Auger.ai API

Base Classes

auger.api.Context

Context provides environment to run Auger Experiments and Models:

  • loads Auger Credentials and initializes Auger REST API to communicate with remote Auger Cloud;
  • loads Auger settings from auger.yaml and provides access to these settings to Auger classes and business objects;
  • provides logging interface to all Auger classes and business objects.

Credentials could be acquired using Auger CLI auth command or loaded from Auger website. Credentials lookup and loading order:

  • form environment variable AUGER_CREDENTIALS set with content of the credentials json;
  • from auger.json file, path to folder with credentials set with environment variable AUGER_CREDENTIALS_PATH;
  • from auger.json file, path to folder with credentials set with path_to_credentials key in auger.yaml
  • if none above, form $HOME/.augerai/auger.json

auger.api.Project

Project provides interface to Auger Project.

  • Project(context, project_name) - constructs Project instance.

    • context - instance of auger.api.Context.
    • project_name - name of the existing or new Project, optional.
  • list() - lists all Projects in your Organization. Returns iterator where each item is dictionary with Project properties. Throws exception if can't validate credentials or network connection error.

    Example:

    ctx = Context()
    for project in iter(Project(ctx).list()):
      ctx.log(project.get('name'))
    
  • create() - creates Project on Auger Cloud. Throws exception if can't validate credentials, Project with such name already exists, or network connection error.

    Example:

    ctx = Context()
    project = Project(ctx, new_project_name).create()
    
  • delete() - deletes Project on Auger Cloud. Throws exception if can't validate credentials, Project with such name doesn't exist, or network connection error.

    Example:

    ctx = Context()
    Project(ctx, existing_project_name).delete()
    
  • start() - starts Project cluster. DataSet processing, Experiment runs and Model deploy and predict need cluster to perform operations and will start cluster automatically. It is possible, but not necessary, to start cluster beforehand. Throws exception if can't validate credentials or network connection error.

    Project cluster configuration defined in auger.yaml:

    cluster:
      # Cluster node type: standard|high_memory
      type: high_memory
      # Minimal number of cluster nodes
      min_nodes: 2
      # Maximum number of cluster nodes
      max_nodes: 4
      # Cluster software stack version - optional
      stack_version: experimental
    

    Example:

    ctx = Context()
    Project(ctx, project_name).start()
    
  • stop() - stops Project cluster. DataSet processing, Experiment runs and Model deploy and predict need cluster to perform operations and will start cluster automatically. Cluster will stop automatically after some inactivity period. To stop it explicitly, use Project stop() method. Throws exception if can't validate credentials, such project doesn't exist, or network connection error.

    Example:

    ctx = Context()
    Project(ctx, project_name).stop()
    
  • properties() - returns dictionary with Project properties. Throws exception if can't validate credentials, such Project doesn't exist, or network connection error.

    Example:

    ctx = Context()
    properties = Project(ctx, project_name).properties()
    

auger.api.DataSet

DataSet for training on Auger Cloud.

  • DataSet(context, project, dataset_name) - constructs DataSet instance.

    • context - instance of auger.api.Context.
    • project - instance of auger.api.Project pointing to existing remote project.
    • dataset_name - name of the existing or new DataSet, optional.
  • list() - lists all DataSets(s) for the Project. Returns iterator where each item is dictionary with DataSet properties. Throws exception if can't validate credentials, parent project doesn't exist, or network connection error.

    Example:

    ctx = Context()
    project = Project(ctx, project_name)
    for dataset in iter(DataSet(ctx, project).list()):
      ctx.log(dataset.get('name'))
    
  • create(source) - creates new DataSet on Auger Cloud from the local or remote data file. If dataset_name is not set, name will be selected automatically. Throws exception if can't validate credentials, parent project doesn't exist, DataSet with specified name already exists, or network connection error.

    • source - path to local or link to remote .csv or .arff file

    If Project cluster is not running, it will be started automatically to parse and preprocess DataSet.

    Example:

    ctx = Context()
    project = Project(ctx, project_name)
    dataset = DataSet(ctx, project).create('../iris.csv')
    ctx.log('Created dataset %s' % dataset.name)
    
  • delete() - deletes DataSet on Auger Cloud. Throws exception if can't validate credentials, parent project doesn't exist, DataSet with specified name doesn't exist, or network connection error.

    Example:

    ctx = Context()
    project = Project(ctx, project_name)
    DataSet(ctx, project, dataset_name).delete()
    ctx.log('Deleted dataset %s' % dataset_name)
    
  • properties() - returns dictionary with DataSet properties. Throws exception if can't validate credentials, such DataSet doesn't exist, or network connection error.

    Example:

    ctx = Context()
    project = Project(ctx, project_name)
    properties = DataSet(ctx, project, dataset_name).properties()
    

auger.api.Experiment

    • experiment_name - name of the existing or new Experiment, optional.
  • list() - list all Experiment(s) for the DataSet. Returns iterator where each item is dictionary with Experiment properties. Throws exception if can't validate credentials, parent DataSet doesn't exist, or network connection error.

    Example:

    ctx = Context()
    project = Project(ctx, project_name)
    dataset = DataSet(ctx, project, dataset_name)
    for exp in iter(Experiment(ctx, dataset).list()):
      ctx.log(exp.get('name'))
    
  • start() - starts Experiment with selected DataSet; Experiment settings configured in auger.yaml. If experiment_name is not set in constructor, unique name for the Experiment will be created automatically. Throws exception if can't validate credentials, parent DataSet doesn't exist, experiment with such name already exists, or network connection error.

    If Project cluster is not running, it will be started automatically to process search for the best Model.

    Example:

    else:
        ctx.log('Search is not running. Stop is ignored.')
    
  • leaderboard(run_id) - leaderboard of the currently running or previously completed experiment(s).
