• Also install Qt dependencies for the GUI

sudo apt-get install python3-pyqt4

• Create a separate Python environment for Orange and its dependencies, and make it the active one

virtualenv --python=python3 --system-site-packages orange3venv
source orange3venv/bin/activate

• Clone the repository and move into it

git clone https://github.com/biolab/orange3.git
cd orange3

• Install the minimum required dependencies first

pip install numpy  
pip install scipy  
pip install -r requirements-core.txt  # For Orange Python library  
pip install -r requirements-gui.txt   # For Orange GUI  
pip install -r requirements-sql.txt   # To use SQL support  
pip install -r requirements-opt.txt   # Optional dependencies, may fail  
                                      #Command "python setup.py egg_info" failed with error code 1 in   #/tmp/pip-build-5sa29r7t/qt-graph-helpers/
