I'm getting this error when trying to use cv.ExtractSURF:
cv2.error: OpenCV was built without SURF support
I found the solution for c++ in this topic:
OpenCV SURF function is not implemented

---Edit---
When I try to run the example find_obj.py which uses cv2.SURF(800) I get the following error:
AttributeError: 'module' object has no attribute 'SURF'

It seems that some functions are moved to "nonfree" module and that module is removed from the latest OpenCV package on FC18. Until this will be resolved, I made downgrade OpenCV library on my 64bit FC18 from version 2.4.3 to version 2.3.1. With downgraded library, all my python code started to work as it worked on FC17. Here is link to my post where I have described complete "downgrade" procedure:
