| <h1 id="installing-mxnet-from-source-on-ubuntu">Installing MXNet from source on Ubuntu</h1> |
| |
| <p>The following installation instructions are for building MXNet from source on |
| computers running <strong>Ubuntu 16.04</strong> or higher. For instructions to build MXNet |
| from source on other platforms, see the general <a href="build_from_source">Build From Source |
| guide</a>.</p> |
| |
| <p>Instead of building from source, you can install a binary version of MXNet. For |
| that, please follow the information at <a href="get_started">Get Started</a>.</p> |
| |
| <p>Building MXNet from source is a two-step process:</p> |
| |
| <ol> |
| <li>Build the shared library from the MXNet C++ source code.</li> |
| <li>(optional) Install the supported language-specific packages for MXNet.</li> |
| </ol> |

| <h2 id="cuda-dependencies">CUDA Dependencies</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 href="https://developer.nvidia.com/cuda-toolkit">CUDA toolkit</a>. CUDA 9.2 is recommended.</p> |
| |
| <p>Then download <a href="https://developer.nvidia.com/cudnn">cuDNN 7.1.4</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"><pre><code class="language-bash" data-lang="bash"><span class="nb">tar </span>xvzf cudnn-9.2-linux-x64-v7.1 |
| <span class="nb">sudo cp</span> <span class="nt">-P</span> cuda/include/cudnn.h /usr/local/cuda/include |
| <span class="nb">sudo cp</span> <span class="nt">-P</span> cuda/lib64/libcudnn<span class="k">*</span> /usr/local/cuda/lib64 |
| <span class="nb">sudo chmod </span>a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn<span class="k">*</span> |
| <span class="nb">sudo </span>ldconfig |
| </code></pre></div> |
| <p><hr></p> |
| |
| <h2 id="build-the-mxnet-shared-library-from-source">Build the MXNet shared library from source</h2> |
| |
| <p>It is recommended that you review the general <a href="build_from_source">build from source</a> instructions before continuing.</p> |
| |
| <p>On Ubuntu versions 16.04 or later, you need the following dependencies:</p> |
| |
| <p><strong>Step 1:</strong> Install prerequisite packages.</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">sudo </span>apt-get update |
| <span class="nb">sudo </span>apt-get <span class="nb">install</span> <span class="nt">-y</span> build-essential git ninja-build ccache libopenblas-dev libopencv-dev cmake |
| </code></pre></div> |
| <p>Instead of <code>libopenblas-dev</code> you may also choose a different math library. |
| Further information is provided in the source guide's <a href="build_from_source#math-library-selection">Math Library |
| Selection</a> section.</p> |
| |
| <p><code>libopencv-dev</code> is an optional dependency. You can delete it from above <code>apt-get |
| install</code> line and build MXNet without OpenCV support by setting <code>USE_OPENCV</code> to |
| <code>OFF</code> in the configuration file described below.</p> |
| |
| <p>Note: CMake 3.13 or higher is required. If you are running an older version of |
| CMake, you will see an error message like <code>CMake 3.13 or higher is required. You |
| are running version 3.10.2</code> during Step 3. In that case please update CMake on |
| your system. You can download and install latest CMake from <a href="https://cmake.org">https://cmake.org</a> or |
| via <code>pip3</code> with <code>pip3 install --user --upgrade "cmake>=3.13.2"</code>. If <code>pip3</code> is |
| not available on your system, you can install it via <code>sudo apt-get install -y |
| python3-pip</code>. After installing cmake with <code>pip3</code>, it is usually available at |
| <code>~/.local/bin/cmake</code> or directly as <code>cmake</code>.</p> |
| |
| <p><strong>Step 2:</strong> Download MXNet sources and configure</p> |
| |
| <p>Clone the repository:</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash">git clone <span class="nt">--recursive</span> https://github.com/apache/mxnet.git mxnet |
| <span class="nb">cd </span>mxnet |
| <span class="nb">cp </span>config/linux.cmake config.cmake <span class="c"># or config/linux_gpu.cmake for build with CUDA</span> |
| </code></pre></div> |
| <p>Please edit the config.cmake file based on your needs. The file contains a |
| series of <code>set(name value CACHE TYPE "Description")</code> entries. You can change the |
| values of the respective <code>value</code>.</p> |
| |
| <p>For a GPU-enabled build make sure you have installed the <a href="#cuda-dependencies">CUDA dependencies |
| first</a>). When building a GPU-enabled build on a machine |
| without GPU, MXNet build can't autodetect your GPU architecture and will target |
| all available GPU architectures. Please set the <code>MXNET_CUDA_ARCH</code> variable in |
| <code>config.cmake</code> to your desired cuda architecture to speed up the build.</p> |
| |
| <p>To (optionally) build with MKL math library, please install MKL first based on |
| the guide in <a href="build_from_source#math-library-selection">Math Library Selection</a>.</p> |
| |
| <p><strong>Step 3:</strong> Build MXNet core shared library.</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">rm</span> <span class="nt">-rf</span> build |
| <span class="nb">mkdir</span> <span class="nt">-p</span> build <span class="o">&&</span> <span class="nb">cd </span>build |
| cmake .. |
| cmake <span class="nt">--build</span> <span class="nb">.</span> |
| </code></pre></div> |
| <p>Specify <code>cmake --build . --parallel N</code> to set the number of parallel compilation |
| jobs. Default is derived from CPUs available.</p> |
| |
| <p>After a successful build, you will find the <code>libmxnet.so</code> in the <code>build</code> folder |
| in your MXNet project root. <code>libmxnet.so</code> is required to install language |
| bindings described in the next section.</p> |
| |
| <p><hr></p> |
| |
| <h2 id="installing-language-packages-for-mxnet">Installing Language Packages for MXNet</h2> |
| |
| <p>After you have installed the MXNet core library. You may install MXNet interface |
| packages for the programming language of your choice: |
| - <a href="#install-mxnet-for-python">Python</a> |
| - <a href="#install-the-mxnet-package-for-c++">C++</a> |
| - <a href="#install-the-mxnet-package-for-clojure">Clojure</a> |

