Python code for Biometric Evaluation metrics

I need a python functions that evaluate biometric system after features extracted from a deep model. The metrics for identification case are accuracy and CMC. The metrics for verification case are FAR, FPR, DET with different thresholds, and EER.
The graphs of CMC and DET should be plotted
I need 2 functions one for identification and another for verification should have those parameters; testing set, gallery set
