i used python code opencv character recognition error while running code.

attributeerror: 'module' object has no attribute 'knearest'

since new opencv's version need replace

model = cv2.knearest() 

by:

model = cv2.ml.knearest_create() 

moreover, line:

model.train(samples,responses) 

is going raise error, should fix it:

model.train(samples,cv2.ml.row_sample,responses) # might adapted 

hope help.
