sift = cv2.xfeatures2d.SIFT_create() not working even though have contrib installed

Question

So I am trying to use:

sift = cv2.xfeatures2d.SIFT_create()

and it is coming up with this error:

cv2.error: OpenCV(3.4.3) C         


        

Answer 1

I had the same problem. It seems that SIRF and SURF are no longer available in opencv > 3.4.2.16. I chose an older opencv-python and opencv-contrib-python versions and solved this problem. Here is the history version about opencv-python, and I use the following code :

pip install opencv-python==3.4.2.16
pip install opencv-contrib-python==3.4.2.16

Edit

For Anaconda User just this instead of pip

conda install -c menpo opencv

this will install cv2 3.4.1 and everything you need to run SIFT

good luck~
