Build local training or execution runner

To build a local training or execution runner and execute from the command line, perform the following steps:

  1. Create an ML SDK project and add the following plugins to the Maven's pom.xml:

    <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>appassembler-maven-plugin</artifactId>
    <version>1.10</version>
    <configuration>
        <programs>
            <program>
                <name>runner</name>
                <mainClass>$MAIN_CLASS</mainClass>
                <!--<mainClass>com.wf.ml.run.ModelTrainingRunner</mainClass>-->
            </program>
        </programs>
        <assembleDirectory>runner</assembleDirectory>
        <repositoryName>lib</repositoryName>
        <repositoryLayout>flat</repositoryLayout>
    </configuration>
    <executions>
        <execution>
            <id>assembly</id>
            <phase>package</phase>
            <goals>
                <goal>assemble</goal>
            </goals>
        </execution>
    </executions>
</plugin>

<plugin>
    <artifactId>maven-clean-plugin</artifactId>
    <configuration>
        <filesets>
            <fileset>
                <directory>runner</directory>
            </fileset>
        </filesets>
    </configuration>
</plugin>

  2. To generate a runner script, run the execution command:

    mvn clean install
note
  • Replace $MAIN_CLASS with the path to your runner, for example: com.wf.ml.run.ModelTrainingRunner
  • By default, the runner directory is created in the base directory but it can be modified.
  • As a result, runner.bat and runner.sh are generated for Windows and UNIX based OS.
  • There is a clean plugin. You need to specify a runner directory to be deleted on the following compilation.
