Appears to be fixed after removing opencv-python as an extras_require.

Explanation:

The opencv-python package is actually a subset of opencv-contrib-python. Both packages are aliased as cv2 for import. If opencv-python is imported then no features of contrib are available. If opencv-contrib-python is imported then all features of contrib (and opencv-python) are available.
