  • The new ModelRecommendation class can be used to retrieve the recommended models for a project.
  • A new helper method cross_validate was added to class Model. This method can be used to request Model’s Cross Validation score.
  • Training a model with monotonic constraints is now supported. Training with monotonic constraints allows users to force models to learn monotonic relationships with respect to some features and the target. This helps users create accurate models that comply with regulations (e.g. insurance, banking). Currently, only certain blueprints (e.g. xgboost) support this feature, and it is only supported for regression and binary classification projects.
  • DataRobot now supports “Database Connectivity”, allowing databases to be used as the source of data for projects and prediction datasets. The feature works on top of the JDBC standard, so a variety of databases conforming to that standard are available; a list of databases with tested support for DataRobot is available in the user guide in the web application. See Database Connectivity for details.
  • Added a new feature to retrieve feature logs for time series projects. Check datarobot.DatetimePartitioning.feature_log_list() and datarobot.DatetimePartitioning.feature_log_retrieve() for details.

API Changes

Deprecation Summary

Documentation Changes

  • “Advanced Model Insights” example has been updated to properly handle bin weights when rebinning.

2.9.0

New Features

  • New ModelDeployment class can be used to track status and health of models deployed for predictions.

Enhancements

  • DataRobot API now supports creating 3 new blender types - Random Forest, TensorFlow, LightGBM.
  • Multiclass projects now support blenders creation for 3 new blender types as well as Average and ENET blenders.
  • Models can be trained by requesting a particular row count using the new training_row_count argument with Project.train, Model.train and Model.request_frozen_model in non-datetime partitioned projects, as an alternative to the previous option of specifying a desired percentage of the project dataset. Specifying model size by row count is recommended when the float precision of sample_pct could be problematic, e.g. when training on a small percentage of the dataset or when training up to partition boundaries.
  • New attributes max_train_rows, scaleout_max_train_pct, and scaleout_max_train_rows have been added to Project. max_train_rows specified the equivalent value to the existing max_train_pct as a row count. The scaleout fields can be used to see how far scaleout models can be trained on projects, which for projects taking advantage of scalable ingest may exceed the limits on the data available to non-scaleout blueprints.
  • Individual features can now be marked as a priori or not a priori using the new feature_settings attribute when setting the target or specifying datetime partitioning settings on time series projects. Any features not specified in the feature_settings parameter will be assigned according to the default_to_a_priori value.
  • Three new options have been made available in the datarobot.DatetimePartitioningSpecification class to fine-tune how time-series projects derive modeling features. treat_as_exponential can control whether data is analyzed as an exponential trend and transformations like log-transform are applied. differencing_method can control which differencing method to use for stationary data. periodicities can be used to specify periodicities occuring within the data. All are optional and defaults will be chosen automatically if they are unspecified.

API Changes

  • Now training_row_count is available on non-datetime models as well as “rowCount” based datetime models. It reports the number of rows used to train the model (equivalent to sample_pct).
  • Features retrieved from Feature.get now include target_leakage.

2.8.1

Bugfixes

  • The documented default connect_timeout will now be correctly set for all configuration mechanisms, so that requests that fail to reach the DataRobot server in a reasonable amount of time will now error instead of hanging indefinitely. If you observe that you have started seeing ConnectTimeout errors, please configure your connect_timeout to a larger value.
  • Version of trafaret library this package depends on is now pinned to trafaret>=0.7,<1.1 since versions outside that range are known to be incompatible.

