opencv-contrib-python-3.4.3.18 doesn't contain SIFT module ?

Expected behaviour

I use python3.6.5 amd64 and opencv-contrib-python-3.4.3.18, seems that "SIFT" module is not in this lib...

It works fine in opencv-contrib-python-3.4.2.17, like below:

Actual behaviour

Steps to reproduce

• example code:

import cv2
sift = cv2.xfeatures2d.SIFT_create(edgeThreshold=10)

• Win7 64bit Professional
• python amd64
• opencv-contrib-python-3.4.3.18
