static build(orbital_basis, aux=None, jk_type=None, do_wK=None, memory=None)

Constructs a Psi4 JK object from an input basis.

  • orbital_basis (BasisSet) – Orbital basis to use in the JK object.
  • aux (BasisSet, optional) – Optional auxiliary basis set for density-fitted tensors. Defaults to the DF_BASIS_SCF if set, otherwise the correspond JKFIT basis to the passed in orbital_basis.
  • jk_type (str, optional) – Type of JK object to build (DF, Direct, PK, etc). Defaults to the current global SCF_TYPE option.

Uninitialized JK object.

Return type:



jk = jk.set_memory(int(5e8)) # 4GB of memory jk.initialize()

jk.C_left_add(matirx) jk.compute() jk.C_clear()
