Sometimes pip install is very slow, because it is compiling.

 

$ cd ~/opencv && mkdir build && cd build

$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=ON -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules -D BUILD_EXAMPLES=ON ..

$ make -j4

$ sudo make install && sudo ldconfig