2.8.0

New Features

  • The DataRobot API supports the creation, training, and predicting of multiclass classification projects. DataRobot, by default, handles a dataset with a numeric target column as regression. If your data has a numeric cardinality of fewer than 11 classes, you can override this behavior to instead create a multiclass classification project from the data. To do so, use the set_target function, setting target_type=’Multiclass’. If DataRobot recognizes your data as categorical, and it has fewer than 11 classes, using multiclass will create a project that classifies which label the data belongs to.
  • The DataRobot API now includes Rating Tables. A rating table is an exportable csv representation of a model. Users can influence predictions by modifying them and creating a new model with the modified table. See the documentation for more information on how to use rating tables.
  • scaleout_modeling_mode has been added to the AdvancedOptions class used when setting a project target. It can be used to control whether scaleout models appear in the autopilot and/or available blueprints. Scaleout models are only supported in the Hadoop enviroment with the corresponding user permission set.
  • A new premium add-on product, Time Series, is now available. New projects can be created as time series projects which automatically derive features from past data and forecast the future. See the time series documentation for more information.
  • The Feature object now returns the EDA summary statistics (i.e., mean, median, minum, maximum, and standard deviation) for features where this is available (e.g., numeric, date, time, currency, and length features). These summary statistics will be formatted in the same format as the data it summarizes.
  • The DataRobot API now supports Training Predictions workflow. Training predictions are made by a model for a subset of data from original dataset. User can start a job which will make those predictions and retrieve them. See the documentation for more information on how to use training predictions.
  • DataRobot now supports retrieving a model blueprint chart and a model blueprint docs.
  • With the introduction of Multiclass Classification projects, DataRobot needed a better way to explain the performance of a multiclass model so we created a new Confusion Chart. The API now supports retrieving and interacting with confusion charts.

Enhancements

  • DatetimePartitioningSpecification now includes the optional disable_holdout flag that can be used to disable the holdout fold when creating a project with datetime partitioning.
  • When retrieving reason codes on a project using an exposure column, predictions that are adjusted for exposure can be retrieved.
  • File URIs can now be used as sourcedata when creating a project or uploading a prediction dataset. The file URI must refer to an allowed location on the server, which is configured as described in the user guide documentation.
  • The advanced options available when setting the target have been extended to include the new parameter ‘events_count’ as a part of the AdvancedOptions object to allow specifying the events count column. See the user guide documentation in the webapp for more information on events count.
  • PredictJob.get_predictions now returns predicted probability for each class in the dataframe.
  • PredictJob.get_predictions now accepts prefix parameter to prefix the classes name returned in the predictions dataframe.

API Changes

  • Add target_type parameter to set_target() and start(), used to override the project default.

2.7.2

Documentation Changes

  • Updated link to the publicly hosted documentation.

  • ROC curve data for models in classification projects can be retrieved using the Model.get_roc_curve and Model.get_all_roc_curves methods.
  • Semi-automatic autopilot mode is removed.
  • Word cloud data for text processing models can be retrieved using Model.get_word_cloud method.
  • Scoring code JAR file can be downloaded for models supporting code generation.

Enhancements

  • A __repr__ method has been added to the PredictionDataset class to improve readability when using the client interactively.
  • Model.get_parameters now includes an additional key in the derived features it includes, showing the coefficients for individual stages of multistage models (e.g. Frequency-Severity models).
  • When training a DatetimeModel on a window of data, a time_window_sample_pct can be specified to take a uniform random sample of the training data instead of using all data within the window.
  • Installing of DataRobot package now has an “Extra Requirements” section that will install all of the dependencies needed to run the example notebooks.

Documentation Changes

  • A new example notebook describing how to visualize some of the newly available model insights including lift charts, ROC curves, and word clouds has been added to the examples section.
  • A new section for Common Issues has been added to Getting Started to help debug issues related to client installation and usage.

2.6.1

Bugfixes

  • Fixed a bug with Model.get_parameters raising an exception on some valid parameter values.

Documentation Changes

  • Fixed sorting order in Feature Impact example code snippet.

