 <span id="installing-mxnet-on-ubuntu"></span><h1>Installing MXNet on Ubuntu<a class="headerlink" href="#installing-mxnet-on-ubuntu" title="Permalink to this headline">¶</a></h1>
 <p><strong>NOTE:</strong> For MXNet with Python installation, please refer to the <a class="reference external" href="http://mxnet.io/get_started/install.html">new install guide</a>.</p>
 <p>MXNet currently supports Python, R, Julia, Scala, and Perl. For users of R on Ubuntu operating systems, MXNet provides a set of Git Bash scripts that installs all of the required MXNet dependencies and the MXNet library.</p>
 <p>The simple installation scripts set up MXNet for Python and R on computers running Ubuntu 12 or later. The scripts install MXNet in your home folder <code class="docutils literal"><span class="pre">~/mxnet</span></code>.</p>

 <span id="prepare-environment-for-gpu-installation"></span><h2>Prepare environment for GPU Installation<a class="headerlink" href="#prepare-environment-for-gpu-installation" title="Permalink to this headline">¶</a></h2>
 <p>If you plan to build with GPU, you need to set up the environment for CUDA and CUDNN.</p>
 <p>First, download and install <a class="reference external" href="https://developer.nvidia.com/cuda-toolkit">CUDA 8 toolkit</a>.</p>
 <p>Then download <a class="reference external" href="https://developer.nvidia.com/cudnn">cudnn 6</a>.</p>
 <p>Unzip the file and change to the cudnn root directory. Move the header and libraries to your local CUDA Toolkit folder:</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>    tar xvzf cudnn-8.0-linux-x64-v6.0.tgz
     sudo cp -P cuda/include/cudnn.h /usr/local/cuda/include
     sudo cp -P cuda/lib64/libcudnn* /usr/local/cuda/lib64
     sudo chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*
     sudo ldconfig
 </pre></div>
 </div>
 <p>Finally, add configurations to config.mk file:</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>    cp make/config.mk .
 </pre></div>
 </div>

 <span id="install-mxnet-for-r"></span><h3>Install MXNet for R<a class="headerlink" href="#install-mxnet-for-r" title="Permalink to this headline">¶</a></h3>
 <p>MXNet requires R-version to be 3.2.0 and above. If you are running an earlier version of R, run below commands to update your R version, before running the installation script.</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9
     sudo add-apt-repository ppa:marutter/rdev

     sudo apt-get update
     sudo apt-get upgrade
     sudo apt-get install r-base r-base-dev
 </pre></div>
 </div>
 <p>To install MXNet for R:</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>    <span class="c1"># Clone mxnet repository. In terminal, run the commands WITHOUT "sudo"</span>
     git clone https://github.com/dmlc/mxnet.git ~/mxnet --recursive

     <span class="nb">cd</span> ~/mxnet
     cp make/config.mk .
     <span class="c1"># If building with GPU, add configurations to config.mk file:</span>

 </pre></div>
 </div>
 <p>The installation script to install MXNet for R can be found <a class="reference external" href="https://raw.githubusercontent.com/dmlc/mxnet/master/setup-utils/install-mxnet-ubuntu-r.sh">here</a>.</p>

