p>The complete MXNet library and its requirements can take almost 200MB of RAM, and loading large models with the library can take over 1GB of RAM. Because of this, we recommend running MXNet on the Raspberry Pi 3 or an equivalent device that has more than 1 GB of RAM and a Secure Digital (SD) card that has at least 4 GB of free memory.</p>
-<p><strong>Install MXNet</strong></p>
-<p>Installing MXNet is a two-step process:</p>
-<ol class="simple">
-<li>Build the shared library from the MXNet C++ source code.</li>
-<li>Install the supported language-specific packages for MXNet.</li>
-</ol>
-<p><strong>Step 1</strong> Build the Shared Library</p>
-<p>On Raspbian versions Wheezy and later, you need the following dependencies:</p>
-<ul class="simple">
-<li>Git (to pull code from GitHub)</li>
-<li>libblas (for linear algebraic operations)</li>
-<li>libopencv (for computer vision operations. This is optional if you want to save RAM and Disk Space)</li>
-<li>A C++ compiler that supports C++ 11. The C++ compiler compiles and builds MXNet source code. Supported compilers include the following:</li>
-<li><a class="reference external" href="https://gcc.gnu.org/gcc-4.8/">G++ (4.8 or later)</a></li>
-</ul>
-<p>Install these dependencies using the following commands in any directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo apt-get update
- sudo apt-get -y install git cmake build-essential g++-4.8 c++-4.8 liblapack* libblas* libopencv*
-</pre></div>
-</div>
-<p>Clone the MXNet source code repository using the following <code class="docutils literal"><span class="pre">git</span></code> command in your home directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> git clone https://github.com/apache/incubator-mxnet.git --recursive
- <span class="nb">cd</span> incubator-mxnet
-</pre></div>
-</div>
-<p>If you aren’t processing images with MXNet on the Raspberry Pi, you can minimize the size of the compiled library by building MXNet without the Open Source Computer Vision (OpenCV) library with the following commands:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">export</span> <span class="nv">USE_OPENCV</span> <span class="o">=</span> <span class="m">0</span>
- make
-</pre></div>
-</div>
-<p>Otherwise, you can build the complete MXNet library with the following command:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> make
-</pre></div>
-</div>
-<p>Executing either of these commands start the build process, which can take up to a couple hours, and creates a file called <code class="docutils literal"><span class="pre">libmxnet.so</span></code> in the mxnet/lib directory.</p>
-<p>If you are getting build errors in which the compiler is being killed, it is likely that the compiler is running out of memory (especially if you are on Raspberry Pi 1, 2 or Zero, which have less than 1GB of RAM), this can often be rectified by increasing the swapfile size on the Pi by editing the file /etc/dphys-swapfile and changing the line CONF_SWAPSIZE=100 to CONF_SWAPSIZE=1024, then running:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo /etc/init.d/dphys-swapfile stop
- sudo /etc/init.d/dphys-swapfile start
- free -m <span class="c1"># to verify the swapfile size has been increased</span>
-</pre></div>
-</div>
-<p><strong>Step 2</strong> Install MXNet Python Bindings</p>
-<p>To install Python bindings run the following commands in the MXNet directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> python
- pip install --upgrade pip
- pip install -e .
