Accessing the summary file and evaluation manifest snapshot (SDK) - Rekognition

Accessing the summary file and evaluation manifest snapshot (SDK)

To get training results, you call DescribeProjectVersions. For example code, see Describing a model (SDK).

The location of the metrics is returned in the ProjectVersionDescription response from DescribeProjectVersions.

  • EvaluationResult – The location of the summary file.

  • TestingDataResult – The location of the evaluation manifest snapshot used for testing.

The F1 score and summary file location are returned in EvaluationResult. For example:

"EvaluationResult": {
                "F1Score": 1.0,
                "Summary": {
                    "S3Object": {
                        "Bucket": "echo-dot-scans",
                        "Name": "test-output/EvaluationResultSummary-my-echo-dots-project-v2.json"
                    }
                }
            }

The evaluation manifest snapshot is stored in the location specified in the --output-config input parameter that you specified in Training a model (SDK).

Note

The amount of time, in seconds, that you are billed for training is returned in BillableTrainingTimeInSeconds.
