| |
| <p>This tutorial guides you through setting up a Scala project in the IntelliJ IDE on macOS, and shows how to use the MXNet package from your application.</p> |
| |
| <h2 id="prerequisites">Prerequisites:</h2> |
| |
| <p>To use this tutorial you need the following software:</p> |
| |
| <ul> |
| <li><a href="https:///www.oracle.com/technetwork/java/javase/downloads/index.html">Java 8 JDK</a></li> |
| <li><a href="https://maven.apache.org/install.html">Maven</a></li> |
| <li><a href="https://www.scala-lang.org/download/">Scala</a> - comes with IntelliJ, so you don't need to install it separately</li> |
| <li><a href="https://opencv.org/">OpenCV</a></li> |
| <li><a href="https://www.jetbrains.com/idea/">IntelliJ IDE</a></li> |
| </ul> |
| |
| <p>The following instructions are provided for macOS and Ubuntu 16.04. Windows support is not yet available.</p> |
| |
| <h3 id="mac-prerequisites-setup">Mac Prerequisites Setup</h3> |
| |
| <p><strong>Step 1.</strong> Install brew: |
| <code> |
| /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" |
| </code></p> |
| |
| <p>Or, if you already have brew, update it: |
| <code> |
| brew update |
| </code></p> |
| |
| <p><strong>Step 2.</strong> Install Java 8 JDK: |
| <code> |
| brew tap caskroom/versions |
| brew cask install java8 |
| </code></p> |
| |
| <p><strong>Step 3.</strong> Install maven: |
| <code> |
| brew install maven |
| </code></p> |
| |
| <p><strong>Step 4.</strong> Install OpenCV: |
| <code> |
| brew install opencv |
| </code></p> |
| |
| <h3 id="ubuntu-prerequisites-setup">Ubuntu Prerequisites Setup</h3> |
| |
| <p><strong>Step 1.</strong>: Download the MXNet source.</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 |
| </code></pre></div> |
| <p><strong>Step 2.</strong>: Run the dependency installation scripts.</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">sudo</span> ./ci/docker/install/ubuntu_core.sh |
| <span class="nb">sudo</span> ./ci/docker/install/ubuntu_scala.sh |
| </code></pre></div> |
| <h2 id="access-the-maven-package-for-mxnet">Access the Maven Package for MXNet</h2> |
| |
| <p>To view the latest Maven packages, you can check the Maven repository for the <code>org.apache.mxnet</code> packages.</p> |
| |
| <ul> |
| <li> <a href="https://search.maven.org/#search%7Cga%7C1%7Cg%3A%22org.apache.mxnet%22">MXNet Maven Packages</a></li> |
| </ul> |
| |
| <p>In the tutorial below, you will install the latest package at the time of this writing. You may find a different artifact for your specific operating system, or a newer one by reviewing what is currently available in the Maven repo.</p> |
| |
| <p>The configuration you should update is in the pom file's dependency for MXNet:</p> |
| <div class="highlight"><pre><code class="language-html" data-lang="html"><span class="nt"><dependency></span> |
| <span class="nt"><groupId></span>org.apache.mxnet<span class="nt"></groupId></span> |
| <span class="nt"><artifactId></span>mxnet-full_2.11-osx-x86_64-cpu<span class="nt"></artifactId></span> |
| <span class="nt"></dependency></span> |
| </code></pre></div> |
| <h2 id="set-up-your-project">Set Up Your Project</h2> |
| |
| <p>Now that you've installed your prerequisites, you are ready to setup IntelliJ and your first MXNet-Scala project!</p> |
| |
| <p><strong>Step 1.</strong> Install and setup IntelliJ: |
| - When prompted for what to features to enable during IntelliJ's first startup, make sure you select Scala.</p> |
| <div class="highlight"><pre><code class="language-" data-lang="">- Install the plugin for IntelliJ IDE by following these steps: |
| </code></pre></div> |
| <p>On <strong>Menu</strong>, choose <strong>Preferences</strong>, choose <strong>Plugins</strong>, type <strong>Scala</strong>, and then choose <strong>Install</strong>. For further plugin help and instructions, refer to <a href="https://www.jetbrains.com/help/idea/scala.html">Scala plugin setup for IDE</a>.</p> |
| |
| <p><strong>Step 2.</strong> Create a new project:</p> |
| |

