cv2.version module #343

Closed jamesmyatt closed 7 months ago

jamesmyatt commented 1 year ago

The PyPI wheel include a cv2.version module, which is created at build-time using find_version.py. See https://github.com/opencv/opencv-python/tree/4.x#versioning. Would it be possible to include the same logic in the conda packages? Would it be a good idea? Parity with the pypi wheel seems like a good idea to me.

Most of all, I'm interested to in the cv2.version.headless attribute that shows whether cv2 has been compiled with the headless options or not.

I (and likely other maintainers) would accept patches to conda-forge to improve things on this front. I would ask that an attempt is made to upstream them.

The last one we tried to upstream was stalled: https://github.com/opencv/opencv/pull/21611 but I think that if you add your voice for more "official" support for these features, it would go a long way.

AFAIK there is no separate headless OpenCV package in conda-forge, see #293

Version string can be accessed directly as cv2.__version__ and more detailed information can be extracted from cv2.getBuildInformation()

I would like to close this as it seems that an adequate workaround was found.

Please feel free to re-open if you think there is an important usecase that you want to tackle.

We've recently released "headless" versions of opencv and would welcome feedback on them.
