Got this tensorflow error.

Can you update this project.

Can you update this project.

I think the estimator is now depricated.

[Dragjon]

Oh wow, I haven't worked on this for quite a while. Will update it as soon as possible.

Thanks!

Yep the estimator is deprecated from tensorflow 2.16.1 onwards. You can temporarily uninstall and install the older version

pip uninstall tensorflow
pip install tensorflow==2.15.1

From This

Is there any way it can be used on lichess as a UCI engine?

You have to write your own uci parsing protocol, here is a simple example in python

def parse_parameters(line):
    DEFAULT_WTIME = float('inf')
    DEFAULT_BTIME = float('inf')
    parameters = line.split()[1:]
    wtime, btime = DEFAULT_WTIME, DEFAULT_BTIME

    for i in range(len(parameters)):
        if parameters[i] == "infinite":
            wtime = float('inf')
            btime = float('inf')
        elif parameters[i] == "wtime" and i + 1 < len(parameters):
            wtime = float(parameters[i + 1])
        elif parameters[i] == "btime" and i + 1 < len(parameters):
            btime = float(parameters[i + 1])
    return wtime, btime

def play_chess():
    global board, start_time
    remaining_time = 1000000

    while True:
        line = input()
        if line == "uci":
            print("id name My Engine Name")
            print("id author My Name")
            print("uciok")
        elif line == "isready":
            print("readyok")
        elif line.startswith("position startpos"):
            board = chess.Board()
            if "moves" in line:
                _, moves_part = line.split("moves")
                moves = moves_part.strip().split()
                for move in moves:
                    board.push_uci(move)
        elif line.startswith("position fen"):
            _, fen = line.split("fen ")
            fen = fen.split(" ")
            fen = fen[0] + " " + fen[1] + " " + fen[2] + " " + fen[3] + " " + fen[4] + " " + fen[5]
            board.set_fen(fen)
            if "moves" in line:
                _, moves_part = line.split("moves")
                moves = moves_part.strip().split()
                for move in moves:
                    board.push_uci(move)
        elif line.startswith("go"):
            wtime, btime = parse_parameters(line)
            remaining_time = wtime if board.turn == chess.WHITE else btime
            start_time = time.time()
            sb_max_time = remaining_time / sbtm
            hb_max_time = remaining_time / hbtm
            getbestmove()
        elif line == "quit":
            break

• Then you have to build it into an executable, and you can use lichess-bot
• You can refer to the UCI protocol here
