"TeNPy is a package of Python code for the simulation of quantum many-body systems with tensor networks. Amongst others, it includes codes for the density matrix renormalization group (DMRG) algorithm and the time evolving block decimation (TEBD) algorithm based on matrix product states (MPS). The minimal dependency is Python, Numpy and Scipy, but it ships with an optional Cython extension to reduce the Python overhead in tensor contractions."
