我用的Cygwin 的linux 模拟器,python 为3.6,这个运行task_master.py

然后用windows下的命令提示符,运行的task_worker.py,安装的也是Python 3.6.然后修改了ip地址。ip地址可以使用命令提示符,输入ipconfig 查看ip地址。

但如果在命令提示符下运行task_master.py 直接就报错了~

好像是pickle的问题,我在Windows下运行也是报出Can't pickle <function <lambda> at 0x0000000001D43E18>: a ttribute lookup <lambda> on main failed这个错,将callable=lambda: task_queue改成 callable=task_q def task_q(): return task_queue 就ok了

为什么我改了 还是不对,我也是在windows下cmd运行的。 QueueManager.register('get_task_queue', callable=lambda: task_queue) QueueManager.register('get_result_queue', callable=lambda: result_queue) 请问 是这两句都要改吗??
