成功解决ForkingPickler(file, protocol).dump(obj) TypeError: can't pickle Environment objects

---

解决问题

ForkingPickler(file, protocol).dump(obj)
TypeError: can't pickle Environment objects

解决思路

类型错误:无法pickle环境对象

解决方法(三种)

T1、将队列移动到self，而不是作为函数包和send的参数。

参考国外网友解释：TypeError: can't pickle _thread.lock objects

T2、multiprocessing.Manager().Queue() instead of multiprocessing.Queue
参考国外网友解释：multiprocessing.Pool - PicklingError: Can't pickle <type 'thread.lock'>: attribute lookup thread.lock failed

T3、寻求更好的办法ing
