我正在搁置存储一些数据。

_pickle.PicklingError: Can't pickle <class 'method'>: attribute lookup builtins.method failed


我环顾四周,发现有关未绑定方法的信息可能导致了这种情况,但我在代码中找不到问题。

问题出现在

file['player'] = player


玩家是阶级实体:

player = entity(y,x, '@', 200, False)


这是类实体的代码:

class entity:
def __init__(self, y, x, ch, speed, ai=True):
    self.y = y
    self.x = x
    self.ch = ch
    self.speed = speed
    self.ai = ai


    self.ap = 0
    self.current_action = {'action': self.wait, 'cost': self.speed}
    self.my_turn = False

def draw(self):
    world[self.y][self.x].walkable = False
    gamepad.addch(self.y, self.x, self.ch)

def take_turn(self):

    self.my_turn = True
    cost = self.current_action['cost']
    self.current_action['action']()

    return cost
def move(self, dy, dx):

    if self.my_turn == False:
        self.current_action = {'action': partial(self.move, dy,dx), 'cost':200}
        deck.append(self)

    if self.my_turn == True:

        #p = previous
        py = self.y
        px = self.x


        pt = world[py][px]
        #Paint previous ground tile
        pt.walkable = True
        gamepad.addch(pt.y,pt.x,pt.ch)

        if world[dy][dx].walkable == True:
            self.y = dy
            self.x = dx
            world[dy][dx].walkable = False

        if self.ai == False:
            draw_map(self.y,self.x)


        self.my_turn = False
    return self.y,self.x

def wait(self):
    self.current_action = {'action': self.wait, 'cost': self.speed}
def drunk_move(self):
    dy = self.y + random.randint(-1,1)
    dx = self.x + random.randint(-1,1)
    self.move(dy, dx)
def ai_simple(self):

    #Figure out if player is higher or not:
    wherey = self.y - player.y
    if wherey > 0:
        dy = self.y-1
    else:
        dy = self.y+1

    wherex = self.x - player.x
    if wherex > 0:
        dx = self.x-1
    else:
        dx = self.x+1

    self.move(dy, dx)




在发布此内容之前,我尝试过对pudb进行最后的了解-而且我也遇到了一个错误

file['world'] = world


_

│  File "/usr/lib/python3.3/shelve.py", line 124, in                    │
│__setitem__                                                            │
│    p.dump(value)                                                      │
│_pickle.PicklingError: Can't pickle <class                             │
│'__main__.tile'>: attribute lookup __main__.tile failed                │


(在没有pudb的情况下运行代码时不会显示)

这是世界:

world = [[ tile(yy,xx,True,'.')
    for xx in range(WORLD_WIDTH) ]
        for yy in range(WORLD_HEIGHT) ]


这是类磁贴:

class tile:
def __init__(self,y,x,walkable,ch):
    self.x = x
    self.y = y
    self.walkable = walkable
    self.ch = ch


最后,这是调用shelve的完整功能:

def save_game():
    file = shelve.open('savegame', 'n')
    file['world'] = world
    file['player']= player

    file.close()


我相信这就是所有相关的代码。

是什么导致这些错误?

最佳答案

第一个问题是由您的实体类中的这一行引起的:

self.current_action = {'action': self.wait, 'cost': self.speed}


current_action包含对绑定方法的引用,这些方法不能被腌制。您可以使用__getstate____setstate__来改变您的酸洗行为,因此您无需酸洗该方法,而是在酸洗时使用其名称(或在已分配partial对象的情况下使用名称和自变量),并进行恢复酸洗时间的值。

我不确定您的第二个问题,但是如果仅在调试器中运行它时才发生,那么调试器如何加载__main__模块可能是一个问题。您可以尝试将__main__块移动到另一个模块中,然后从那里导入和扩展代码。有时可以解决此类问题。