-</pre></div>
-</div>
-<p>Note that the <code class="docutils literal"><span class="pre">-e</span></code> flag is optional. It is equivalent to <code class="docutils literal"><span class="pre">--editable</span></code> and means that if you edit the source files, these changes will be reflected in the package installed.</p>
-<p>You are now ready to run MXNet on your Raspberry Pi device. You can get started by following the tutorial on <a class="reference external" href="http://mxnet.io/tutorials/embedded/wine_detector.html">Real-time Object Detection with MXNet On The Raspberry Pi</a>.</p>
-<p><em>Note - Because the complete MXNet library takes up a significant amount of the Raspberry Pi’s limited RAM, when loading training data or large models into memory, you might have to turn off the GUI and terminate running processes to free RAM.</em></p>
-</div> <!-- End of raspberry pi --><div class="nvidia-jetson-tx2"><p>MXNet supports the Ubuntu Arch64 based operating system so you can run MXNet on NVIDIA Jetson Devices.</p>
-<p>These instructions will walk through how to build MXNet for the Pascal based <a class="reference external" href="http://www.nvidia.com/object/embedded-systems-dev-kits-modules.html">NVIDIA Jetson TX2</a> and install the corresponding python language bindings.</p>
-<p>For the purposes of this install guide we will assume that CUDA is already installed on your Jetson device.</p>
-<p><strong>Install MXNet</strong></p>
-<p>Installing MXNet is a two-step process:</p>
-<ol class="simple">
-<li>Build the shared library from the MXNet C++ source code.</li>
-<li>Install the supported language-specific packages for MXNet.</li>
-</ol>
-<p><strong>Step 1</strong> Build the Shared Library</p>
-<p>You need the following additional dependencies:</p>
-<ul class="simple">
-<li>Git (to pull code from GitHub)</li>
-<li>libatlas (for linear algebraic operations)</li>
-<li>libopencv (for computer vision operations)</li>
-<li>python pip (to load relevant python packages for our language bindings)</li>
-</ul>
-<p>Install these dependencies using the following commands in any directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> sudo apt-get update
- sudo apt-get -y install git build-essential libatlas-base-dev libopencv-dev graphviz python-pip
- sudo pip install pip --upgrade
- sudo pip install setuptools numpy --upgrade
- sudo pip install graphviz jupyter
-</pre></div>
-</div>
-<p>Clone the MXNet source code repository using the following <code class="docutils literal"><span class="pre">git</span></code> command in your home directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> git clone https://github.com/apache/incubator-mxnet.git --recursive
- <span class="nb">cd</span> incubator-mxnet
-</pre></div>
-</div>
-<p>Edit the Makefile to install the MXNet with CUDA bindings to leverage the GPU on the Jetson:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> cp make/config.mk .
- <span class="nb">echo</span> <span class="s2">"USE_CUDA=1"</span> >> config.mk
- <span class="nb">echo</span> <span class="s2">"USE_CUDA_PATH=/usr/local/cuda"</span> >> config.mk
- <span class="nb">echo</span> <span class="s2">"USE_CUDNN=1"</span> >> config.mk
-</pre></div>
-</div>
-<p>Edit the Mshadow Makefile to ensure MXNet builds with Pascal’s hardware level low precision acceleration by editing 3rdparty/mshadow/make/mshadow.mk and adding the following after line 122:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span><span class="nv">MSHADOW_CFLAGS</span> <span class="o">+=</span> -DMSHADOW_USE_PASCAL<span class="o">=</span><span class="m">1</span>
-</pre></div>
-</div>
-<p>Now you can build the complete MXNet library with the following command:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> make -j <span class="k">$(</span>nproc<span class="k">)</span>
-</pre></div>
-</div>
-<p>Executing this command creates a file called <code class="docutils literal"><span class="pre">libmxnet.so</span></code> in the mxnet/lib directory.</p>
-<p><strong>Step 2</strong> Install MXNet Python Bindings</p>
-<p>To install Python bindings run the following commands in the MXNet directory:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> python
- pip install --upgrade pip
- pip install -e .
-</pre></div>
-</div>
-<p>Note that the <code class="docutils literal"><span class="pre">-e</span></code> flag is optional. It is equivalent to <code class="docutils literal"><span class="pre">--editable</span></code> and means that if you edit the source files, these changes will be reflected in the package installed.</p>
-<p>Add the mxnet folder to the path:</p>
-<div class="highlight-bash"><div class="highlight"><pre><span></span> <span class="nb">cd</span> ..
- <span class="nb">export</span> <span class="nv">MXNET_HOME</span><span class="o">=</span><span class="k">$(</span><span class="nb">pwd</span><span class="k">)</span>
- <span class="nb">echo</span> <span class="s2">"export PYTHONPATH=</span><span class="nv">$MXNET_HOME</span><span class="s2">/python:</span><span class="nv">$PYTHONPATH</span><span class="s2">"</span> >> ~/.bashrc
