SynapseML Development Setup

1. Install JDK 11
   • You may need an Oracle login to download.
2. Install SBT
3. Fork the repository on GitHub
   • See how to here: Fork a repo - GitHub Docs
4. Clone your fork
   • git clone https://github.com/<your GitHub handle>/SynapseML.git
   • This command will automatically add your fork as the default remote, called origin
5. Add another Git Remote to track the original SynapseML repo. It's recommended to call it upstream:
   • git remote add upstream https://github.com/microsoft/SynapseML.git
   • See more about Git remotes here: Git - Working with remotes
6. Go to the directory where you cloned the repo (for instance, SynapseML) with cd SynapseML
7. Run sbt to compile and grab datasets
   • sbt setup
8. Install IntelliJ
9. Configure IntelliJ
   • Install Scala plugin during initialization
   • OPEN the SynapseML directory from IntelliJ
   • If the project doesn't automatically import, click on build.sbt and import the project
10. Prepare your Python Environment
    • Install Miniconda
    • Note: if you want to run conda commands from IntelliJ, you may need to select the option to add conda to PATH during installation.
    • Activate the synapseml conda environment by running conda env create -f environment.yml from the synapseml directory. :::note If you're using a Windows machine, remove horovod requirement in the environment.yml file, because horovod installation only supports Linux or macOS. Horovod is used only for namespace synapse.ml.dl. :::
11. Update the ScalaTest Configuration Template
    • In IntelliJ, select the sandwich menu in the top left.
    • Select Run, then select Edit Configurations. At the bottom of the pop-up, select Edit Configuration Templates.
    • Select ScalaTest from the list on the right
    • Under VM options, add --add-exports java.base/sun.nio.ch=ALL-UNNAMED . Apply the changes.

NOTE

If you will be regularly contributing to the SynapseML repo, you'll want to keep your fork synced with the upstream repository. Please read this GitHub doc to know more and learn techniques about how to do it.
