You can find the codes for the simple two-electron case at http://compphysics.github.io/ComputationalPhysics2/doc/LectureNotes/_build/html/boltzmannmachines.html.

The trial wave function is based on the product of a Slater determinant with either only Hermitian polynomials or Gaussian orbitals, with and without a Pade-Jastrow factor (PJ).
