some examples are ok but with digits.py , SVM or KNearest syntax issues

> ../data/digits.png ...
> preprocessing... training KNearest...
> Traceback (most recent call last):  
> File "digits.py", line 173, in
> <module>
>     model = KNearest(k=4)   File "digits.py", line 81, in __init__
>     self.model = cv.ml.KNearest_create()
> AttributeError: 'module' object has no attribute 'ml'

with cv.KNearest() it's ok but after ...other error it seems version issues but how to resolve ? thanks for help
