I tried to install,, and, but failed with the same error.

Any help will be appreciated!

you don’t have to build.

either upgrade your OS, or use an earlier version of opencv, because there are packages that should work for your OS (10.14):

opencv v4.5.1: opencv-python · PyPI

that’s the latest opencv with packages that don’t require 10.15 or later.

if you want to build OpenCV, you build OpenCV. that contains python bindings. the opencv-python build stuff is for the self-contained package, which you don’t need. just build opencv itself.

I had exactly the same problem. Don’t know if it will apply to your case, but I tried installing open-cv-headless with conda and it worked for me !

conda install -c fastai opencv-python-headless
