Features

  • mathy: cleanup and remove dead code (ec686d9)

BREAKING CHANGES

  • mathy: This removes the MCTS powered agent. It was a nice agent but the pieces required for it to work effectively have been lost. It's not a primary use-case of mine now, so it's better to drop it and remove any confusion.

  • refactor(agents): move to singular agent with generic names

  • PolicyValueModel -> AgentModel
  • Remove embeddings model and make it part of AgentModel
  • refactor(model): replace custom keras model with functional
  • allows graphing model architecture for website
  • adds extra validation
  • allows full-model saving (without explicit optimizer save/loading)
  • refactor(model): move action masking out of the model
  • Soooo masking doesn't play well with full-model saving and loading, or functional models, or keras strict data validation. Drop it out of the model, and let the action selector do its own masking.
  • TODO: add a loss term for the mask in addition to the policy loss?

  • chore: misc cleanup and fix tests

  • chore: update tf_siren dep

  • chore: fix some tests and remove dead ones

  • refactor(core): use mathy_core for CAS needs

This moves a lot of complexity out to another package, which is desirable for a number of reasons:

  • when you only need to do CAS things, the mathy_core package can be installed without the need for larger things like TensorFlow or PyTorch which can make the install time much quicker
  • the build time for the Mathy repo goes down by however much time it took to compile and test the core mathy code.
  • it's easier to browse the code if you're unfamiliar with Mathy because it's not buried in a monorepo under a mountain of other folders

  • chore: fix website build

  • perf(ci): refactor virtual envs to reduce build time

  • share a root virtualenv to avoid double or triple installing hefty packages like TensorFlow and PyTorch

  • chore: remove ci specific setup script

  • chore: remove disk space cleanup step

  • it takes about a minute, and it's unclear if it's needed now that we share a root virtual env

  • chore: drop keras-self-attention dep

  • chore: fix requirements for tf agent

  • chore: fix requirements for mkdocs plugin

  • chore: install graphviz on ci build machine

  • chore: try tensorflow 2.2.0

  • I think this caused optimizer loading problems last time I tried to upgrade, but let's see

  • chore: fix import errors

  • chore: try to confirm siren fix

  • chore: remove kwargs from Sine layer

  • chore: remove second pytest invocation for zero

  • TensorFlow didn't mix too well with multiprocessing so I had to run the MP tests separately for the Zero agent.
  • Zero agent is gone, cya extra test invocation

  • chore: fix venv path in test scripts

  • chore: drop example apps from main package

  • will add them later as mathy org repositories
  • update API docs
  • drop some unused queues

  • chore: drop reformer test

  • chore: bump tf_siren to 0.0.5 for tf2.2

  • chore: drop misc cleanup

  • test(cli): better coverage for generating problems

  • chore: cleanup from review

  • chore: cleanup from review

BREAKING CHANGES: This removes the "zero" agent entirely, and invalidates existing pretrained mathy models.
