Execute main.py

$ python main.py

Read an mjai-log

You can read an mjai-log in log directory by

File > Open

Play a game

You need to copy following from akochan(https://github.com/critter-mj/akochan)

ai.dll (windows)
libai.so (linux)
system.exe
setup_mjai.json
params

Then you can play a game by

AI > Start Game

and input random seed (non-negative integer).

Convert Tenhou-log to mjai-log

1. Create a directory named 'tenhou_rawlog'
2. download scraw20XX.zip from https://tenhou.net/sc/raw/ and put extracted directory('scraw20XX') in 'tenhou_rawlog' directory
3. Clone and build akochan-reviewer in root directory

    git clone https://github.com/Equim-chan/akochan-reviewer.git
    cd akochan-reviewer
    cargo build

4. Run. Output will be saved in tenhou_mjailog directory.

    python main.py --tenhou_convlog --year 20XX

Dump feature for supervised learning

    python main.py --dump_feature --input_logdir logdir --input_regex log*.json --output_npzdir outdir

Note that system.exe from akochan is required. This command assumes that logfiles log001.json, log002.json, ... are in directory logdir. Output files are saved in directory outdir.

Check supervised model

    python main.py --check_model --log_line XX

Supervised model shows probability of each action at line XX(1-indexed) of log/haifu_log_1001_0.json.

    python main.py --check_model --log_line XX --player_id P

A player P(one of 0,1,2,3), chooses action at line XX of log/haifu_log_1001_0.json.

Input arguments from text file

The argument '--argfile xx.txt' is expanded with the contents of xx.txt. That is, the command

    python main.py --dump_feature --input_logdir logdir --input_regex log*.json --output_npzdir outdir

is equivalent with

    python main.py --dump_feature --argfile xx.txt --output_npzdir outdir

when the contents of xx.txt is the following.

--input_logdir logdir
--input_regex log*.json

Note that '--dump_feature' and '--output_npzdir outdir' can be included in xx.txt.
