Orange3 - 开源机器学习和数据可视化工具
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 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.
First, install Anaconda for your OS (Python version 3.5+). Create virtual environment for Orange:
conda create python=3 --name orange3
In your Anaconda Prompt add conda-forge to your channels:
conda config --add channels conda-forge
This will enable access to the latest Orange release. Then install Orange3:
conda install orange3
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
To start Orange GUI from the command line, assuming it was successfully installed, run:
orange-canvas # or python3 -m Orange.canvas
--help for a list of program options.
Windows + GCC:
python setup.py build_ext --inplace --compile=mingw32