2.6.0

New Features

  • A new partitioning method (datetime partitioning) has been added. The recommended workflow is to preview the partitioning by creating a DatetimePartitioningSpecification and passing it into DatetimePartitioning.generate, inspect the results and adjust as needed for the specific project dataset by adjusting the DatetimePartitioningSpecification and re-generating, and then set the target by passing the final DatetimePartitioningSpecification object to the partitioning_method parameter of Project.set_target.
  • When interacting with datetime partitioned projects, DatetimeModel can be used to access more information specific to models in datetime partitioned projects. See the documentation for more information on differences in the modeling workflow for datetime partitioned projects.
  • The advanced options available when setting the target have been extended to include the new parameters ‘offset’ and ‘exposure’ (part of the AdvancedOptions object) to allow specifying offset and exposure columns to apply to predictions generated by models within the project. See the user guide documentation in the webapp for more information on offset and exposure columns.
  • Blueprints can now be retrieved directly by project_id and blueprint_id via Blueprint.get.
  • Blueprint charts can now be retrieved directly by project_id and blueprint_id via BlueprintChart.get. If you already have an instance of Blueprint you can retrieve its chart using Blueprint.get_chart.
  • Model parameters can now be retrieved using ModelParameters.get. If you already have an instance of Model you can retrieve its parameters using Model.get_parameters.
  • Blueprint documentation can now be retrieved using Blueprint.get_documents. It will contain information about the task, its parameters and (when available) links and references to additional sources.
  • The DataRobot API now includes Reason Codes. You can now compute reason codes for prediction datasets. You are able to specify thresholds on which rows to compute reason codes for to speed up computation by skipping rows based on the predictions they generate. See the reason codes documentation for more information.

Enhancements

  • A new parameter has been added to the AdvancedOptions used with Project.set_target. By specifying accuracyOptimizedMb=True when creating AdvancedOptions, longer-running models that may have a high accuracy will be included in the autopilot and made available to run manually.
  • A new option for Project.create_type_transform_feature has been added which explicitly truncates data when casting numerical data as categorical data.
  • Added 2 new blenders for projects that use MAD or Weighted MAD as a metric. The MAE blender uses BFGS optimization to find linear weights for the blender that minimize mean absolute error (compared to the GLM blender, which finds linear weights that minimize RMSE), and the MAEL1 blender uses BFGS optimization to find linear weights that minimize MAE + a L1 penalty on the coefficients (compared to the ENET blender, which minimizes RMSE + a combination of the L1 and L2 penalty on the coefficients).

Bugfixes

  • Fixed a bug (affecting Python 2 only) with printing any model (including frozen and prime models) whose model_type is not ascii.
  • FrozenModels were unable to correctly use methods inherited from Model. This has been fixed.
  • When calling get_result for a Job, ModelJob, or PredictJob that has errored, AsyncProcessUnsuccessfulError will now be raised instead of JobNotFinished, consistently with the behaviour of get_result_when_complete.

Deprecation Summary

  • Support for the experimental Recommender Problems projects has been removed. Any code relying on RecommenderSettings or the recommender_settings argument of Project.set_target and Project.start will error.
  • Project.update, deprecated in v2.2.32, has been removed in favor of specific updates: rename, unlock_holdout, set_worker_count.

Documentation Changes

  • The link to Configuration from the Quickstart page has been fixed.

2.5.1

Bugfixes

  • Fixed a bug (affecting Python 2 only) with printing blueprints whose names are not ascii.
  • Fixed an issue where the weights column (for weighted projects) did not appear in the advanced_options of a Project.

2.5.0

New Features

  • Methods to work with blender models have been added. Use Project.blend method to create new blenders, Project.get_blenders to get the list of existing blenders and BlenderModel.get to retrieve a model with blender-specific information.
  • Projects created via the API can now use smart downsampling when setting the target by passing smart_downsampled and majority_downsampling_rate into the AdvancedOptions object used with Project.set_target. The smart sampling options used with an existing project will be available as part of Project.advanced_options.
  • Support for frozen models, which use tuning parameters from a parent model for more efficient training, has been added. Use Model.request_frozen_model to create a new frozen model, Project.get_frozen_models to get the list of existing frozen models and FrozenModel.get to retrieve a particular frozen model.

Enhancements

  • The inferred date format (e.g. “%Y-%m-%d %H:%M:%S”) is now included in the Feature object. For non-date features, it will be None.
  • When specifying the API endpoint in the configuration, the client will now behave correctly for endpoints with and without trailing slashes.

2.4.0

New Features

  • The premium add-on product DataRobot Prime has been added. You can now approximate a model on the leaderboard and download executable code for it. See documentation for further details, or talk to your account representative if the feature is not available on your account.
  • (Only relevant for on-premise users with a Standalone Scoring cluster.) Methods (request_transferable_export and download_export) have been added to the Model class for exporting models (which will only work if model export is turned on). There is a new class ImportedModel for managing imported models on a Standalone Scoring cluster.
  • It is now possible to create projects from a WebHDFS, PostgreSQL, Oracle or MySQL data source. For more information see the documentation for the relevant Project classmethods: create_from_hdfs, create_from_postgresql, create_from_oracle and create_from_mysql.
  • Job.wait_for_completion, which waits for a job to complete without returning anything, has been added.

