Bug Fixes

• cli: simplify command without fragile installed (c4dfcec)

0.8.0 (2020-07-24)

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.