| - <a href="#install-the-mxnet-package-for-scala">Scala</a> |
| - <a href="#install-the-mxnet-package-for-java">Java</a></p> |
| |
| <p><hr></p> |
| |
| <h3 id="install-mxnet-for-python">Install MXNet for Python</h3> |
| |
| <p>To install the MXNet Python binding navigate to the root of the MXNet folder then run the following:</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">cd </span>python |
| pip <span class="nb">install</span> <span class="nt">--user</span> <span class="nt">-e</span> <span class="nb">.</span> |
| </code></pre></div> |
| <p>Note that the <code>-e</code> flag is optional. It is equivalent to <code>--editable</code> and means |
| that if you edit the source files, these changes will be reflected in the |
| package installed.</p> |
| |
| <h4 id="optional-python-packages">Optional Python Packages</h4> |
| |
| <p>You may optionally install <code>graphviz</code> library that is used for visualizing network graphs you build on MXNet. You |
| may also install <a href="http://jupyter.readthedocs.io/">Jupyter Notebook</a> which is used for running MXNet tutorials and |
| examples.</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash">pip <span class="nb">install</span> <span class="nt">--user</span> <span class="nv">graphviz</span><span class="o">==</span>0.8.4 jupyter |

| <p>The package available through <code>apt-get</code> is old and not compatible with the latest version of MXNet. |
| Fetch the latest version (1.0.3 at the time of this writing).</p> |

| julia <span class="nt">-e</span> <span class="s1">'using InteractiveUtils; versioninfo()'</span> |
| </code></pre></div> |
| <p>If you're still getting the old version, remove it.</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">sudo </span>apt remove julia |
| </code></pre></div> |
| <p>Update your PATH to have Julia's new location. Add this to your <code>.zshrc</code>, <code>.bashrc</code>, <code>.profile</code> or <code>.bash_profile</code>.</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">export </span><span class="nv">PATH</span><span class="o">=</span>~/julia/julia-1.0.3/bin:<span class="nv">$PATH</span> |

| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">echo</span> <span class="nv">$PATH</span> |

