Python 3.5 brings support for async programming in Python making it possible to use async web programming.
These instructions should work on Ubuntu 16.04 and Debian Stretch,
in older versions the OpenCV build will pick up Python 3.4 and this is going to result in mess.
Install Python:
apt-get install cmake wget python3.5-dev build-essential unzip \
libjpeg-dev libtiff5-dev libjasper-dev libpng12-dev \
libavcodec-dev libavformat-dev libswscale-dev libv4l-dev \
libgtk-3-dev python3-setuptools
Install pip:
wget https://bootstrap.pypa.io/get-pip.py python3 get-pip.py
Install numpy:
CFLAGS="-O3 -march=core-avx-i" pip3 install numpy
Install OpenCV:
wget https://github.com/Itseez/opencv/archive/3.1.0.zip unzip 3.1.0.zip cd opencv-3.1.0 mkdir build cd build CFLAGS="-pipe -O3 -march=core-avx-i" CFLAGS="-pipe -O3 -march=core-avx-i" cmake -D INSTALL_PYTHON_EXAMPLES=ON -D WITH_XIMEA=BOOL:ON ..
Observe the output of the last command and make sure CMake detected Python 3.5. Finally build OpenCV and install it
make -j32 sudo make install
