Prerequisites:¶

To use this tutorial, you need:

• Maven 3.
• Scala 2.11.8.
• MXNet. See the instructions for your operating system in Setup and Installation.
• The MXNet package for Scala. For installation instructions, see this procedure.
• IntelliJ IDE.

Set Up Your Project¶

• Install the plugin for IntelliJ IDE by following these steps: On Menu, choose Preferences, choose Plugins, type Scala, and then choose Install.
• Follow the instructions for Scala plugin setup for IDE.
• When you build the MXNet package with Scala, a JAR file called mxnet-full_${scala.binary.version}-${platform} is generated in native//target directory. You need this file to create an example package that has a dependency on MXNet.
• Specify project dependencies in pom.xml:

    <dependencies>
      <dependency>
        <groupId>ml.dmlc.mxnetgroupId>
        <artifactId>mxnet-full_${scala.binary.version}-${platform}artifactId>
        <version>0.1.1version>
        <scope>systemscope>
        <systemPath>`MXNet-Scala-jar-path`systemPath>
      dependency>
      <dependency>
        <groupId>args4jgroupId>
        <artifactId>args4jartifactId>
        <version>2.0.29version>
      dependency>
    dependencies>

Be sure to change the system path of MXNet-Scala-jar, which is in the native//target directory.

• Choose the example project, choose Maven, and then reimport. These steps add all of the dependencies in pom.xml as external libraries in your project.
• To build the project, choose Menu, choose Build, and then choose Rebuild Project. If errors are reported in the IDE, address them.
• You can also compile the project by using the following command at the command line.

    cd mxnet-scala-example
    mvn clean package

• This also generates a file called mxnet-scala-example-0.1-SNAPSHOT.jar for your application.
