Chinese Chess reinforcement learning by AlphaZero methods.
This project is based on these main resources:
- DeepMind's Oct 19th publication: Mastering the Game of Go without Human Knowledge.
- The great Reversi/Chess/Chinese chess development of the DeepMind ideas that @mokemokechicken/@Akababa/@TDteach did in their repo: https://github.com/mokemokechicken/reversi-alpha-zero, https://github.com/Akababa/Chess-Zero, https://github.com/TDteach/AlphaZero_ChineseChess
- A Chinese chess engine with gui: https://github.com/mm12432/MyChess
In order to build a strong chinese chess AI following the same type of techniques as AlphaZero, we need to do this with a distributed project, as it requires a huge amount of computations.
If you want to join us to build the best chinese chess AI in the world:
- For instructions, see wiki
- For live status, see https://cczero.org
- Python 3.6.3
- tensorflow-gpu: 1.3.0
- Keras: 2.0.8
This AlphaZero implementation consists of two workers: self and opt.
selfis Self-Play to generate training data by self-play using BestModel.optis Trainer to train model, and generate new models.
For the sake of faster training, another two workers are involved:
slis Supervised learning to train data crawled from the Internet.evalis Evaluator to evaluate the NextGenerationModel with the current BestModel.
Requirement: pygame
python cchess_alphazero/run.py playScreenshots
You can choose different board/piece styles and sides, see play with human.
pip install -r requirements.txtIf you want to use CPU only, replace tensorflow-gpu with tensorflow in requirements.txt.
Make sure Keras is using Tensorflow and you have Python 3.6.3+.
PlayDataConfig
nb_game_in_file, max_file_num: The max game number of training data isnb_game_in_file * max_file_num.
PlayConfig, PlayWithHumanConfig
simulation_num_per_move: MCTS number per move.c_puct: balance parameter of value network and policy network in MCTS.search_threads: balance parameter of speed and accuracy in MCTS.dirichlet_alpha: random parameter in self-play.

optional arguments:
-h, --help show this help message and exit
--new run from new best model
--type TYPE use normal setting
--total-step TOTAL_STEP
set TrainerConfig.start_total_steps
--ai-move-first set human or AI move first
--cli play with AI with CLI, default with GUI
--gpu GPU device list
--onegreen train sl work with onegreen data
--skip SKIP skip games
--ucci play with ucci engine instead of self play
--piece-style {WOOD,POLISH,DELICATE}
choose a style of piece
--bg-style {CANVAS,DROPS,GREEN,QIANHONG,SHEET,SKELETON,WHITE,WOOD}
choose a style of board
--random {none,small,medium,large}
choose a style of randomness
--distributed whether upload/download file from remote server
--elo whether to compute elo score
python cchess_alphazero/run.py self
When executed, self-play will start using BestModel. If the BestModel does not exist, new random model will be created and become BestModel. Self-play records will store in data/play_record and BestMode will store in data/model.
options
--new: create new BestModel--type mini: use mini config, (seecchess_alphazero/configs/mini.py)--gpu '1': specify which gpu to use--ucci: whether to play with ucci engine (rather than self play, seecchess_alphazero/worker/play_with_ucci_engine.py)--distributed: run self play in distributed mode which means it will upload the play data to the remote server and download latest model from it
Note1: To help training, you should run python cchess_alphazero/run.py --type distribute --distributed self (and do not change the configuration file configs/distribute.py), for more info, see wiki.
Note2: If you want to view the self-play records in GUI, see wiki.
python cchess_alphazero/run.py opt
When executed, Training will start. The current BestModel will be loaded. Trained model will be saved every epoch as new BestModel.
options
--type mini: use mini config, (seecchess_alphazero/configs/mini.py)--total-step TOTAL_STEP: specify total step(mini-batch) numbers. The total step affects learning rate of training.--gpu '1': specify which gpu to use
View training log in Tensorboard
tensorboard --logdir logs/
And access http://<The Machine IP>:6006/.
Run with built-in GUI
python cchess_alphazero/run.py play
When executed, the BestModel will be loaded to play against human.
options
--ai-move-first: if set this option, AI will move first, otherwise human move first.--type mini: use mini config, (seecchess_alphazero/configs/mini.py)--gpu '1': specify which gpu to use--piece-style WOOD: choose a piece style, default isWOOD--bg-style CANVAS: choose a board style, default isCANVAS--cli: if set this flag, play with AI in a cli environment rather than gui
Note: Before you start, you need to download/find a font file (.ttc) and rename it as PingFang.ttc, then put it into cchess_alphazero/play_games. I have removed the font file from this repo because it's too big, but you can download it from here.
You can also download Windows executable directly from here. For more information, see wiki.
UCI mode
python cchess_alphazero/uci.py
If you want to play in general GUIs such as '冰河五四', you can download the Windows executable here. For more information, see wiki.
python cchess_alphazero/run.py eval
When executed, evaluate the NextGenerationModel with the current BestModel. If the NextGenerationModel does not exist, worker will wait until it exists and check every 5 minutes.
options
--type mini: use mini config, (seecchess_alphazero/configs/mini.py)--gpu '1': specify which gpu to use
python cchess_alphazero/run.py sl
When executed, Training will start. The current SLBestModel will be loaded. Tranined model will be saved every epoch as new SLBestModel.
About the data
I have two data sources, one is downloaded from https://wx.jcloud.com/market/packet/10479 ; the other is crawled from http://game.onegreen.net/chess/Index.html (with option --onegreen).
options
--type mini: use mini config, (seecchess_alphazero/configs/mini.py)--gpu '1': specify which gpu to use--onegreen: if set the flag,sl_onegreenworker will start to train data crawled fromgame.onegreen.net--skip SKIP: if set this flag, games whoses index is less thanSKIPwould not be used to train (only valid whenonegreenflag is set)
