AUC calculation

[loveis98]

Hello Why you treats scores like this (in perf_eva() function)?

if np.mean(pred) < 0 or np.mean(pred) > 1:
        warnings.warn('Since the average of pred is not in [0,1], it is treated as predicted score but not probability.')
        pred = -pred

I mean string pred = -pred exactly

In case of positive scores your computing works incorrectly

You can try to use the score as pred parameter to calculate the AUC value. It will return the right value.
