OBEU Data Analysis and Mining repository


This repository hosts implementation of the OBEU Data Analysis and Mining (The ten tasks defined in D2.3). Currently, it has three branches: master, staging, and production. OBEU Partners are encouraged to create their own branches for doing testing (Python, Java, etc.), better just use their personal name as the branch name.

Work flow

Three main sub-tasks

  • A OBEU lib for data analysis and mining

  • Web page development for each task

  • Communication with other modules/system (Visualization, Triple store, Openspending)

Code and Architecture

To consistent with OpenSpending, we use Flask + Python at the backend, javascript(currently bootstrap) at the frontend.

How to run

  • install R ** using brew brew tap homebrew/science brew install r

  • Clone the GitHub repository: git clone and $ git checkout tiansi

  • Install and setup postgresql

# on osx, configures postgres without security measures from localhost and creates a user for your UID
brew install postgres

# on [debian/ubuntu] linux
apt-get install postgres

psql postgres
CREATE DATABASE openbudgets WITH OWNER=<username-is-usually-your-login-name>
$ python3 -V
$ Python 3.5.2
  • In order to install the project dependencies you will need the following packages sudo apt-get install python3-dev build-essential python-psycopg2 libpng-devel postgresql-devel (Mac os user skip this)

  • Install autoenv

$ pip install autoenv
$ echo "source `which`" >> ~/.bashrc
  • Install virtualenv: pip install virtualenv

  • Afterwards create a virtual environment for your project and go to the project's folder

$ virtualenv env
$ cd DAM
  • Setup environment variables
export APP_SETTINGS=config.DevelopmentConfig # to tell the server to startup in development mode
export DATABASE_URL=localhost/openbudges # or whatever you used above as postgres DB
  • Install all application requirements by executing pip install -r requirements.txt

  • Start your application by executing python runserver

    in a new terminal, run redis-server

    in a new terminal, run python3

  • Go to http://localhost:5000

How to use Redis in a docker container

go to the directory where you want to install

clone the Redis image by typing git clone

then, cd dam_env && chmod +x && ./

in the file, change USE_DOCKER_REDIS = True

Possible error and Solutions

  • Error 1

RuntimeError: Python is not installed as a framework. The Mac OS X backend will not be able to function correctly if Python is not installed as a framework. See the Python documentation for more information on installing Python as a framework on Mac OS X. Please either reinstall Python as a framework, or try one of the other backends. If you are Working with Matplotlib in a virtual enviroment see 'Working with Matplotlib in Virtual environments' in the Matplotlib FAQ

  • Solution to Error 1

touch frameworkpython file in the virtualenv bin directory with the following content:


# what real Python executable to use

# find the root of the virtualenv, it should be the parent of the dir this script is in
ENV=`$PYTHON -c "import os; print(os.path.abspath(os.path.join(os.path.dirname(\"$0\"), '..')))"`

# now run Python with the virtualenv set as Python's HOME
exec $PYTHON "$@"

instead of running python runserver, run frameworkpython runserver

  • Solution 2 to Error 1

If you are using pyenv and pyenv virualenv you can simply install a python framework version:

env PYTHON_CONFIGURE_OPTS="--enable-framework CC=clang" pyenv virtualenv install <python_version>
# re-create the virtualenv
pyenv virtualenv [local] openbudgets


You can’t perform that action at this time.
