Comment (by fmw42):

 Thanks. I was wondering what all those versions of pyXX-opencv3 were
 about. I have followed your instructions to uninstall opencv and reinstall
 both py37-opencv3 and py39-opencv3. My Python37 scripts now work. But they
 do not work when using Python39. I will post a new bug report (about
 Numpy).

 I appreciate your quick response.
