是否适合使用产品架构进行服务？(Would it be Appropriate to use the Product Schema for Services?)

 这里的例子是你可以适应和运作的： 
 
 https://docs.python.org/2/library/multiprocessing.html 
 
 您是否使用管理器对象来在进程之间共享内存。 
 
 在您的示例中，您使用管理器创建了一个字典，但是您使用正常字典将其删除 
 
manager = Manager()
d = manager.dict()   # correct
d = dict([(c, 0) for c in C])  # d is not a manager.dict: no shared memory
 
 而是这样做（测试，编译） 
 
d = manager.dict([(c, 0) for c in C])

Example here that you could adapt and which works:
 
https://docs.python.org/2/library/multiprocessing.html
 
You have you use a manager object to be able to share memory between processes.
 
In your example you create a dictionary using the manager but you kill it with a normal dictionary the line after
 
manager = Manager()
d = manager.dict()   # correct
d = dict([(c, 0) for c in C])  # d is not a manager.dict: no shared memory
 
Instead do this (tested, compiles)
 
d = manager.dict([(c, 0) for c in C])
