Compute AUPRC?

[2533245542]

Currently I could only use torchmetrics.classification.PrecisionRecallCurve. Is there an easy way to compute AUPRC from it?

You can use the torchmetrics.classification.PrecisionRecallCurve to get the precision recall curve and afterwards use the auc implementation (https://torchmetrics.readthedocs.io/en/latest/references/functional.html#auc-func) to get the AUPRC value.

@SkafteNicki I don't think this method works anymore. Do you know how we can obtain the AUPRC from the precision recall curve? I could use the AUC function from sklearn but I don't think if that will has the same set of lighting features.

@angerhang, why do you assume that it does not work?
