abrain 1.0rc0

NeuroEvolution in Python backed by C++ computations

Artificial Brains (ABrain) for Python

Release

Development

C++/Python implementation of the genotype/phenotype components of Evolvable Substrate HyperNEAT (read without evolution and speciation).

Optional dependencies:

Graphviz (dot)

To generate directed graphs for the genomes Can only be fetched by system installer (apt-get, yum, ...) See https://graphviz.org/download/ for instructions

Kaleido

To generate non-interactive images of ANN (through plotly) Due to inconsistent support, left as an optional dependency Use pip install abrain[...,kaleido] to get it

Todo list:

• Functionalities:

  • Order-independent ANN evaluation (with back buffer)?
  • Crossover / historical markings
    • Actually needed?
  • MANN Integration
    • Easy extraction
    • built-in testing
    • C++ wrapper
    • Visu

• Misc:

  • Documentation

    • Usage

  • Continuous integration

    • build / tests
    • Badges

  • Packaging:

    • include c++ stubs?
    • move to scikit/poetry/... ?

  • Installation errors:

    • cp38,...,311-manylinux_i686 fail because cppn outputs diverge between manual and subset/all

      Caused by unmatched image/host platforms? Heisenbug, printing an FNode value before returning it makes it work Also disapears in when compiling in debug mode

    • pp38,39-manylinux_i686,x86_64; pp38,39-macosx_x86_64; pp38,39-win_amd64 fail because of strange import error in numpy

      Solved by removing numpy dependency

    • cp38,...,311-musllinux_i686 fail because pillow needs a jpeg library

      Solved? Added libjpeg to the apk (musllinux) install Removed pillow dependency

    • cp38,..,311-win32,amd64 fail because of encoding error in ANN rendering