 <div class="section" id="standard-installation">
 <span id="standard-installation"></span><h2>Standard installation<a class="headerlink" href="#standard-installation" title="Permalink to this headline">¶</a></h2>
 <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>Note:</strong> To change the compilation options for your build, edit the <code class="docutils literal"><span class="pre">make/config.mk</span></code> file and submit a build request with the <code class="docutils literal"><span class="pre">make</span></code> command.</p>
 <div class="section" id="build-the-shared-library">
 <span id="build-the-shared-library"></span><h3>Build the Shared Library<a class="headerlink" href="#build-the-shared-library" title="Permalink to this headline">¶</a></h3>
 <p>On Ubuntu versions 13.10 or later, you need the following dependencies:</p>
 <p><strong>Step 1</strong> Install build tools and git.</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>    sudo apt-get update
     sudo apt-get install -y build-essential git
 </pre></div>
 </div>
 <p><strong>Step 2</strong> Install OpenBLAS.</p>
 <p><em>MXNet</em> uses <a class="reference external" href="https://en.wikipedia.org/wiki/Basic_Linear_Algebra_Subprograms">BLAS</a> library for accelerated numerical computations on CPU machine. There are several flavors of BLAS libraries - <a class="reference external" href="http://www.openblas.net/">OpenBLAS</a>, <a class="reference external" href="http://math-atlas.sourceforge.net/">ATLAS</a> and <a class="reference external" href="https://software.intel.com/en-us/intel-mkl">MKL</a>. In this step we install OpenBLAS. You can choose to install ATLAS or MKL.</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>    sudo apt-get install -y libopenblas-dev
 </pre></div>
 </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.</p>
 <p>If building on CPU:</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>    git clone --recursive https://github.com/dmlc/mxnet
     <span class="nb">cd</span> mxnet
     make -j <span class="k">$(</span>nproc<span class="k">)</span> <span class="nv">USE_OPENCV</span><span class="o">=</span><span class="m">1</span> <span class="nv">USE_BLAS</span><span class="o">=</span>openblas
 </pre></div>
 </div>
 <p>If building on GPU:</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>    git clone --recursive https://github.com/dmlc/mxnet
     <span class="nb">cd</span> mxnet
     make -j <span class="k">$(</span>nproc<span class="k">)</span> <span class="nv">USE_OPENCV</span><span class="o">=</span><span class="m">1</span> <span class="nv">USE_BLAS</span><span class="o">=</span>openblas <span class="nv">USE_CUDA</span><span class="o">=</span><span class="m">1</span> <span class="nv">USE_CUDA_PATH</span><span class="o">=</span>/usr/local/cuda <span class="nv">USE_CUDNN</span><span class="o">=</span><span class="m">1</span>
 </pre></div>
 </div>
 <p><em>Note</em> - USE_OPENCV and USE_BLAS are make file flags to set compilation options to use OpenCV and BLAS library. You can explore and use more compilation options in <code class="docutils literal"><span class="pre">make/config.mk</span></code>.</p>
 <p>Executing these commands creates a library called <code class="docutils literal"><span class="pre">libmxnet.so</span></code>.</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>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>    sudo apt-get install -y python-pip
     sudo pip install graphviz
     sudo pip install Jupyter
 </pre></div>
 </div>
 <p><p> </p>
 </p>
 <p>We have installed MXNet core library. Next, we will install MXNet interface package for programming language of your choice:</p>

     <span class="nb">cd</span> ..
     make rpkg
 </pre></div>
 </div>
 <p><strong>Note:</strong> R-package is a folder in the MXNet source.</p>
 <p>These commands create the MXNet R package as a tar.gz file that you can install as an R package. To install the R package, run the following command, use your MXNet version number:</p>

 <div class="highlight-bash"><div class="highlight"><pre><span></span>    <span class="nb">export</span> <span class="nv">MXNET_HOME</span><span class="o">=</span>/<path to>/libmxnet
 </pre></div>
 </div>
 <p>The path to the existing libmxnet installation should be the root directory of libmxnet. In other words, you should be able to find the <code class="docutils literal"><span class="pre">libmxnet.so</span></code> file at <code class="docutils literal"><span class="pre">$MXNET_HOME/lib</span></code>. For example, if the root directory of libmxnet is <code class="docutils literal"><span class="pre">~</span></code>, you would run the following command:</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>    <span class="nb">export</span> <span class="nv">MXNET_HOME</span><span class="o">=</span>/~/libmxnet
 </pre></div>
 </div>
 <p>You might want to add this command to your <code class="docutils literal"><span class="pre">~/.bashrc</span></code> file. If you do, you can install the Julia package in the Julia console using the following command:</p>
 <div class="highlight-julia"><div class="highlight"><pre><span></span>    <span class="n">Pkg</span><span class="o">.</span><span class="n">add</span><span class="p">(</span><span class="s">"MXNet"</span><span class="p">)</span>
 </pre></div>
 </div>

