abICS

abICS

abICS is a software framework for training a machine learning model to reproduce first-principles energies and then using the model to perform configurational sampling in disordered systems. Specific emphasis is placed on multi-component solid state systems such as metal and oxide alloys. The current version of abics can use neural network models implemented in aenet to be used as the machine learning model. As of this moment, abICS can also generate Quantum Espresso, VASP, and OpenMX input files for obtaining the reference training data for the machine learning model.

Requirement

• python3 (>=3.9)
• numpy
• scipy
• toml (for parsing input files)
• mpi4py (for parallel tempering)
  • This requires one of the MPI implementation
• pymatgen (>=2022.1.20) (for using Structure as a configuration)
  • This requires Cython
• qe-tools (for parsing QE I/O)

Install abICS

Pymatgen requires Cython but Cython will not be installed automatically, please make sure that this is installed,

$ python3 -m pip install Cython

mpi4py requires one of the MPI implementations such as OpenMPI, please make sure that this is also installed. In the case of using homebrew on macOS, for example,

$ brew install open-mpi

After installing Cython and MPI,

$ python3 -m pip install abics

will install abICS and dependencies.

If you want to change the directory where abICS is installed, add --user option or --prefix=DIRECTORY option to the above command as

$ python3 -m pip install --user abics

For details of pip , see the manual of pip by python3 -m pip help install
