Since it's managed by the Debian repo, you can simply look at its dependencies. In this case, python-opencv is built for Python 2, not Python 3, so it'll pull in Python 2.7.9-1. Unfortunately there isn't a corresponding python3-opencv package, so I don't know how hard it would be to install for Python 3.4.2; but personally, I'd just try using pip to install it. $ apt-cache show python-opencv Version: 2.4.9.1+dfsg-1+b1 Depends: python (<< 2.8), python:any (>= 2.7.5-5~), python (>= 2.7~), libc6 (>= 2.14), libgcc1 (>= 1:4.1.1), libopencv-calib3d2.4, libopencv-contrib2.4, libopencv-core2.4, libopencv-features2d2.4, libopencv-flann2.4, libopencv-highgui2.4, libopencv-imgproc2.4, libopencv-legacy2.4, libopencv-ml2.4, libopencv-objdetect2.4, libopencv-photo2.4, libopencv-video2.4, libpython2.7 (>= 2.7), libstdc++6 (>= 4.1.1), python-numpy-abi9, python-numpy (>= 1:1.6.1) If you simply "apt-get install python-opencv", it'll make sure you have the right Python installed.
