El Capitan Python 2.7.15 DVR-Scan Installation Issue

[daBee]

I'm on a Mac El Capitan 10.11 box. Very much want to use this software, or at least try it out. Looks great. I can't get all this working, and I know nothing about Python.

Yes I'm on an old box. Any chance this could be something simple I could chase?

Hi i have a feeling that i installed this against Python3 which was itself installed from Homebrew to get it to work. I am on Mojave but cant see any reason why this wouldnt work on El Capitan.
If you just install Python3 from Homebrew then use sudo pythonr setup.py install it should work.
If not can you post any output?

I don't even remember posting this, to be honest. I have moved on.

Sorry I didn't see this until now...

This is likely because when DVR-Scan was written, I didn't actually include the OpenCV package as a requirement, as at the time there was no binary distribution available on pip that worked reliably on all platforms. This has since changed, and I should likely update the required packages. I'll open a new issue to reflect this.

Thanks for the report.
