tn4ml 1.0.3

Tensor Networks for Machine Learning

Tensor Networks for Machine Learning

tn4ml is a Python library that handles tensor networks for machine learning applications. It is built on top of Quimb, for Tensor Network objects, and JAX, for optimization pipeline.
For now, the library supports 1D Tensor Network structures: Matrix Product State, Matrix Product Operator and Spaced Matrix Product Operator.
It supports different embedding functions, initialization techniques, and optimization strategies.

Installation

First create a virtualenv using pyenv or conda. Then install the package and its dependencies.

With pip (tag v1.0.2):

pip install tn4ml

or directly from github:

pip install -U git+https://github.com/bsc-quantic/tn4ml.git

If you want to test and edit the code, you can clone local version of the package and install.

git clone https://github.com/bsc-quantic/tn4ml.git
pip install -e tn4ml/