| 1.0-SNAPSHOT |
| </code></p> |
| |
| <p><img src="https://raw.githubusercontent.com/dmlc/web-data/master/mxnet/scala/intellij-project-properties.png" alt="project properties"></p> |
| |
| <p>Review the project's properties. The settings can be left as their default.</p> |
| |
| <p><img src="https://raw.githubusercontent.com/dmlc/web-data/master/mxnet/scala/intellij-project-location.png" alt="project location"></p> |
| |
| <p>Set the project's location. The rest of the settings can be left as their default.</p> |
| |
| <p><img src="https://raw.githubusercontent.com/dmlc/web-data/master/mxnet/scala/intellij-project-1.png" alt="project 1"></p> |
| |
| <p>After clicking Finish, you will be presented with the project's first view. |
| The project's <code>pom.xml</code> will be open for editing.</p> |
| |
| <p><strong>Step 3.</strong> Replace the pom file's content with the following code. Changes include: |
| - Project properties: <code>scala.version</code>, upgrading from <code>2.11.5</code> to <code>2.11.8</code> |

| <p>If you get an error, check the dependencies at the beginning of this tutorial. For example, you might see the following in the middle of the error messages, where <code>x.x</code> would the version it's looking for.</p> |
| <div class="highlight"><pre><code class="language-" data-lang="">... |
| Library not loaded: /usr/local/opt/opencv/lib/libopencv_calib3d.x.x.dylib |
| ... |
| </code></pre></div> |
| <p>This can be resolved be installing OpenCV.</p> |

| <h3 id="using-mxnet-from-source">Using MXNet from source</h3> |
| |
| <p>If you chose to "Build from Source" when following the <a href="/versions/1.9.1/get_started">install instructions</a> (or the detailed <a href="/versions/1.9.1/get_started/build_from_source.html#installing-mxnet-language-bindings">build from source instructions</a>), you can use your custom build instead of the build from maven. Use your build by editing the <code>pom.xml</code> file and replacing the <code>org.apache.mxnet</code> dependency with the following:</p> |
| <div class="highlight"><pre><code class="language-" data-lang=""> <groupId>org.apache.mxnet</groupId> |
| <artifactId>mxnet-core_${scala.version}-${platform}-sources</artifactId> |
| <scope>system</scope> |
| <systemPath>/PathToMXNetSource/mxnet/scala-package/assembly/osx-x86_64-cpu/target/mxnet-full_${scala.version}-osx-x86_64-cpu-1.9.1-SNAPSHOT-sources.jar</systemPath> |
| </dependency> |
| |
| <dependency> |
| <groupId>org.apache.mxnet</groupId> |
| <artifactId>mxnet-full_${scala.version}-${platform}</artifactId> |
| <scope>system</scope> |
| <systemPath>/PathToMXNetSource/mxnet/scala-package/assembly/osx-x86_64-cpu/target/mxnet-full_${scala.version}-osx-x86_64-cpu-1.9.1-SNAPSHOT.jar</systemPath> |
| </dependency> |
| </code></pre></div> |
| <p>Note that you have to edit both of the <code>systemPath</code> properties to point to your generated jar files.</p> |
| |
| <h3 id="command-line-build-option">Command Line Build Option</h3> |
| |
| <ul> |
| <li>You can also compile the project by using the following command at the command line. Change directories to this project's folder then run the following:</li> |
| </ul> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash">mvn clean package <span class="nt">-e</span> <span class="nt">-P</span> osx-x86_64-cpu |
| </code></pre></div> |
| <p>The <code>-P <platform></code> parameter tells the build which platform to target. |
| The <code>-e</code> will give you more details if the build fails. If it succeeds, you should see a lot of info and some warning messages, followed by:</p> |
| <div class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="o">[</span>INFO] <span class="nt">------------------------------------------------------------------------</span> |
| <span class="o">[</span>INFO] BUILD SUCCESS |
| <span class="o">[</span>INFO] <span class="nt">------------------------------------------------------------------------</span> |
| <span class="o">[</span>INFO] Total <span class="nb">time</span>: 1.186 s |
| <span class="o">[</span>INFO] Finished at: 2018-03-06T15:17:36-08:00 |
| <span class="o">[</span>INFO] Final Memory: 11M/155M |
| <span class="o">[</span>INFO] <span class="nt">------------------------------------------------------------------------</span> |
| </code></pre></div> |
| <p>The build generates a new jar file in the <code>target</code> folder called <code>scalaInference-1.0-SNAPSHOT.jar</code>.</p> |
