Build wheel fails for opencv-python-headless

[yahyaakli]

I am using docker Alpine linux and I've been having issues with building wheel for opencv-python-headless. Everytime I run it I get this error:

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for opencv-python-headless**

(I am using alpine:3.14)

This seemed to me as a code issue.

Please, do you have any feedback on this issue?

Thank you.

I'm trying to build and getting the exact same error. Using nvidia/cuda:10.2-cudnn7-devel-ubuntu18.04 image.

The PR mentioned #648 does solve the issue. Here's my output:
