Sente is an open source python library for the game of Go

sente's Issues

pip installation not working in sente 0.4.3

There seems to be an issue with wheel distribution in sense 0.4.3 that causes pip to be unable to install meson. For the present, please use 0.4.2 until this gets resolved

game.get_sequence() result like on sgf file

game.play(4, 4)
game.play(4, 15)
game.play(15, 15)
print(game.get_sequence())

result

[<sente.Move B[dd]>, <sente.Move W[do]>, <sente.Move B[oo]>]

expected result like on sgf file, more human readable

B[dd];W[do];B[oo]

question
how to achieve it in sente ?

thanks and best regards,

game.get_results() like on sgf file

print('Result :', game.get_results() )

result

Result : <sente.result "W+R">

expected result like on sgf file, more human readable

Result : W+R

question
how to achieve it in sente ?

thanks and best regards,

No such file or directory: 'version.txt'

With Python 3.11, in a Conda environment, I get this:

The file, used by setup.py, is not included within the package served for example here: https://pypi.org/project/sente/#files so to me it seems like this is just a problem of file not being included by accident.

board display option

nice to have another board display option (png, svg, ascii or unicode) like https://pypi.org/project/chess/
or it's already have but not mentioned on the docs

best regards

an example code how to make it a game human vs comp or human vs human

on python module chess https://github.com/niklasf/python-chess, the owner include the link for example how to create their creation useful with a game human vs comp or human vs human
https://jupyter.brynmawr.edu/services/public/dblank/CS371%20Cognitive%20Science/2016-Fall/Programming%20a%20Chess%20Player.ipynb

perhaps sente have another example how to achieve it
tried before base on python chess notebook link above but my problem is when the human player turn input, it's hard to map it into sente move
e.g. using move = input("Move : "), when type 4,4 the machine think it's as string
when separate it
x = int(input("X : ") )
y = int(input("Y : ") )
move = x, y
then it still raise an error

Require Sabaki to jump to a certain node

Awesome package! Thank you so much for implementing sente. Plus, the documentation is clearly written. I'm very excited!

As discussed here, I'm trying to use sente to ask Sabaki to jump to a specific node of a specific sgf file. While sente can serve as an AI (after implementing our own genmove()), I'm certain that it won't be hard to achieve my goal. Would you mind sharing how?

sgf replay can't get game.get_winner()

tested on colab and jupyter (localhost)

def random_player(game):
    move = random.choice(list(game.get_legal_moves() ) )
    return move

def play_game(player1, player2):
    game = sente.Game(9, sente.rules.JAPANESE)
    try:
        while not game.is_over():
            move = random_player(game)
            game.play(move)
            clear_output(wait = True)
            print(game)
    except KeyboardInterrupt:
        msg = "Game interrupted!"
        return (None, msg, game)
    file_sgf = "sgf/sente-random_player.sgf"
    sgf.dump(game, file_sgf)
    print('Winner :', game.get_winner() )

def play_sgf(file_sgf):
    game = sgf.load(file_sgf)
    try:
        for move in game.get_default_sequence():
            game.play(move)
            clear_output(wait = True)
            print(game)
    except KeyboardInterrupt:
        msg = "Game interrupted!"
        return (None, msg, game)
    print('File :', file_sgf)
    print('Winner :', game.get_winner() )

then run to record the game into *.sgf

play_game(random_player, random_player)

result you can see the winner

edit the "sgf/sente-random_player.sgf" using temporary solution on issue/1

and to replay previous game recorded

play_sgf("sgf/sente-random_player.sgf")

result not expected

---------------------------------------------------------------------------

---> 37     print('Winner :', game.get_winner() )
     38 

ValueError: could not get results of game, the game is still ongoing

temporary solution, to get the winner or result is by extract the metadata,
but what's going on,
the function of play_sgf() is to replay the *.sgf file, then expected result is must be same when playing it using play_game() function

best regards

into
;B[df];W[ba];B[fh];W[ch];B[ef];W[cb];B[ad];W[hb];B[ed];W[bg];B[da];W[af];B[be];W[ie];B[ab];W[gi];B[bb];W[bh];B[eg];W[eb];B[hc];W[];B[ei];W[fe];B[dh];W[cg];B[ee];W[cf];B[ic];W[ha];B[bd];W[dd];B[hg];W[fc];B[he];W[hh];B[di];W[ff];B[bf];W[ii];B[gf];W[gg];)

notice on example above, remove the "B" on the last before ")"

[sgf.load] How to handle games with handicap

Hi,
I'm having a little fun coding a SGF to GIF converter.
It works pretty well for now, but I have a problem with handicap games.
When running the code:

...
game = sgf.load(name + ".sgf")
for s in game.get_default_sequence():
        move_sequence = game.get_default_sequence()[:1]
        game.play_sequence(move_sequence)
...

I get this error that pops:

File "C:\Users\olivi\Documents\SGFtoGIF\main.py", line 19, in start
    game.play_sequence(move_sequence)
sente.exceptions.IllegalMoveException: It is not currently white's turn

Am I doing something wrong?
