| <h1 id="installing-mxnet-on-centos-and-other-non-ubuntu-linux-systems">Installing MXNet on CentOS and other non-Ubuntu Linux systems</h1> |
| |
| <p>Step 1. Install build tools and git on <code>CentOS >= 7</code> and <code>Fedora >= 19</code>:</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">sudo </span>yum groupinstall <span class="nt">-y</span> <span class="s2">"Development Tools"</span> <span class="o">&&</span> <span class="nb">sudo </span>yum <span class="nb">install</span> <span class="nt">-y</span> git |
| </code></pre></div> |
| <p>Step 2. Install Atlas:</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">sudo </span>yum <span class="nb">install </span>atlas-devel |
| </code></pre></div> |
| <p>Installing both <code>git</code> and <code>cmake</code> or <code>make</code> by following instructions on the websites is |
| straightforward. Here we provide the instructions to build <code>gcc-4.8</code> from source codes.</p> |
| |
| <p>Step 3. Install the 32-bit <code>libc</code> with one of the following system-specific commands:</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">sudo </span>apt-get <span class="nb">install </span>libc6-dev-i386 <span class="c"># In Ubuntu</span> |
| <span class="nb">sudo </span>yum <span class="nb">install </span>glibc-devel.i686 <span class="c"># In RHEL (Red Hat Linux)</span> |
| <span class="nb">sudo </span>yum <span class="nb">install </span>glibc-devel.i386 <span class="c"># In CentOS 5.8</span> |
| <span class="nb">sudo </span>yum <span class="nb">install </span>glibc-devel.i686 <span class="c"># In CentOS 6/7</span> |
| </code></pre></div> |
| <p>Step 4. Download and extract the <code>gcc</code> source code with the prerequisites:</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash">wget http://mirrors.concertpass.com/gcc/releases/gcc-4.8.5/gcc-4.8.5.tar.gz |
| <span class="nb">tar</span> <span class="nt">-zxf</span> gcc-4.8.5.tar.gz |
| <span class="nb">cd </span>gcc-4.8.5 |
| ./contrib/download_prerequisites |
| </code></pre></div> |
| <p>Step 5. Build <code>gcc</code> by using 10 threads and then install to <code>/usr/local</code></p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">mkdir </span>release <span class="o">&&</span> <span class="nb">cd </span>release |
| ../configure <span class="nt">--prefix</span><span class="o">=</span>/usr/local <span class="nt">--enable-languages</span><span class="o">=</span>c,c++ |
| make <span class="nt">-j10</span> |
| <span class="nb">sudo </span>make <span class="nb">install</span> |
| </code></pre></div> |
| <p>Step 6. Add the lib path to your configure file such as <code>~/.bashrc</code>:</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="k">${</span><span class="nv">LD_LIBRARY_PATH</span><span class="k">}</span>:/usr/local/lib64 |
| </code></pre></div> |
| <p>Step 7. Build <a href="https://github.com/xianyi/OpenBLAS#installation-from-source">OpenBLAS from source</a>.</p> |
| |
| <p>Step 8. Build OpenCV</p> |
| |
| <p>To build OpenCV from source code, you need the <a href="https://cmake.org">cmake</a> library.</p> |
| |
| <ul> |
| <li>If you don't have cmake or if your version of cmake is earlier than 3.6.1, run the following commands to install a newer version of cmake:</li> |
| </ul> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash">wget https://cmake.org/files/v3.6/cmake-3.6.1-Linux-x86_64.tar.gz |
| <span class="nb">tar</span> <span class="nt">-zxvf</span> cmake-3.6.1-Linux-x86_64.tar.gz |
| <span class="nb">alias </span><span class="nv">cmake</span><span class="o">=</span><span class="s2">"cmake-3.6.1-Linux-x86_64/bin/cmake"</span> |
| </code></pre></div> |
| <ul> |
| <li>To download and extract the OpenCV source code, run the following commands:</li> |
| </ul> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash">wget https://codeload.github.com/opencv/opencv/zip/2.4.13 |
| unzip 2.4.13 |
| <span class="nb">cd </span>opencv-2.4.13 |
| <span class="nb">mkdir </span>release |
| <span class="nb">cd </span>release/ |
| </code></pre></div> |
| <ul> |
| <li>Build OpenCV. The following commands build OpenCV with 10 threads. We |
| disabled GPU support, which might significantly slow down an MXNet program |
| running on a GPU processor. It also disables 1394 which might generate a |
| warning. Then install it on <code>/usr/local</code>.</li> |
| </ul> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash">cmake <span class="nt">-D</span> <span class="nv">BUILD_opencv_gpu</span><span class="o">=</span>OFF <span class="nt">-D</span> <span class="nv">WITH_CUDA</span><span class="o">=</span>OFF <span class="nt">-D</span> <span class="nv">WITH_1394</span><span class="o">=</span>OFF <span class="nt">-D</span> <span class="nv">CMAKE_BUILD_TYPE</span><span class="o">=</span>RELEASE <span class="nt">-D</span> <span class="nv">CMAKE_INSTALL_PREFIX</span><span class="o">=</span>/usr/local .. |
| make <span class="nt">-j10</span> |
| <span class="nb">sudo </span>make <span class="nb">install</span> |
| </code></pre></div> |
| <ul> |
| <li>Add the lib path to your configuration such as <code>~/.bashrc</code>.</li> |
| </ul> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">export </span><span class="nv">PKG_CONFIG_PATH</span><span class="o">=</span><span class="nv">$PKG_CONFIG_PATH</span>:/usr/local/lib/pkgconfig/ |

| <p>Apache MXNet is an effort undergoing incubation at The Apache Software Foundation (ASF), <span |

| or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF. |