| <p>Validate Julia works and is the expected version.</p> |

| </code></pre></div> |
| <h4 id="setup-your-mxnet-julia-environment">Setup Your MXNet-Julia Environment</h4> |
| |
| <p><strong>For each of the following environment variables, add the commands to your <code>.zshrc</code>, <code>.bashrc</code>, <code>.profile</code> |
| or <code>.bash_profile</code> to make them persist.</strong></p> |
| |
| <p>Create a <code>julia-depot</code> folder and environment variable.</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">mkdir </span>julia-depot |
| <span class="nb">export </span><span class="nv">JULIA_DEPOT_PATH</span><span class="o">=</span><span class="nv">$HOME</span>/julia/julia-depot |
| </code></pre></div> |
| <p>To use the Julia binding with an existing <code>libmxnet</code> installation, set the <code>MXNET_HOME</code> environment variable to the |
| MXNet source root. For example:</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">export </span><span class="nv">MXNET_HOME</span><span class="o">=</span><span class="nv">$HOME</span>/mxnet |
| </code></pre></div> |
| <p>Now set the <code>LD_LIBRARY_PATH</code> environment variable to where <code>libmxnet.so</code> is found. If you can't find it, you might |
| have skipped the building MXNet step. Go back and <a href="#build-the-shared-library">build MXNet</a> first. For example:</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">export </span><span class="nv">LD_LIBRARY_PATH</span><span class="o">=</span><span class="nv">$HOME</span>/mxnet/lib:<span class="nv">$LD_LIBRARY_PATH</span> |
| </code></pre></div> |
| <p>Verify the location of <code>libjemalloc.so</code> and set the <code>LD_PRELOAD</code> environment variable. |
| <code>bash |
| export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so:$LD_PRELOAD |
| </code></p> |
| |
| <p>With all of these updates, here's an example of what you might want to have in your <code>.zshrc</code>, <code>.bashrc</code>, <code>.profile</code> |
| or <code>.bash_profile</code>.</p> |
| <div class="highlight"><pre><code class="language-" data-lang="">export PATH=$HOME/bin:$HOME/.local/bin:$HOME/julia/julia-1.0.3/bin:$PATH |

| <h3 id="install-the-mxnet-package-for-r">Install the MXNet Package for R</h3> |
| |
| <p>Before you build MXNet for R from source code, you must complete |
| <a href="#build-the-shared-library">building the shared library</a>.</p> |
| |
| <p><strong>Minimum Requirements</strong> |
| 1. <a href="https://gcc.gnu.org/gcc-4.8/">GCC 4.8</a> or later to compile C++ 11. |
| 2. <a href="https://www.gnu.org/software/make/">GNU Make</a></p> |
| |
| <p><br/></p> |
| |
| <p><strong>Build the MXNet core shared library</strong></p> |
| |
| <p><strong>Step 1</strong> Install R, cran-devtools and dependencies</p> |
| |
| <p>To install R and the devtools, run</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">sudo </span>apt-get update |
| <span class="nb">sudo </span>apt-get <span class="nb">install</span> <span class="nt">-y</span> r-base-core r-cran-devtools libcairo2-dev libxml2-dev |
| </code></pre></div> |
| <p><code>libxml2-dev</code> is required for the <code>roxygen2</code> dependency and <code>libcairo2-dev</code> is |
| required for the suggested <code>imager</code> dependency.</p> |
| |
| <p>To generate documentation, it is also required to install <code>roxygen2</code>.</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash">R |
| <span class="o">></span> install.packages<span class="o">(</span><span class="s2">"roxygen2"</span><span class="o">)</span> |

| </code></pre></div> |
| <p>Note: To successfully complete the next step, you need a personal R library. If |
| you were able to run <code>install.packages("roxygen2")</code> above, you either had |
| already, or you have successfully created a personal library just now.</p> |
| |
| <p><strong>Step 2</strong> Make and install the MXNet-R bindings.</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash">make <span class="nt">-f</span> R-package/Makefile rpkg |
| </code></pre></div> |
| <h4 id="verify-mxnet-r-installation">Verify MXNet-R Installation</h4> |
| |
| <p>You can verify your MXNet-R installation as follows:</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash">R |
| </code></pre></div> |
| <p>At the R prompt enter the following:</p> |
| <div class="highlight"><pre><code class="language-r" data-lang="r"><span class="n">library</span><span class="p">(</span><span class="n">mxnet</span><span class="p">)</span><span class="w"> |
