I have to read a YAML file in python using opencv 3.0 . I have found this solution in one of the previous questions but it is not applicable for version 3.0:

yaml_data = numpy.asarray(cv2.cv.Load("my_file.yaml"))

It seems that cv2.cv has been removed, can anyone tell me where is it now?

cv2.cv is gone entirely.

what are you trying to load ?

Indeed. A colleague of mine has produced some YML using opencv, I have to read them.

any chance, you can remove the yaml headers, and read it in as csv or such ?

sad as it is, you need some gross hack here...

I was hoping not to read this answer... :(

Apparently there is this function:

fs = cv2.FileStorage("my_file.yml", 0)

However it is not clear how to use it: the code I have found here: https://github.com/opencv/opencv/pull/6482 does not work on my system, it keep saying FileStorage has no attribute 'getNode'

indeed then, if you want to use cv2.FileStorage properly, you'd need a version later than the merge date(31 May)
