pip3 install opencv is looking at the wrong URL

Question

I'm trying to install opencv with pip3 on my Devuan GNU/Linux 3, and this is what happens:

$ pip3 install opencv
Collecting opencv
Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: https://pypi.org/simple/opencv

and indeed, if you browse that URL, you get a 404 page.

Why is this happening? Am I to blame? Devuan? pypi.org administrators? Somebody else?

Also - can I replace the URL somehow? Or manually install from somewhere?

`pip3 install opencv-python`. The package is not called `opencv` sicne it's a Python binding. — hoefling, May 30 '20 at 12:43

You can download the OpenCV source file and install it using pip. The installation file will have a .whl or Wheel filetype. You can download this one if you're on x86_64

Now go to the download location and type -

pip3 install opencv

Press Tab for auto-completion of the filename. It should be easily installed this way.

You mean, it'll be a file which begins with opencv? Also, is the second link the result of a build of the source in the first link? – einpoklum Apr 28 '20 at 08:00
Yes you are absolutely right – rubaiat Apr 28 '20 at 14:40

The package is named opencv-python on PyPI, so install it instead of non-existent opencv:

pip3 install opencv-python
