AttributeError: 'module' object has no attribute 'xfeatures2d'?

I want to use the sift function in open cv, when I do:

cv2.xfeatures2d

I get:

AttributeError: 'module' object has no attribute 'xfeatures2d'

even cv2.SIFT() does not work. However this seems to work:

cv2.orb_create()

I am on open cv 3.3.0, using opencv-contrib-python. I tried using opencv-python but that also gave me same errors.

I tried uninstalling and reinstsalling as well using pip. I am on osx.

First install opencv-python and opencv-contrib-python:

For python2:

$(sudo) python2 -m pip install opencv-python opencv-contrib-python

For python3:

$(sudo) python3 -m pip install opencv-python opencv-contrib-python

Then call try again. For OpenCV 3.x, use cv2.xfeatures2d.SIFT_create() to create:

$ python
>>> import cv2 
>>> cv2.__version__
'3.3.0-dev'
>>> sift = cv2.xfeatures2d.SIFT_create()
>>> sift
<xfeatures2d_SIFT 0x7f79ca721d10>
