[Orange] is a component-based data mining software. It includes a range of data
visualization, exploration, preprocessing and modeling techniques. It can be
used through a nice and intuitive user interface or, for more advanced users,
as a module for the Python programming language.

This is a development version of Orange 3. The stable version 2.7 is still
available ([binaries] and [sources]).

Installing
----------
This version of Orange requires Python 3.4 or newer. To build it and install
it in a development environment, run:

# Install some build requirements via your system's package manager
sudo apt-get install virtualenv git python3-dev g++ gfortran \
libblas-dev liblapack-dev libatlas-base-dev

# 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

# Finally install Orange in editable/development mode.
pip install -e .

Installation of SciPy and qt-graph-helpers is sometimes challenging because of
their non-python dependencies that have to be installed manually. More
detailed, if mostly obsolete, guides for some platforms can be found in
the [wiki].

Starting Orange GUI
-------------------

Orange GUI requires PyQt, which is not pip-installable in Python 3. You
have to download and install it system-wide. Make sure that the virtual
environment for orange is created with `--system-site-packages`, so it will
have access to the installed PyQt4.

To start Orange GUI from the command line, assuming it was successfully
installed, run:

orange-canvas
# or
python3 -m Orange.canvas

Append `--help` for a list of program options.


Windows dev setup
-----------------

Windows + GCC:

python setup.py build_ext --inplace --compile=mingw32
