Install OpenCV and Chainer on Ubuntu

environment
Ubuntu 14.04.4 LTS

Purpose

I want to get a face from an image and analyze who it is. To that end, first set up the environment.

Don't do

Video analysis is not performed with OpenCV. So I don't put in video related packages as much as possible.

What to put

What to put
Python 3.4.3
OpenCV 3.0.0
Chainer 1.10.0

Update the environment to the latest

$ sudo apt-get update
$ sudo apt-get upgrade

Insert pytnon3

Check the version already included

$ python -V

Installation

$ sudo apt-get install build-essential
$ sudo apt-get install python3-dev

Check version

$ python -V
$ python3 -V

Also install pip

$ sudo apt-get install python3-pip
$ pip3 -V
$ pip3 list

Insert OpenCV

Install the required packages

$ sudo apt-get -y install libopencv-dev build-essential cmake git libgtk2.0-dev pkg-config python-dev python-numpy libdc1394-22 libdc1394-22-dev libjpeg-dev libpng12-dev libtiff4-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev libtbb-dev libqt4-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils unzip
$ sudo apt-get -y install build-essential libopenexr-dev python-tk libtbb-dev libeigen3-dev yasm libfaac-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev libqt4-dev libqt4-opengl-dev sphinx-common texlive-latex-extra default-jdk ant libvtk5-qt4-dev unzip
$ sudo apt-get -y install libdc1394-22-dev libdc1394-22 libdc1394-utils

download

$ cd ~
$ wget -O opencv-3.0.0.zip https://github.com/Itseez/opencv/archive/3.0.0.zip
$ unzip opencv-3.0.0.zip

Creating CMake

$ cd opencv-3.0.0
$ mkdir build
$ cd build
$ sudo cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_NEW_PYTHON_SUPPORT=ON -D INSTALL_PYTHON_EXAMPLES=ON -D PYTHON_EXECUTABLE=$(which python3) -D BUILD_opencv_python3=ON -D BUILD_opencv_python2=ON BUILD_EXAMPLES=ON -D WITH_FFMPEG=OFF -D  BUILD_opencv_java=OFF BUILD_opencv_test_java=OFF ..

   General configuration for OpenCV 3.0.0 =====================================
  
abridgement
  
     Python 3:
       Interpreter:                 /usr/bin/python3.4 (ver 3.4.3)
       Libraries:                   /usr/lib/x86_64-linux-gnu/libpython3.4m.so (ver 3.4.3)
       numpy:                       /usr/local/lib/python3.4/dist-packages/numpy/core/include (ver 1.11.1)
       packages path:               lib/python3.4/dist-packages
  
     Python (for build):            /usr/bin/python3
  
abridgement
  
     Install path:                  /usr/local
  
     cvconfig.h is in:              /home/ubuntu/opencv-3.0.0/build
   -----------------------------------------------------------------

Build & install

$ sudo make
$ sudo make install

Add Path

$ sudo vi /etc/ld.so.conf.d/opencv.conf
  /usr/local/lib
  /usr/lib

Reload & confirm Path

$ sudo ldconfig 
$ ldconfig -v

Check version

$ python3 -c "import cv2;print(cv2.__version__)" 

If you get a libdc1394 error

$ sudo ln /dev/null /dev/raw1394

Insert Chainer

Installation

$ sudo pip3 install chainer

Install the required packages

$ sudo apt-get install python3-numpy python3-scipy
$ sudo pip3 install -U scikit-learn

Be able to image the analysis results

$ sudo pip3 install matplotlib

Check version

$ python3 -c "import chainer;print(chainer.__version__)" 

end

I was surprised that Chainer entered very smoothly. I'll use it now.
