Hello,

I followed your guide to install opencv3, and everything finished without error. However, when I checked the version, it still said "2.4.9". Does the install change if OpenCV 2.4.9 was already installed on my system?

I have tried installing opencv3 through anaconda before this, so I'm not sure if that is what is getting in the way or not.

Thanks, Cody

Hi Cody;

Unfortunately I'm not that familiar with Anaconda, but it seems that there's OpenCV 3.1 packages. I would assume that reinstalling would indeed change the version number though...

What happens if you fully uninstall the OpenCV package before installing OpenCV 3?

Edit: Out of curiosity, do you know if Anaconda uses a virtual env, or the Python packages installed on the system?

@Cody-McClintock The conda package for opencv 3.2.0 is here

I would suggest you follow the simple steps given on this guide. The anaconda build has always failed for me. The zip file for opencv 3.2.0 can be found here. You can uninstall the opencv you already have, or run the steps on a ubuntu docker image to avoid conflicts.
