| |
| <p>The following instructions are provided for macOS and Ubuntu. Windows is not yet available.</p> |
| |
| <p><strong>Note:</strong> If you use IntelliJ or a similar IDE, you may want to follow the <a href="/versions/1.9.1/api/java/docs/tutorials/mxnet_java_on_intellij">MXNet-Java on IntelliJ tutorial</a> instead of these instructions.</p> |
| |
| <p><hr></p> |
| |
| <h2 id="maven">Maven</h2> |
| |
| <h3 id="setup-instructions">Setup Instructions</h3> |
| |
| <p><strong>Step 1.</strong> Install dependencies:</p> |
| |
| <p><strong>macOS Steps</strong></p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash">brew update |
| brew tap caskroom/versions |
| brew cask <span class="nb">install </span>java8 |
| brew <span class="nb">install </span>maven |
| </code></pre></div> |
| <p><strong>Ubuntu Steps</strong></p> |
| |
| <p>Please run the following lines:</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">sudo </span>apt-get <span class="nb">install </span>openjdk-8-jdk maven |
| </code></pre></div> |
| <p><strong>Step 2.</strong> Run the demo MXNet-Java project.</p> |
| |
| <p>Go to the <a href="https://github.com/apache/mxnet/tree/master/scala-package/mxnet-demo/java-demo">MXNet-Java demo project's README</a> and follow the directions to test the MXNet-Java package installation.</p> |
| |
| <h4 id="maven-repository">Maven Repository</h4> |
| |
| <p>MXNet-Java can be easily included in your Maven managed project. The Java packages are currently available on Maven. Add the dependency which corresponds to your platform to the <code>dependencies</code> tag :</p> |
| |
| <p><strong>Linux CPU</strong> |
| <code>html |
| <dependency> |
| <groupId>org.apache.mxnet</groupId> |
| <artifactId>mxnet-full_2.11-linux-x86_64-cpu</artifactId> |
| <version>1.4.0</version> |
| </dependency> |
| </code></p> |
| |
| <p><strong>Linux GPU</strong> |
| <code>html |
| <dependency> |
| <groupId>org.apache.mxnet</groupId> |
| <artifactId>mxnet-full_2.11-linux-x86_64-gpu</artifactId> |

| |
| <p><strong>macOS CPU</strong> |
| <code>html |

| <artifactId>mxnet-full_2.11-osx-x86_64-cpu</artifactId> |
| <version>1.4.0</version> |
| </dependency> |
| </code></p> |
| |
| <p>The official Java Packages have been released as part of MXNet 1.4 and are available on the <a href="https://search.maven.org/#search%7Cga%7C1%7Cg%3A%22org.apache.mxnet%22">MXNet Maven package repository</a>. |
| <hr></p> |
| |
| <h3 id="eclipse-ide-support">Eclipse IDE Support</h3> |
| |
| <p>You can convert your existing Maven project to a project that can run in Eclipse by: |
| <code> |
| mvn eclipse:eclipse |
| </code> |
| This can be done once you have your maven project properly configured.</p> |
| |
| <h2 id="source">Source</h2> |
| |
| <p>The previously mentioned setup with Maven is recommended. Otherwise, the following instructions for macOS and Ubuntu are provided for reference only:</p> |
| |
| <p><strong>If you have already built mxnet from source using <code>cmake</code>, run <code>make clean</code> and then follow the appropriate guide below</strong>*</p> |

| |
| <p>If you have already built MXNet <strong>from source</strong> and are looking to setup Java from that point, you may simply run the following from the MXNet <code>scala-package</code> folder:</p> |
| <div class="highlight"><pre><code class="language-" data-lang="">mvn install |
| </code></pre></div> |
| <p>This will install both the Java Inference API and the required MXNet-Scala package. |

| |
| <p>Javadocs are generated as part of the docs build pipeline. You can find them published in the <a href="/versions/1.9.1/api/java">Java API</a> section of the website or by going to the <a href="/versions/1.9.1/api/scala/docs/api/#org.apache.mxnet.package">scaladocs output</a> directly.</p> |
