Suite for evaluating the model’s performance over different metrics, segments, error analysis, comparing to baseline, and more.
- List of Checks:
# Check Example
API Reference
- Parameters
- alternative_metricsDict[str, Metric], default: None
A dictionary of metrics, where the key is the metric name and the value is an ignite.Metric object whose score should be used. If None are given, use the default metrics.
- area_range: tuple, default: (32**2, 96**2)
Slices for small/medium/large buckets. (For object detection tasks only)
- image_propertiesList[Dict[str, Any]], default: None
List of properties. Replaces the default deepchecks properties. Each property is a dictionary with keys
'name'
(str),method
(Callable) and'output_type'
(str), representing attributes of said method. ‘output_type’ must be one of:'numeric'
- for continuous ordinal outputs.'categorical'
- for discrete, non-ordinal outputs. These can still be numbers, but these numbers do not have inherent value.
For more on image / label properties, see the guide about Data Properties.
- prediction_propertiesList[Dict[str, Any]], default: None
List of properties. Replaces the default deepchecks properties. Each property is a dictionary with keys
'name'
(str),method
(Callable) and'output_type'
(str), representing attributes of said method. ‘output_type’ must be one of:'numeric'
- for continuous ordinal outputs.'categorical'
- for discrete, non-ordinal outputs. These can still be numbers, but these numbers do not have inherent value.'class_id'
- for properties that return the class_id. This is used because these properties are later matched with theVisionData.label_map
, if one was given.
For more on image / label properties, see the guide about Data Properties.
- random_stateint, default: 42
random seed for all checks.
- **kwargsdict
additional arguments to pass to the checks.
- Returns
- Suite
A suite for evaluating the model’s performance.

- Parameters
- train_dataset: Optional[VisionData] , default None
object, representing data an estimator was fitted on

- scorersOptional[Mapping[str, Metric]] , default: None
dict of scorers names to a Metric

Dictionary of the model prediction over the test dataset (keys are the indexes).
- run_single_dataset: Optional[str], default None
‘Train’, ‘Test’ , or None to run on both train and test.
