BinaryDescriptor in Python/OpenCV

Question

My goal is to implement the tutorial as below. https://docs.opencv.org/4.7.0/df/dfa/tutorial_line_descriptor_main.html

I found BinaryDescriptor in OpenCV/Python. https://docs.opencv.org/4.x/dc/ddd/group__line__descriptor.html

I tried to use it, but failed.

bd = cv.createBinaryDescriptor()

But I only show the message:

AttributeError: module 'cv2' has no attribute 'createBinaryDescriptor'
