In [29]: cv2.KNearest()
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-29-d2ea29abad59> in <module>()
----> 1 cv2.KNearest()
AttributeError: 'module' object has no attribute 'KNearest'
In [30]: cv2.K
cv2.KAZE_DIFF_CHARBONNIER cv2.KAZE_DIFF_WEICKERT cv2.KMEANS_RANDOM_CENTERS cv2.KeyPoint
cv2.KAZE_DIFF_PM_G1 cv2.KAZE_create cv2.KMEANS_USE_INITIAL_LABELS cv2.KeyPoint_convert
cv2.KAZE_DIFF_PM_G2 cv2.KMEANS_PP_CENTERS cv2.KalmanFilter cv2.KeyPoint_overlap
解决方案
许多模块已从OpenCV核心中删除,并标记为非空闲.这些模块具有单独的存储库,必须分别构建.

解决方案
Many modules were removed from OpenCV core and marked as nonfree. These modules have separate repository and has to be built separately.
The repository is here https://github.com/itseez/opencv_contrib/