 <p>There are two ways to install the MXNet package for Scala:</p>
 <ul class="simple">
 <li>Use the prebuilt binary package</li>
 <li>Build the library from source code</li>
 </ul>
 <div class="section" id="use-the-prebuilt-binary-package">
 <span id="use-the-prebuilt-binary-package"></span><h4>Use the Prebuilt Binary Package<a class="headerlink" href="#use-the-prebuilt-binary-package" title="Permalink to this headline">¶</a></h4>
 <p>For Linux users, MXNet provides prebuilt binary packages that support computers with either GPU or CPU processors. To download and build these packages using <code class="docutils literal"><span class="pre">Maven</span></code>, change the <code class="docutils literal"><span class="pre">artifactId</span></code> in the following Maven dependency to match your architecture:</p>
 <div class="highlight-HTML"><div class="highlight"><pre><span></span><span class="p"><</span><span class="nt">dependency</span><span class="p">></span>
   <span class="p"><</span><span class="nt">groupId</span><span class="p">></span>ml.dmlc.mxnet<span class="p"></</span><span class="nt">groupId</span><span class="p">></span>
   <span class="p"><</span><span class="nt">artifactId</span><span class="p">></span>mxnet-full_<span class="p"><</span><span class="nt">system</span> <span class="na">architecture</span><span class="p">></</span><span class="nt">artifactId</span><span class="p">></span>
   <span class="p"><</span><span class="nt">version</span><span class="p">></span>0.1.1<span class="p"></</span><span class="nt">version</span><span class="p">></span>
 <span class="p"></</span><span class="nt">dependency</span><span class="p">></span>
 </pre></div>
 </div>
 <p>For example, to download and build the 64-bit CPU-only version for Linux, use:</p>
 <div class="highlight-HTML"><div class="highlight"><pre><span></span><span class="p"><</span><span class="nt">dependency</span><span class="p">></span>
   <span class="p"><</span><span class="nt">groupId</span><span class="p">></span>ml.dmlc.mxnet<span class="p"></</span><span class="nt">groupId</span><span class="p">></span>
   <span class="p"><</span><span class="nt">artifactId</span><span class="p">></span>mxnet-full_2.10-linux-x86_64-cpu<span class="p"></</span><span class="nt">artifactId</span><span class="p">></span>
   <span class="p"><</span><span class="nt">version</span><span class="p">></span>0.1.1<span class="p"></</span><span class="nt">version</span><span class="p">></span>
 <span class="p"></</span><span class="nt">dependency</span><span class="p">></span>
 </pre></div>
 </div>
 <p>If your native environment differs slightly from the assembly package, for example, if you use the openblas package instead of the atlas package, it’s better to use the mxnet-core package and put the compiled Java native library in your load path:</p>
 <div class="highlight-HTML"><div class="highlight"><pre><span></span><span class="p"><</span><span class="nt">dependency</span><span class="p">></span>
   <span class="p"><</span><span class="nt">groupId</span><span class="p">></span>ml.dmlc.mxnet<span class="p"></</span><span class="nt">groupId</span><span class="p">></span>
   <span class="p"><</span><span class="nt">artifactId</span><span class="p">></span>mxnet-core_2.10<span class="p"></</span><span class="nt">artifactId</span><span class="p">></span>
   <span class="p"><</span><span class="nt">version</span><span class="p">></span>0.1.1<span class="p"></</span><span class="nt">version</span><span class="p">></span>
 <span class="p"></</span><span class="nt">dependency</span><span class="p">></span>

 <p>Before you build MXNet for Scala from source code, you must complete <a class="reference external" href="#build-the-shared-library">building the shared library</a>. After you build the shared library, run the following command from the MXNet source root directory to build the MXNet Scala package:</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>    make scalapkg
 </pre></div>
 </div>
 <p>This command creates the JAR files for the assembly, core, and example modules. It also creates the native library in the <code class="docutils literal"><span class="pre">native/{your-architecture}/target</span> <span class="pre">directory</span></code>, which you can use to cooperate with the core module.</p>
 <p>To install the MXNet Scala package into your local Maven repository, run the following command from the MXNet source root directory:</p>
 <div class="highlight-bash"><div class="highlight"><pre><span></span>    make scalainstall
