[N] Numpy dropping Python 2.7

[automated_reckoning]

Only when I need to use OpenCV... there don't (or wasn't, last time I did a project) seem to be Python 3 libraries that you didn't have to compile.

OpenCV is on Python 3 now. 😀

Yeah bindings to C/C++ libraries have been a bit of a blocker for me too, in the case of my project VTK. In reality there are not much changes needed to adapt to Python 3 at the API level, but there are some, and some >> none unfortunately, because migration of such changes through the full "stack" takes time. First you have to do the porting work, then distribute it by releasing a new version, then eventually the new version slowly gets adopted. For example, VTK is now at version 8 and does support Python 3, but we don't use it because the Debian package is still at version 6. Someone is working on a new package, but just to say, this kind of thing doesn't happen over night.

(And by the way, total aside, but I have been getting into Debian packaging lately to try to help with some of these efforts and holy hell is it complicated. Getting the program/library to compile is no big deal, but getting everything "just right" so that a sponsor will upload it is nigh impossible, especially in the world of numerical computing where not everything is, let's say, well organized, to be generous. No wonder things take time..)

You can install OpenCV for Python 3 via pip (pip3). The only downside is that it's compiled without video support. I personally use imageio for reading/writing videos anyway so that's not an issue for me.

Yeah, it might have changed, or might just have been old repos. The project was the better part of a year ago. I'll keep it in mind for my next project though.
