MachineLearning.Client.describe_batch_predictions(**kwargs)#

Returns a list of BatchPrediction operations that match the search criteria in the request.

Request Syntax

response = client.describe_batch_predictions(
    FilterVariable='CreatedAt'|'LastUpdatedAt'|'Status'|'Name'|'IAMUser'|'MLModelId'|'DataSourceId'|'DataURI',
    EQ='string',
    GT='string',
    LT='string',
    GE='string',
    LE='string',
    NE='string',
    Prefix='string',
    SortOrder='asc'|'dsc',
    NextToken='string',
    Limit=123
)

Parameters:

FilterVariable (string) –
Use one of the following variables to filter a list of BatchPrediction:
- CreatedAt - Sets the search criteria to the BatchPrediction creation date.
- Status - Sets the search criteria to the BatchPrediction status.
- Name - Sets the search criteria to the contents of the BatchPrediction Name.
- IAMUser - Sets the search criteria to the user account that invoked the BatchPrediction creation.
- MLModelId - Sets the search criteria to the MLModel used in the BatchPrediction.
- DataSourceId - Sets the search criteria to the DataSource used in the BatchPrediction.
- DataURI - Sets the search criteria to the data file(s) used in the BatchPrediction. The URL can identify either a file or an Amazon Simple Storage Solution (Amazon S3) bucket or directory.
EQ (string) – The equal to operator. The BatchPrediction results will have FilterVariable values that exactly match the value specified with EQ.
GT (string) – The greater than operator. The BatchPrediction results will have FilterVariable values that are greater than the value specified with GT.
LT (string) – The less than operator. The BatchPrediction results will have FilterVariable values that are less than the value specified with LT.
GE (string) – The greater than or equal to operator. The BatchPrediction results will have FilterVariable values that are greater than or equal to the value specified with GE.
LE (string) – The less than or equal to operator. The BatchPrediction results will have FilterVariable values that are less than or equal to the value specified with LE.
NE (string) – The not equal to operator. The BatchPrediction results will have FilterVariable values not equal to the value specified with NE.
Prefix (string) –
A string that is found at the beginning of a variable, such as Name or Id.

For example, a Batch Prediction operation could have the Name 2014-09-09-HolidayGiftMailer. To search for this BatchPrediction, select Name for the FilterVariable and any of the following strings for the Prefix:
- 2014-09
- 2014-09-09
- 2014-09-09-Holiday
SortOrder (string) –
A two-value parameter that determines the sequence of the resulting list of ``MLModel``s.
- asc - Arranges the list in ascending order (A-Z, 0-9).
- dsc - Arranges the list in descending order (Z-A, 9-0).
Results are sorted by FilterVariable.
NextToken (string) – An ID of the page in the paginated results.
Limit (integer) – The number of pages of information to include in the result. The range of acceptable values is 1 through 100. The default value is 100.

Return type:

dict

Response Structure

(dict) –

Represents the output of a DescribeBatchPredictions operation. The content is essentially a list of ``BatchPrediction``s.
- Results (list) –
  
  A list of BatchPrediction objects that meet the search criteria.
  - (dict) –
    
    Represents the output of a GetBatchPrediction operation.
    
    The content consists of the detailed metadata, the status, and the data file information of a Batch Prediction.
    - BatchPredictionId (string) –
      
      The ID assigned to the BatchPrediction at creation. This value should be identical to the value of the BatchPredictionID in the request.
    - MLModelId (string) –
