Check you can run test.py
using both python 2 and 3 to verify that OpenCV python bindings were successfully installed

WARNING: Users of boards with 1GB of memory
Compiling is very memory intensive, you will likely need to increase your swap size. Assuming you have a reasonably large SD card (>16GB to be safe), follow the procedure below to increase your swap size from the default 100MB to 2GB
$ sudo dphys-swapfile swapoff
$ sudo sed -i 's:CONF_SWAPSIZE=.*:CONF_SWAPSIZE=2048:g' /etc/dphys-swapfile
$ sudo reboot
@texasStronger,
I haven't tried it, but probably worth copying the entire
~/opencv
dir and seeing whether you can just runsudo make install
from the build dir. Alternatively I believe you might be able to make some deb files using cpack, I've tried before but it wasn't particularly straight forward.Here's a few refs that might be of help
Let us know if you have any luck, if you manage it and it's not too complicated then I might update these script to build deb packages.
