pyttb: Python Tensor Toolbox

The Python Tensor Toolbox (pyttb) is a refactor of the Tensor Toolbox for MATLAB in Python. This package contains data classes and methods for manipulating dense, sparse, and structured tensors, along with algorithms for computing low-rank tensor decompositions. Tensors (also known as multidimensional arrays or N-way arrays) are used in a variety of applications ranging from chemometrics to network analysis.
