This repository provides unofficial binary wheels for Pymol-open-source for Python on Windows.

PyMOL(tm) is a visualization software for rendering and animating 3D molecular structures. PyMOL is a trademark of Schrodinger, LLC.

The files are unofficial (meaning: informal, unrecognized, personal, unsupported, no warranty, no liability, provided "as is") and made available for testing and evaluation purposes.

Source code changes, if any, have been submitted to the project maintainers or are included in the wheels.

The wheels can be downloaded from the Releases page.

Install a wheel on the command line, for example for Python 3.12 64-bit:

py.exe -3.12 -m pip install pymol-3.1.0a0-cp312-cp312-win_amd64.whl

Start the Pymol app using the pymol.exe executable in Python's script folder or from the command line:

py.exe -3.12 -m pymol

The Microsoft Visual C++ Redistributable packages for Visual Studio 2022 is required to run the software.

The pymol-open-source package conflicts with the chempy package. Only one library can be imported in a process.
