How to produce the evaluation matrices (accuracy, F1 score, precision) for one-class SVM?

I am creating a one-class SVM model for anomaly detection. However, I can't find the documentation to produce the evaluation matrices for the one-class SVM. Namely accuracy, F1 score, precision and confusion chart.
