zeromq（zmq）缺少与C ++发布者和python订阅者的消息

Question

I'm not receiving any zeromq messages when using a python subscriber and a c++ publisher.

I setup a test case with the zguide.
I run taskwork2, taskwork2, tasksink2, taskvent. tasksink2 is a publisher and taskwork2 is a subscriber. When running all c++ or all python parties all works well. When running tasksink2 in c++ and the rest in python, the final KILL message is not received and the taskwork2 tasks never complete.
When running tasksink2 in python and the rest in c++, all works well. Per the missing message guide, I start taskwork2 before tasksink2.

I tried creating simple cases with a c++ publisher sending a test message repeatedly, but python subscribers don't receive any messages.

Any suggestions on a fix or debugging methods?

So far I have only tested this on windows.

Step No.1: Check ZeroMQ version coherence

Test and publish both C++ and Python side ZeroMQ version number outputs

# PYTHON SIDE:
from zmq import zmq_version
zmq_version()
