Grouping

W&B provides the ability to group runs up to two levels. This is useful for distributed training or combining multiple process types.

After you've run a run, our web interface lets you select any config variable and group runs that share the same value in that column.

If you'd like to specify grouping before you launch experiments, you have a couple options.

  1. ‚ÄčEnvironment Variable: Use theWANDB_RUN_GROUP environment variable

  2. Pass arguments to wandb.init:

    • For a single level of grouping, set the group argument

    • For a second level of grouping, set the job_type argument
