🔥 RDKit Python Wheels

This repository holds the code to build RDKit platform wheels for Linux, macOS, and Windows on Github Action and Circle CI. The wheels contain the compiled platform-specific dynamic libraries (*.so, *.dylib, and *.dll) and are available at PyPI. RDKit can easily be installed using

pip install rdkit

Please open an issue if you find something missing or not working as expected.
