AttributeError: Can't pickle local object 'checkpoint.begin_background..bg_target'

（目前理解）无法将本地对象腌制成二进制格式进行存储，解决方式是把这个函数抽出来作为静态函数，代码如下

# 原代码
@staticmethod
def begin_background(self):
    self.queue = Queue()

    def bg_target(queue):
        while True:
            if not queue.empty():
                filename, tensor = queue.get()
                if filename is None: break
                imageio.imwrite(filename, tensor.numpy())

        self.process = [
            Process(target=bg_target, args=(self.queue,)) \
            for _ in range(self.n_processes)
        ]
        
        for p in self.process: p.start()

# 修改后的代码
    @staticmethod
    def bg_target(queue):
        while True:
            if not queue.empty():
                filename, tensor = queue.get()
                if filename is None: break
                imageio.imwrite(filename, tensor.numpy())

    def begin_background(self):
        self.queue = Queue()

        self.process = [
            Process(target=self.bg_target, args=(self.queue,)) \
            for _ in range(self.n_processes)
        ]
        
        for p in self.process: p.start()
