SCREAMING_SNAKE_CASE:    Optional[int]											=   '''
This metric computes the area under the curve (AUC) for the Receiver Operating Characteristic Curve (ROC). The return values represent how well the model used is predicting the correct classes, based on the input data. A score of `0.5` means that the model is predicting exactly at chance, i.e. the model\'s predictions are correct at the same rate as if the predictions were being decided by the flip of a fair coin or the roll of a fair die. A score above `0.5` indicates that the model is doing better than chance, while a score below `0.5` indicates that the model is doing worse than chance.

This metric has three separate use cases:
    - binary: The case in which there are only two different label classes, and each example gets only one label. This is the default implementation.
    - multiclass: The case in which there can be more than two different label classes, but each example still gets only one label.
    - multilabel: The case in which there can be more than two different label classes, and each example can have more than one label.

SCREAMING_SNAKE_CASE:    List[Any]											=   '''
Args:
- references (array-like of shape (n_samples,) or (n_samples, n_classes)): Ground truth labels. Expects different input based on use case:
    - binary: expects an array-like of shape (n_samples,)
    - multiclass: expects an array-like of shape (n_samples,)
    - multilabel: expects an array-like of shape (n_samples, n_classes)
- prediction_scores (array-like of shape (n_samples,) or (n_samples, n_classes)): Model predictions. Expects different inputs based on use case:
    - binary: expects an array-like of shape (n_samples,)
    - multiclass: expects an array-like of shape (n_samples, n_classes)
    - multilabel: expects an array-like of shape (n_samples, n_classes)
- average (`str`): Type of average, and is ignored in the binary use case. Defaults to \'macro\'. Options are:
    - `\'micro\'`: Calculates metrics globally by considering each element of the label indicator matrix as a label. Only works with the multilabel use case.
    - `\'macro\'`: Calculate metrics for each label, and find their unweighted mean.  This does not take label imbalance into account.
    - `\'weighted\'`: Calculate metrics for each label, and find their average, weighted by support (i.e. the number of true instances for each label).
    - `\'samples\'`: Calculate metrics for each instance, and find their average. Only works with the multilabel use case.
    - `None`:  No average is calculated, and scores for each class are returned. Only works with the multilabels use case.
- sample_weight (array-like of shape (n_samples,)): Sample weights. Defaults to None.
- max_fpr (`float`): If not None, the standardized partial AUC over the range [0, `max_fpr`] is returned. Must be greater than `0` and less than or equal to `1`. Defaults to `None`. Note: For the multiclass use case, `max_fpr` should be either `None` or `1.0` as ROC AUC partial computation is not currently supported for `multiclass`.
- multi_class (`str`): Only used for multiclass targets, where it is required. Determines the type of configuration to use. Options are:
    - `\'ovr\'`: Stands for One-vs-rest. Computes the AUC of each class against the rest. This treats the multiclass case in the same way as the multilabel case. Sensitive to class imbalance even when `average == \'macro\'`, because class imbalance affects the composition of each of the \'rest\' groupings.
    - `\'ovo\'`: Stands for One-vs-one. Computes the average AUC of all possible pairwise combinations of classes. Insensitive to class imbalance when `average == \'macro\'`.
- labels (array-like of shape (n_classes,)): Only used for multiclass targets. List of labels that index the classes in
    `prediction_scores`. If `None`, the numerical or lexicographical order of the labels in
    `prediction_scores` is used. Defaults to `None`.
Returns:
    roc_auc (`float` or array-like of shape (n_classes,)): Returns array if in multilabel use case and `average=\'None\'`. Otherwise, returns `float`.
Examples:
    Example 1:
        >>> roc_auc_score = datasets.load_metric("roc_auc")
        >>> refs = [1, 0, 1, 1, 0, 0]
        >>> pred_scores = [0.5, 0.2, 0.99, 0.3, 0.1, 0.7]
        >>> results = roc_auc_score.compute(references=refs, prediction_scores=pred_scores)
        >>> print(round(results[\'roc_auc\'], 2))
        0.78

    Example 2:
        >>> roc_auc_score = datasets.load_metric("roc_auc", "multiclass")
        >>> refs = [1, 0, 1, 2, 2, 0]
        >>> pred_scores = [[0.3, 0.5, 0.2],
        ...                 [0.7, 0.2, 0.1],
        ...                 [0.005, 0.99, 0.005],

        ...                 [0.1, 0.7, 0.2]]
        >>> results = roc_auc_score.compute(references=refs, prediction_scores=pred_scores, multi_class=\'ovr\')
        >>> print(round(results[\'roc_auc\'], 2))
        0.85

        >>> roc_auc_score = datasets.load_metric("roc_auc", "multilabel")
        >>> refs = [[1, 1, 0],
        ...         [1, 1, 0],

								    ' The Palestinians signed the ICC\'s founding Rome Statute in January, when they also accepted its'
								    ' jurisdiction over alleged crimes committed "in the occupied Palestinian territory, including East'
								    ' Jerusalem, since June 13, 2014." Later that month, the ICC opened a preliminary examination into the'
								    ' situation in Palestinian territories, paving the way for possible war crimes investigations against'
								    ' Israelis. As members of the court, Palestinians may be subject to counter-charges as well. Israel and'
								    ' the United States, neither of which is an ICC member, opposed the Palestinians\' efforts to join the'
								    ' body. But Palestinian Foreign Minister Riad al-Malki, speaking at Wednesday\'s ceremony, said it was a'
								    ' move toward greater justice. "As Palestine formally becomes a State Party to the Rome Statute today, the'
								    ' world is also a step closer to ending a long era of impunity and injustice," he said, according to an'
								    ' ICC news release. "Indeed, today brings us closer to our shared goals of justice and peace." Judge'
								    ' Kuniko Ozaki, a vice president of the ICC, said acceding to the treaty was just the first step for the'
								    ' Palestinians. "As the Rome Statute today enters into force for the State of Palestine, Palestine'
								    ' acquires all the rights as well as responsibilities that come with being a State Party to the Statute.'
								    ' These are substantive commitments, which cannot be taken lightly," she said. Rights group Human Rights'
								    ' Watch welcomed the development. "Governments seeking to penalize Palestine for joining the ICC should'
								    ' immediately end their pressure, and countries that support universal acceptance of the court\'s treaty'
								    ' should speak out to welcome its membership," said Balkees Jarrah, international justice counsel for the'
								    ' group. \"What\'s objectionable is the attempts to undermine international justice, not Palestine\'s'
								    ' decision to join a treaty to which over 100 countries around the world are members." In January, when'
								    ' the preliminary ICC examination was opened, Israeli Prime Minister Benjamin Netanyahu described it as an'
								    ' outrage, saying the court was overstepping its boundaries. The United States also said it "strongly"'
								    ' disagreed with the court\'s decision. \"As we have said repeatedly, we do not believe that Palestine is a'
								    ' state and therefore we do not believe that it is eligible to join the ICC," the State Department said in'
								    ' a statement. It urged the warring sides to resolve their differences through direct negotiations. "We'
								    ' will continue to oppose actions against Israel at the ICC as counterproductive to the cause of peace,"'
								    ' it said. But the ICC begs to differ with the definition of a state for its purposes and refers to the'
								    ' territories as "Palestine." While a preliminary examination is not a formal investigation, it allows the'
								    ' court to review evidence and determine whether to investigate suspects on both sides. Prosecutor Fatou'
								    ' Bensouda said her office would "conduct its analysis in full independence and impartiality." The war'
								    ' between Israel and Hamas militants in Gaza last summer left more than 2,000 people dead. The inquiry'
