Python 如何将函数作为参数传递给芹菜任务？

我想将函数作为参数传递给芹菜任务。我在stackoverflow（和）中发现了两个类似的问题。我尝试了答案中提到的解决方案，这就是我目前正在做的：

内部呼叫模块：

import marshal

def function_to_be_passed:
    # ...

serialized_func_code = marshal.dumps(function_to_be_passed.__code__)
celery_task.delay(serialized_func_code)

在芹菜任务中，我反序列化并调用函数：

import marshal, types
from celery.task import task

@task()
def celery_task(serialized_func_code):
    code = marshal.loads(serialized_func_code)
    func = types.FunctionType(code, globals(), "some_func_name")

    # calling the deserialized function
    func()

但是，在调用

芹菜任务.delay（序列化函数代码）

时，我得到一个错误：

kombu.exceptions.EncodeError:“utf-8”编解码器无法解码中的字节0xe3 位置0:无效的连续字节

在下面共享堆栈跟踪：

使用pickle提供的

转储

和

加载

时也会出现类似错误

kombu.exceptions.EncodeError:“utf-8”编解码器无法解码中的字节0x80 位置0:起始字节无效

我使用的是Django版本2.2.17和Python版本3.8.5
