我正在嘗試在 python 中使用Poller()帶有兩個(gè)套接字的 ZeroMQ 功能：import zmq# Prepare our context and socketscontext = zmq.Context()receiver = context.socket(zmq.DEALER)receiver.connect("ipc:///tmp/interface-transducer")subscriber = context.socket(zmq.SUB)subscriber.bind("ipc:///tmp/fast-service")subscriber.setsockopt(zmq.SUBSCRIBE, b"10001")# Initialize poll setpoller = zmq.Poller()poller.register(receiver, zmq.POLLIN)poller.register(subscriber, zmq.POLLIN)# Process messages from both socketswhile True:    try:        socks = dict(poller.poll())    except KeyboardInterrupt:        break    if receiver in socks:        message = receiver.recv()        print("RECEIVER OK\n")    if subscriber in socks:        message = subscriber.recv()        print("SUBSCRIBER OK\n")然后發(fā)送消息的服務(wù)器ROUTER描述為：def main():    context = zmq.Context()    router = context.socket(zmq.ROUTER)    router.bind("ipc:///tmp/interface-transducer")    while True:        identity = b'electrode-service'        b_identity = identity        router.send_multipart([b_identity, b'[1,2]'])        print("Sent")        time.sleep(1)if __name__ == "__main__":    main()但是當(dāng)我運(yùn)行這兩個(gè)進(jìn)程時(shí)，它沒有按預(yù)期工作，輪詢器腳本不會(huì)打印任何內(nèi)容。這樣的實(shí)施可能會(huì)出現(xiàn)什么問題？
