- theano sub-module of theano, used for deep learning. rank: prepared types for rank 0 to 4. higher ranks (>4) tensor must be self-defined. type: dense operations: documentation
- pytensor the implementation is based on MatLab Tensor Toolbox
- scikit-tensor rank: type: dense and sparse operations: folding/unfolding, tensor-matrix and tensor-vector products, and tensor factorizations
