nannyml.performance_calculation.result module¶
Contains the results of the realized performance calculation and provides plotting functionality.
- class nannyml.performance_calculation.result.Result(results_data: pandas.core.frame.DataFrame, problem_type: nannyml._typing.ProblemType, y_pred: str, y_pred_proba: Optional[Union[str, Dict[str, str]]], y_true: str, metrics: List[nannyml.performance_calculation.metrics.base.Metric], timestamp_column_name: Optional[str] = None, reference_data: Optional[pandas.core.frame.DataFrame] = None, analysis_data: Optional[pandas.core.frame.DataFrame] = None)[source]¶
Bases:
nannyml.base.Abstract1DResult
,nannyml.plots.blueprints.comparisons.ResultCompareMixin
Contains the results of the realized performance calculation and provides plotting functionality.
Creates a new Result instance.
- plot(kind: str = 'performance', *args, **kwargs) Optional[plotly.graph_objs._figure.Figure] [source]¶
Render realized performance metrics.
The following kinds of plots are available:
performance
a step plot showing the realized performance metric per
Chunk
for a given metric.
- Parameters
kind (str, default='performance') – The kind of plot to render. Only the ‘performance’ plot is currently available.
- Returns
fig – A
Figure
object containing the requested drift plot.Can be saved to disk using the
write_image()
method or shown rendered on screen using theshow()
method.- Return type
plotly.graph_objs._figure.Figure
