Args: study: An optimized study. evaluator: An importance evaluator object that specifies which algorithm to base the importance assessment on. Defaults to :class:`~optuna.importance.FanovaImportanceEvaluator`. .. note:: Although the default importance evaluator in Optuna is :class:`~optuna.importance.FanovaImportanceEvaluator`, Optuna Dashboard uses a light-weight evaluator, i.e., :class:`~optuna.importance.PedAnovaImportanceEvaluator`, for runtime performance purposes, yielding a different result. params: A list of names of parameters to assess. If :obj:`None`, all parameters that are present in all of the completed trials are assessed. target: A function to specify the value to display. If it is :obj:`None` and ``study`` is being used for single-objective optimization, the objective values are plotted. For multi-objective optimization, all objectives will be plotted if ``target`` is :obj:`None`. .. note:: This argument can be used to specify which objective to plot if ``study`` is being used for multi-objective optimization. For example, to get only the hyperparameter importance of the first objective, use ``target=lambda t: t.values[0]`` for the target parameter. target_name: Target's name to display on the legend. Names set via :meth:`~optuna.study.Study.set_metric_names` will be used if ``target`` is :obj:`None`, overriding this argument. Returns: A :class:`plotly.graph_objects.Figure` object. )r checkrL_get_importances_plot)rrrr!rrIrrrplot_param_importancesqs6 rPinfosc Cshtjdddiddid}g}|D]}|jsq|tj|j|j|j|jddt||dd qt ||S) NzHyperparameter ImportancestitlezHyperparameter ImportanceHyperparameter)rRxaxisyaxisoutsideFh)xynametext textposition cliponaxis hovertemplate orientation) rLayoutrappendBarrrr_get_hover_templateFigure)rQrlayoutdatainforrrrOs, rO param_namercCs(|jD]}||jvr|j|SqJr?)r7 distributions)rhrtrialrrr_get_distributions  rkr/floatcCs$t||jj}|d|d|dS)Nz (z): z)rk __class__r)rhr/r class_namerrr_make_hovertextsroimportances_inforcsfddt|j|jDS)Ncsg|] \}}t||qSr)ro)r&rhr/rrrr(s z'_get_hover_template..)ziprr)rprrrqrrcs rc) rrrrrr r!r"rrr#r) rrrrrr r!r"rrr#r:)NN) rrrrrr r!r"rrr#rM)rQr:rrr#rM)rhrrrr#r)rhrr/rlrrr#r)rprrrr#r)# __future__rcollections.abcrtypingrr.optuna.distributionsroptuna.importance._baseroptuna.loggingr optuna.studyr optuna.trialr r $optuna.visualization._plotly_importsr optuna.visualization._utilsr r is_successfulrrr,rr9rLrPrOrkrorcrrrrs:              ', ;