Enhancements

  • The client will now check the API version offered by the server specified in configuration, and give a warning if the client version is newer than the server version. The DataRobot server is always backwards compatible with old clients, but new clients may have functionality that is not implemented on older server versions. This issue mainly affects users with on-premise deployments of DataRobot.

Bugfixes

  • Fixed an issue where Model.request_predictions might raise an error when predictions finished very quickly instead of returning the job.

API Changes

  • To set the target with quickrun autopilot, call Project.set_target with mode=AUTOPILOT_MODE.QUICK instead of specifying quickrun=True.

Deprecation Summary

  • Semi-automatic mode for autopilot has been deprecated and will be removed in 3.0. Use manual or fully automatic instead.
  • Use of the quickrun argument in Project.set_target has been deprecated and will be removed in 3.0. Use mode=AUTOPILOT_MODE.QUICK instead.

Configuration Changes

  • It is now possible to control the SSL certificate verification by setting the parameter ssl_verify in the config file.

Documentation Changes

  • The “Modeling Airline Delay” example notebook has been updated to work with the new 2.3 enhancements.
  • Documentation for the generic Job class has been added.
  • Class attributes are now documented in the API Reference section of the documentation.
  • The changelog now appears in the documentation.
  • There is a new section dedicated to configuration, which lists all of the configuration options and their meanings.

2.3.0

New Features

  • The DataRobot API now includes Feature Impact, an approach to measuring the relevance of each feature that can be applied to any model. The Model class now includes methods request_feature_impact (which creates and returns a feature impact job) and get_feature_impact (which can retrieve completed feature impact results).
  • A new improved workflow for predictions now supports first uploading a dataset via Project.upload_dataset, then requesting predictions via Model.request_predictions. This allows us to better support predictions on larger datasets and non-ascii files.
  • Datasets previously uploaded for predictions (represented by the PredictionDataset class) can be listed from Project.get_datasets and retrieve and deleted via PredictionDataset.get and PredictionDataset.delete.
  • You can now create a new feature by re-interpreting the type of an existing feature in a project by using the Project.create_type_transform_feature method.
  • The Job class now includes a get method for retrieving a job and a cancel method for canceling a job.
  • All of the jobs classes (Job, ModelJob, PredictJob) now include the following new methods: refresh (for refreshing the data in the job object), get_result (for getting the completed resource resulting from the job), and get_result_when_complete (which waits until the job is complete and returns the results, or times out).
  • A new method Project.refresh can be used to update Project objects with the latest state from the server.
  • A new function datarobot.async.wait_for_async_resolution can be used to poll for the resolution of any generic asynchronous operation on the server.

Enhancements

  • The JOB_TYPE enum now includes FEATURE_IMPACT.
  • The QUEUE_STATUS enum now includes ABORTED and COMPLETED.
  • The Project.create method now has a read_timeout parameter which can be used to keep open the connection to DataRobot while an uploaded file is being processed. For very large files this time can be substantial. Appropriately raising this value can help avoid timeouts when uploading large files.
  • The method Project.wait_for_autopilot has been enhanced to error if the project enters a state where autopilot may not finish. This avoids a situation that existed previously where users could wait indefinitely on their project that was not going to finish. However, users are still responsible to make sure a project has more than zero workers, and that the queue is not paused.
  • Feature.get now supports retrieving features by feature name. (For backwards compatibility, feature IDs are still supported until 3.0.)
  • File paths that have unicode directory names can now be used for creating projects and PredictJobs. The filename itself must still be ascii, but containing directory names can have other encodings.
  • Now raises more specific JobAlreadyRequested exception when we refuse a model fitting request as a duplicate. Users can explicitly catch this exception if they want it to be ignored.
  • A file_name attribute has been added to the Project class, identifying the file name associated with the original project dataset. Note that if the project was created from a data frame, the file name may not be helpful.
  • The connect timeout for establishing a connection to the server can now be set directly. This can be done in the yaml configuration of the client, or directly in the code. The default timeout has been lowered from 60 seconds to 6 seconds, which will make detecting a bad connection happen much quicker.

