| <ol class="simple"> |
| <li>Download the latest prebuilt package from the <a class="reference external" href="https://github.com/dmlc/mxnet/releases">Releases</a> tab of MXNet.</li> |
| <li>Unpack the package into a folder, with an appropriate name, such as <code class="docutils literal"><span class="pre">D:\MXNet</span></code>.</li> |
| <li>Open the folder, and install the package by double-clicking <code class="docutils literal"><span class="pre">setupenv.cmd</span></code>. This sets up all of the environment variables required by MXNet.</li> |
| <li>Test the installation by opening the provided sample C++ Visual Studio solution and building it.</li> |

| <p>The MXNet package for Julia is hosted in a separate repository, MXNet.jl, which is available on <a class="reference external" href="https://github.com/dmlc/MXNet.jl">GitHub</a>. To use Julia binding it with an existing libmxnet installation, set the <code class="docutils literal"><span class="pre">MXNET_HOME</span></code> environment variable by running the following command:</p> |

| <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> |

| <p>For Linux and OS X (Mac) 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> |

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