I wanted to install OpenCV for Python3 on my machine following this tutorial, but I'm faced with a problem of numpy version notation on Christoph Gohlke's website, more precisely what does for example
numpy‑1.14.2+mkl‑cp36‑cp36m‑win32.whl
notation mean, I don't understand what version I have to download. Which one of versions listed here do I install based on my system specs?
I've read through the header introduction on Christoph Gohlke's website but didn't find any explanation.
numpy‑1.14.2+mkl‑cp36‑cp36m‑win32.whl
numpy — well, obviously
1.14.2 — version of NumPy
mkl — compiled with Intel Math Kernel Library
cp36‑cp36m — for CPython version 3.6
win32 — for 32-bit Python on Windows (Windows could be 32- or 64-bit)
win_amd64 — for 64-bit Python on Windows (Windows must be 64-bit)
pp360 — PyPy3 version 6.0.
To see what Python you've installed run
python.exe -c "from pip._internal import pep425tags; print(pep425tags.get_supported())"
The output will be something like
[('cp27', 'cp27mu', 'linux_aarch64'), ('cp27', 'none', 'linux_aarch64'), ('py2', 'none', 'linux_aarch64'), ('cp27', 'none', 'any'), ('cp2', 'none', 'any'), ('py27', 'none', 'any'), ('py2', 'none', 'any'), ('py26', 'none', 'any'), ('py25', 'none', 'any'), ('py24', 'none', 'any'), ('py23', 'none', 'any'), ('py22', 'none', 'any'), ('py21', 'none', 'any'), ('py20', 'none', 'any')]
