aesara-nightly 2.5.3.dev20220402

Optimizing compiler for evaluating mathematical expressions on CPUs and GPUs.

Aesara is a Python library that allows you to define, optimize, and efficiently evaluate mathematical expressions involving multi-dimensional arrays. It is built on top of NumPy. Aesara features:

• tight integration with NumPy: a similar interface to NumPy’s. numpy.ndarrays are also used internally in Aesara-compiled functions.

• transparent use of a GPU: perform data-intensive computations up to 140x faster than on a CPU (support for float32 only).

• efficient symbolic differentiation: Aesara can compute derivatives for functions of one or many inputs.

• speed and stability optimizations: avoid nasty bugs when computing expressions such as log(1 + exp(x)) for large values of x.

• dynamic C code generation: evaluate expressions faster.

• extensive unit-testing and self-verification: includes tools for detecting and diagnosing bugs and/or potential problems.
