Sure it can. Just use pip. There are even binary manylinux wheels! https://pypi.org/project/opencv-python/ There's a numpy in the stretch repos, https://packages.debian.org/stretch/python3-numpy - but indeed, the python3-opencv package doesn't arrive until buster. -- https://mail.python.org/mailman/listinfo/python-list