Bugfixes

  • Fixed a bug (affecting Python 2 only) with printing features and featurelists whose names are not ascii.

API Changes

  • Job class hierarchy is rearranged to better express the relationship between these objects. See documentation for datarobot.models.job for details.
  • Featurelist objects now have a project_id attribute to indicate which project they belong to. Directly accessing the project attribute of a Featurelist object is now deprecated
  • Support INI-style configuration, which was deprecated in v2.1, has been removed. yaml is the only supported configuration format.
  • The method Project.get_jobs method, which was deprecated in v2.1, has been removed. Users should use the Project.get_model_jobs method instead to get the list of model jobs.

Deprecation Summary

  • PredictJob.create has been deprecated in favor of the alternate workflow using Model.request_predictions.
  • Feature.converter (used internally for object construction) has been made private.
  • Model.fetch_resource_data has been deprecated and will be removed in 3.0. To fetch a model from
    its ID, use Model.get.
  • The ability to use Feature.get with feature IDs (rather than names) is deprecated and will be removed in 3.0.
  • Instantiating a Project, Model, Blueprint, Featurelist, or Feature instance from a dict of data is now deprecated. Please use the from_data classmethod of these classes instead. Additionally, instantiating a Model from a tuple or by using the keyword argument data is also deprecated.
  • Use of the attribute Featurelist.project is now deprecated. You can use the project_id attribute of a Featurelist to instantiate a Project instance using Project.get.
  • Use of the attributes Model.project, Model.blueprint, and Model.featurelist are all deprecated now to avoid use of partially instantiated objects. Please use the ids of these objects instead.
  • Using a Project instance as an argument in Featurelist.get is now deprecated. Please use a project_id instead. Similarly, using a Project instance in Model.get is also deprecated, and a project_id should be used in its place.

Configuration Changes

  • Previously it was possible (though unintended) that the client configuration could be mixed through environment variables, configuration files, and arguments to datarobot.Client. This logic is now simpler - please see the Getting Started section of the documentation for more information.

2.2.33

Bugfixes

  • Fixed a bug with non-ascii project names using the package with Python 2.
  • Fixed an error that occurred when printing projects that had been constructed from an ID only or printing printing models that had been constructed from a tuple (which impacted printing PredictJobs).
  • Fixed a bug with project creation from non-ascii file names. Project creation from non-ascii file names is not supported, so this now raises a more informative exception. The project name is no longer used as the file name in cases where we do not have a file name, which prevents non-ascii project names from causing problems in those circumstances.
  • Fixed a bug (affecting Python 2 only) with printing projects, features, and featurelists whose names are not ascii.

2.2.32

New Features

  • Project.get_features and Feature.get methods have been added for feature retrieval.
  • A generic Job entity has been added for use in retrieving the entire queue at once. Calling Project.get_all_jobs will retrieve all (appropriately filtered) jobs from the queue. Those can be cancelled directly as generic jobs, or transformed into instances of the specific job class using ModelJob.from_job and PredictJob.from_job, which allow all functionality previously available via the ModelJob and PredictJob interfaces.
  • Model.train now supports featurelist_id and scoring_type parameters, similar to Project.train.

Enhancements

  • Deprecation warning filters have been updated. By default, a filter will be added ensuring that usage of deprecated features will display a warning once per new usage location. In order to hide deprecation warnings, a filter like warnings.filterwarnings(‘ignore’, category=DataRobotDeprecationWarning) can be added to a script so no such warnings are shown. Watching for deprecation warnings to avoid reliance on deprecated features is recommended.
  • If your client is misconfigured and does not specify an endpoint, the cloud production server is no longer used as the default as in many cases this is not the correct default.
  • This changelog is now included in the distributable of the client.

Bugfixes

  • Fixed an issue where updating the global client would not affect existing objects with cached clients. Now the global client is used for every API call.
  • An issue where mistyping a filepath for use in a file upload has been resolved. Now an error will be raised if it looks like the raw string content for modeling or predictions is just one single line.

