I know there is a save command for the KNN classifier, that outputs the model in XML.

Is there any corresponding load command to load that model back into python

I am using cv2 3.0.0 and Python 2.7

This code save an img as xml but should be similar in your case:

import cv2
import numpy as np

img = cv2.cv.LoadImage('0.jpg',0)
cv2.cv.Save('sof.xml',img)
e=cv2.cv.Load("sof.xml")

print e

deprecated cv2.cv does no more exist in opencv3 (and you must not use it)

nvm, it's nice, that you're trying to help ! ;) (it's just not the correct answer. there have been efforts taken for SVM and ANN to add a model = XXX_save() method, unfortunately not for knn.)
