🔥 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

NOTE: Older versions of RDKit might be available at the rdkit-pypi PyPI repository (pip install rdkit-pypi). rdkit-pypi is the old name of this project at PyPI. Future RDKit versions will be available at the rdkit PyPI repository. Please update your dependencies, i.e., change rdkit-pypi to rdkit.

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