The set of computation paths that a dataset passes through before producing predictions from data is called a blueprint. A blueprint can be trained on a dataset to generate a model.

To modify blueprints using python, please refer to the documentation for the Blueprint Workshop.

Quick Reference

The following code block summarizes the interactions available for blueprints.

# Get the set of blueprints recommended by datarobot
import datarobot as dr
my_projects = dr.Project.list()
project = my_projects[0]
menu = project.get_blueprints()

first_blueprint = menu[0]

List Blueprints

When a file is uploaded to a project and the target is set, DataRobot recommends a set of blueprints that are appropriate for the task at hand. You can use the get_blueprints method to get the list of blueprints recommended for a project:

project = dr.Project.get('5506fcd38bd88f5953219da0')
menu = project.get_blueprints()
blueprint = menu[0]

Get a blueprint

If you already have a blueprint_id from a model you can retrieve the blueprint directly.

project_id = '5506fcd38bd88f5953219da0'
project = dr.Project.get(project_id)
models = project.get_models()
model = models[0]
blueprint = Blueprint.get(project_id, model.blueprint_id)

Get a blueprint chart

For all blueprints - either from blueprint menu or already used in model - you can retrieve its chart. You can also get its representation in graphviz DOT format to render it into the format you need.

project_id = '5506fcd38bd88f5953219da0'
blueprint_id = '4321fcd38bd88f595321554223'
bp_chart = BlueprintChart.get(project_id, blueprint_id)

Get a blueprint’s documentation

You can retrieve documentation on tasks used in the blueprint. It will contain information about task, its parameters and (when available) links and references to additional sources. All documents are instances of BlueprintTaskDocument class.

project_id = '5506fcd38bd88f5953219da0'
blueprint_id = '4321fcd38bd88f595321554223'
bp = Blueprint.get(project_id, blueprint_id)
docs = bp.get_documents()
>>> Average Blend

Blueprint Attributes

The Blueprint class holds the data required to use the blueprint for modeling. This includes the blueprint_id and project_id. There are also two attributes that help distinguish blueprints: model_type and processes.

>>> u'8956e1aeecffa0fa6db2b84640fb3848'
>>> u5506fcd38bd88f5953219da0'
>>> Logistic Regression
>>> [u'One-Hot Encoding',
     u'Missing Values Imputed',
     u'Logistic Regression']

Create a Model from a Blueprint

You can use a blueprint instance to train a model. The default dataset for the project is used. Note that Project.train is used for non-datetime-partitioned projects. Project.train_datetime should be used for datetime partitioned projects.

model_job_id = project.train(blueprint)

# For datetime partitioned projects
model_job = project.train_datetime(

Both Project.train and Project.train_datetime will put a new modeling job into the queue. However, note that Project.train returns the id of the created ModelJob, while Project.train_datetime returns the ModelJob object itself. You can pass a ModelJob id to wait_for_async_model_creation function, which polls the async model creation status and returns the newly created model when it’s finished.
