Installation

• Install stable release:

    pip install pyscf
  

• New features developed in recent years are available in the pyscf-forge package:

    pip install pyscf-forge
  

• Certain modules are maintained as extensions of PySCF, such as dispersion, dmrgscf, fciqmc, icmpspt, properties, semiempirical, shciscf ... (more on https://github.com/pyscf) can be installed using pip:

    pip install pyscf[all]
  

  An individual extension can be installed:

• More details of custom installation can be found in installation manual

Citing PySCF

Base PySCF

The following paper should be cited in publications utilizing the PySCF program package:

Density functional calculations

As PySCF does not implement density functionals, instead employing external libraries to handle their evaluation, these libraries should also be cited in publications employing PySCF for density functional calculations.

If your calculation employed Libxc, cite

Recent developments in libxc — A comprehensive library of functionals for density functional theory, Susi Lehtola, Conrad Steigemann, Micael J.T. Oliveira, and Miguel A.L. Marques, SoftwareX 7, 1 (2018). doi:10.1016/j.softx.2017.11.002

If your calculation employed XCFun, cite

Arbitrary-order density functional response theory from automatic differentiation, Ulf Ekström, Lucas Visscher, Radovan Bast, Andreas J. Thorvaldsen, and Kenneth Ruud, J. Chem. Theory Comput. 6, 1971 (2010). doi:10.1021/ct100117s