API Changes

  • Use of username and password to authenticate is no longer supported - use an API token instead.
  • Usage of start_time and finish_time parameters in Project.get_models is not supported both in filtering and ordering of models
  • Default value of sample_pct parameter of Model.train method is now None instead of 100. If the default value is used, models will be trained with all of the available training data based on project configuration, rather than with entire dataset including holdout for the previous default value of 100.
  • order_by parameter of Project.list which was deprecated in v2.0 has been removed.
  • recommendation_settings parameter of Project.start which was deprecated in v0.2 has been removed.
  • Project.status method which was deprecated in v0.2 has been removed.
  • Project.wait_for_aim_stage method which was deprecated in v0.2 has been removed.
  • Delay, ConstantDelay, NoDelay, ExponentialBackoffDelay, RetryManager classes from retry module which were deprecated in v2.1 were removed.
  • Package renamed to datarobot.

Deprecation Summary

  • Project.update deprecated in favor of specific updates: rename, unlock_holdout, set_worker_count.

Documentation Changes

  • A new use case involving financial data has been added to the examples directory.
  • Added documentation for the partition methods.

2.1.31

Bugfixes

  • In Python 2, using a unicode token to instantiate the client will now work correctly.

2.1.30

Bugfixes

  • The minimum required version of trafaret has been upgraded to 0.7.1 to get around an incompatibility between it and setuptools.

2.1.29

Enhancements

  • Minimal used version of requests_toolbelt package changed from 0.4 to 0.6

2.1.28

New Features

  • Default to reading YAML config file from ~/.config/datarobot/drconfig.yaml
  • Allow config_path argument to client
  • wait_for_autopilot method added to Project. This method can be used to block execution until autopilot has finished running on the project.
  • Support for specifying which featurelist to use with initial autopilot in Project.set_target
  • Project.get_predict_jobs method has been added, which looks up all prediction jobs for a project
  • Project.start_autopilot method has been added, which starts autopilot on specified featurelist
  • The schema for PredictJob in DataRobot API v2.1 now includes a message. This attribute has been added to the PredictJob class.
  • PredictJob.cancel now exists to cancel prediction jobs, mirroring ModelJob.cancel
  • Project.from_async is a new classmethod that can be used to wait for an async resolution in project creation. Most users will not need to know about it as it is used behind the scenes in Project.create and Project.set_target, but power users who may run into periodic connection errors will be able to catch the new ProjectAsyncFailureError and decide if they would like to resume waiting for async process to resolve

Enhancements

  • AUTOPILOT_MODE enum now uses string names for autopilot modes instead of numbers

Deprecation Summary

  • ConstantDelay, NoDelay, ExponentialBackoffDelay, and RetryManager utils are now deprecated
  • INI-style config files are now deprecated (in favor of YAML config files)
  • Several functions in the utils submodule are now deprecated (they are being moved elsewhere and are not considered part of the public interface)
  • Project.get_jobs has been renamed Project.get_model_jobs for clarity and deprecated
  • Support for the experimental date partitioning has been removed in DataRobot API, so it is being removed from the client immediately.

API Changes

  • In several places where AppPlatformError was being raised, now TypeError, ValueError or InputNotUnderstoodError are now used. With this change, one can now safely assume that when catching an AppPlatformError it is because of an unexpected response from the server.
  • AppPlatformError has gained a two new attributes, status_code which is the HTTP status code of the unexpected response from the server, and error_code which is a DataRobot-defined error code. error_code is not used by any routes in DataRobot API 2.1, but will be in the future. In cases where it is not provided, the instance of AppPlatformError will have the attribute error_code set to None.
  • Two new subclasses of AppPlatformError have been introduced, ClientError (for 400-level response status codes) and ServerError (for 500-level response status codes). These will make it easier to build automated tooling that can recover from periodic connection issues while polling.
  • If a ClientError or ServerError occurs during a call to Project.from_async, then a ProjectAsyncFailureError (a subclass of AsyncFailureError) will be raised. That exception will have the status_code of the unexpected response from the server, and the location that was being polled to wait for the asynchronous process to resolve.

2.0.27

New Features

  • PredictJob class was added to work with prediction jobs
  • wait_for_async_predictions function added to predict_job module
