Recent advancements have established tensor network states (TNS) as formidable tools for exploring the
complex realm of strongly-correlated many-particle systems in both one and two dimensions. To tackle the
challenges presented by strongly-correlated fermion systems, various fermion tensor network states (f-TNS)
methodologies have been developed. However, implementing f-TNS methods poses substantial challenges due to
their particularly complex nature, making development efforts significantly difficult. This complexity is further
exacerbated by the lack of underlying software packages that facilitate the development of f-TNS. Previously,
we developed TNSPackage, a software package designed for TNS methods. Initially, this package was only
capable of handling spin and boson models. To confront the challenges presented by f-TNS, TNSPackage has
undergone significant enhancements in its latest version, incorporating support for both symmetry and fermion
tensors. This updated version provides a uniform interface for the consistent management of tensors across boson,
fermion, and various symmetry types, maintaining its user-friendly and versatile nature. This greatly facilitates
the development of programs based on f-TNS. The new TNSP framework consists of two principal components: a
low-level tensor package named TAT, which supports sophisticated tensor operations, and a high-level interface
package called tetragono that is built upon TAT. The tetragono package is designed to significantly simplify
the development of complex physical models on square lattices. The TNSPackage framework enables users to
implement a wide range of physical models with greater ease, without the need to pay close attention to the
underlying implementation details.
