有人可以帮助我解决需要以下参数的错误吗？

Question

我对 Python 很陌生，我下载了一个代码来帮助我玩纸牌游戏，我修复了一些小错误，但这是我遇到的主要错误。这是错误：

“用法：FFVIII_CardGame_AI2.py [-h] -f FILEPATH -d DEPTH -s STARTING_PLAYER FFVIII_CardGame_AI2.py：错误：需要以下参数：-f、-d、-s"

这是代码部分：

def gamestate_from_file(filepath):
    """
    Generate a GameState object from a file
    """

    with open(filepath) as f:
        dataMap = yaml.safe_load(f)

    gamestate = GameState()
    gamestate.current_player = dataMap["Current_Player"]

    for card_id in dataMap["Cards"]:
        card_details = dataMap["Cards"][card_id]
        card = Card(
            symbol=card_details["symbol"],
            owner=card_details["owner"],
            top=card_details["top"],
            left=card_details["left"],
            right=card_details["right"],
            bottom=card_details["bottom"],
        )
        position = card_details["position"]
        if position == "Hand":
            gamestate.players[card_details["owner"]].hand[card_details["symbol"]] = card
        else:
            gamestate.board[position] = card
    return gamestate


def is_valid_file(parser, arg):
    if not os.path.exists(arg):
        parser.error("The file %s does not exist!" % arg)
    return arg


def parse_args():
    parser = argparse.ArgumentParser()
    parser.add_argument(
        "-f",
        dest="filepath",
        required=True,
        help="Filepath of GameState file (gamestate.yaml)",
        type=lambda x: is_valid_file(parser, x),
    )
    parser.add_argument(
        "-d",
        dest="depth",
        required=True,
        help="Max tree depth of Minimax tree",
        type=int,
    )
    parser.add_argument(
        "-s",
        dest="starting_player",
        required=True,
        type=str,
        help="Starting Player ('P' for Player, or 'O' for Opponent)",
    )
    return parser.parse_args()

任何帮助将不胜感激。

我认为您提供的代码很好，或者至少是我所看到的。也许您可以提供更多详细信息，例如您的命令是什么。因为通常该错误是由于缺少特定的命令行参数导致的
