Are venn-ABERS useful for p0 and p1

[Usmaniatech]

I want to calibrate the probabilities my model returns. My model already return the p0 and p1.

Looking at p0,p1 = ScoresToMultiProbs(calibrPts,testScores)

It seems that Venn_ABERS is for classifiers that return a classification score instead of probabilities (p0 and p1)
