Return a non-200 HTTP response, or - Connection refused/timeout or - Response timeout or - Malformed request - Have a malformed/missing header in the response. ### exception datarobot.errors.ServerError For 500-level responses from the server ### exception datarobot.errors.ClientError For 400-level responses from the server has json parameter for additional information to be stored about error if need be ### exception datarobot.errors.InputNotUnderstoodError Raised if a method is called in a way that cannot be understood ### exception datarobot.errors.InvalidUsageError Raised when methods are called with invalid or incompatible arguments ### exception datarobot.errors.AllRetriesFailedError Raised when the retry manager does not successfully make a request ### exception datarobot.errors.InvalidModelCategoryError Raised when method specific for model category was called from wrong model ### exception datarobot.errors.AsyncTimeoutError Raised when an asynchronous operation did not successfully get resolved within a specified time limit ### exception datarobot.errors.AsyncFailureError Raised when querying an asynchronous status resulted in an exceptional status code (not 200 and not 303) ### exception datarobot.errors.ProjectAsyncFailureError When an AsyncFailureError occurs during project creation or finalizing the project settings for modeling. This exception will have the attributes `status_code` indicating the unexpected status code from the server, and `async_location` indicating which asynchronous status object was being polled when the failure happened. ### exception datarobot.errors.AsyncProcessUnsuccessfulError Raised when querying an asynchronous status showed that async process was not successful ### exception datarobot.errors.AsyncModelCreationError Raised when querying an asynchronous status showed that model creation was not successful ### exception datarobot.errors.AsyncPredictionsGenerationError Raised when querying an asynchronous status showed that predictions generation was not successful ### exception datarobot.errors.PendingJobFinished Raised when the server responds with a 303 for the pending creation of a resource. ### exception datarobot.errors.JobNotFinished Raised when execution was trying to get a finished resource from a pending job, but the job is not finished ### exception datarobot.errors.DuplicateFeaturesError Raised when trying to create featurelist with duplicating features ### exception datarobot.errors.TrainingDataAssignmentError Raised when the training data assignment for a custom model version fails ### exception datarobot.errors.DataRobotDeprecationWarning Raised when using deprecated functions or using functions in a deprecated way #### SEE ALSO [PlatformDeprecationWarning](https://docs.datarobot.com/en/docs/api/reference/sdk/errors.html#datarobot.errors.PlatformDeprecationWarning) ### exception datarobot.errors.IllegalFileName Raised when trying to use a filename we can’t handle. ### exception datarobot.errors.JobAlreadyRequested Raised when the requested model has already been requested. ### exception datarobot.errors.ContentRetrievalTerminatedError Raised when due to content retrieval error process of data retrieval was terminated. ### exception datarobot.errors.CredentialsError Raised for errors related to credentials. ### exception datarobot.errors.UpdateAttributesError ### exception datarobot.errors.InvalidRatingTableWarning Raised when using interacting with rating tables that failed validation ### exception datarobot.errors.PartitioningMethodWarning Raised when interacting with project methods related to partition classes, i.e. Project.set_partitioning_method() or Project.set_datetime_partitioning(). ### exception datarobot.errors.NonPersistableProjectOptionWarning Raised when setting project options via Project.set_options if any of the options passed are not supported for POST requests to /api/v2/project/{project_id}/options/. All options that fall under this category can be found here: `datarobot.enums.NonPersistableProjectOptions()`. ### exception datarobot.errors.OverwritingProjectOptionWarning Raised when setting project options via Project.set_options if any of the options passed have already been set to a value in Project.advanced_options, or if a different value is already stored in the endpoint /api/v2/project/{project_id}/options/. Precedence is given to the new value you passed in. ### exception datarobot.errors.NoRedundancyImpactAvailable Raised when retrieving old feature impact data Redundancy detection was added in v2.13 of the API, and some projects, e.g., multiclass projects do not support redundancy detection. This warning is raised to make clear that redundancy detection is unavailable. ### exception datarobot.errors.ParentModelInsightFallbackWarning Raised when insights are unavailable for a model and insight retrieval falls back to retrieving insights for a model’s parent model ### exception datarobot.errors.ProjectHasNoRecommendedModelWarning Raised when a project has no recommended model. ### exception datarobot.errors.PlatformDeprecationWarning Raised when Deprecation header is returned in the API, for example a project may be deprecated as part of the 2022 Python 3 platform migration. #### SEE ALSO [DataRobotDeprecationWarning](https://docs.datarobot.com/en/docs/api/reference/sdk/errors.html#datarobot.errors.DataRobotDeprecationWarning) ### exception datarobot.errors.MultipleUseCasesNotAllowed Raised when a method decorated with add_to_use_case(allow_multiple=True) calls a method decorated with add_to_use_case(allow_multiple=False) with multiple UseCases passed
