  # We make pyscf optional in this package, due to difficulties packaging it in Nix (test failures, complicated flags, etc).

  # or use the Nix User Repository version (https://github.com/drewrisinger/nur-packages).
  # It can also be installed at runtime from the pip wheel.
  # We disable appropriate tests below to allow building without pyscf installed
