Optimizing compiler for evaluating mathematical expressions

PyTensor is a fork of Aesara - a Python library that allows one to define, optimize, and efficiently evaluate mathematical expressions involving multi-dimensional arrays.

Features

  • A hackable, pure-Python codebase
  • Extensible graph framework suitable for rapid development of custom operators and symbolic optimizations
  • Implements an extensible graph transpilation framework that currently provides compilation via C, JAX, and Numba
  • Based on one of the most widely-used Python tensor libraries Theano
