nicetoolbox.evaluation.metrics.base_metric.MetricHandler

class nicetoolbox.evaluation.metrics.base_metric.MetricHandler(cfg: EvaluationMetricType, device: str)

Bases: ABC

Abstract base class for a metric handler (e.g., PointCloudMetric). A handler creates and manages one or more base Metric instances.

Initialize the metric handler with its config and device, creating its metrics.

Parameters:

• cfg (MetricTypeConfig) – Configuration for this metric type.

• device (str) – Device to run the metrics on (e.g., ‘cpu’ or ‘cuda’).

Methods

evaluate	Compute final results from all managed metrics.
process	Process a homogeneous, grouped batch of data for all managed metrics.

Attributes

name	The name of the metric handler (e.g., 'point_cloud_metrics').

evaluate() → Dict[Tuple[str, str, str], List[BatchResult] | AggregatedResult]

Compute final results from all managed metrics.

abstract property name: str

The name of the metric handler (e.g., ‘point_cloud_metrics’).

process(batch: Dict[str, Any]) → None

Process a homogeneous, grouped batch of data for all managed metrics.
