LAMMPS unofficial wheels

This unofficial repository holds the code to build LAMMPS platform wheels for Linux, macOS, and Windows. LAMMPS can easily be installed using

pip install lammps
# If you didn't install MPI
pip install lammps[mpi]

The package requires Python 3.7 and above. Most packages are enabled in this distribution. For the usage of LAMMPS, see LAMMPS documentation.

macOS	x86_64	64	>= macOS-11	MPICH

To use MPI, it is required to use the same MPI as what the package was built against.

Usage

Python

from lammps import PyLammps

Command line

lmp -h

Plugins

Developers should build plugins with the same MPI, and can register the plugin directory using the entry points:

[project.entry-points.'lammps.plugins']
some_plugin = "some_package:get_plugin_dir"

get_plugin_dir should return a string which contains the plugin directory and can be added into LAMMPS_PLUGIN_PATH. See LAMMPS plugin documentation for details.
