opencv-contrib-python-headless VS opencv-contrib-python

[Johndirr]

Would be nice if keras-ocr would use opencv-contrib-python instead of the headless version. Because the headless version does not have any GUI functionality. This way a user don't has to uninstall and install the desired opencv packages if he wants to have opencv gui functionalities.
What do you think?

keras-ocr doesn't specify OpenCV as a dependency in setup.cfg / setup.py for the reason you suggest: I agree that users should be able to choose which flavor and version of the OpenCV package they wish to use. The reason that opencv-python-headless gets installed is because of the dependency on imgaug, for which I've already filed aleju/imgaug#473. It seems the compromise was to look for an existing OpenCV install first but that it doesn't seem to be working.

In other words, I'm not sure there's anything we can do in this package to remedy the matter. Let me know what you think.

Since we can't do much about it maybe a note in the readme for the used opencv flawor is enough.
