('Python bindings for the Qt cross-platform application and UI framework',)

Project description



PySide is the Python Qt bindings project, providing access to the complete Qt 5.12+ framework as well as to generator tools for rapidly generating Python bindings for any C++ libraries.

The PySide project is developed in the open, with all facilities you'd expect from any modern OSS project such as all code in a git repository and an open design process. We welcome any contribution conforming to the Qt Contribution Agreement.


Since the release of the Technical Preview it is possible to install via pip, both from Qt's servers and PyPi:

pip install PySide2


PySide versions following 5.12 use a C++ parser based on Clang. The Clang library (C-bindings), version 6.0 or higher is required for building. Prebuilt versions of it can be downloaded from

After unpacking the archive, set the environment variable LLVM_INSTALL_DIR to point to the folder containing the include and lib directories of Clang:

7z x .../libclang-release_60-linux-Rhel7.2-gcc5.3-x86_64-clazy.7z
export LLVM_INSTALL_DIR=$PWD/libclang

On Windows:

7z x .../libclang-release_60-windows-vs2015_64-clazy.7z

Building from source

For building PySide2 from scratch, please read about getting started. This process will include getting the code:

git clone
cd pyside-setup
git branch --track 5.12 origin/5.12
git checkout 5.12

then install the dependencies, and following the instructions per platform. A common build command will look like:

python install --qmake=<path/to/qmake/> --jobs=8 --build-tests

You can obtain more information about the options to build PySide and Shiboken in our wiki.

Documentation and Bugs

You can find more information about the PySide2 module API in the official Qt for Python documentation.

If you come across any issue, please file a bug report at our JIRA tracker following our guidelines.


Check #qt-pyside, our official IRC channel on FreeNode, or contact us via our mailing list.
