如何从信号中获取发射数据到python中定义的插槽

如何解决如何从信号中获取发射数据到python中定义的插槽

我正在使用[在此处输入链接描述] [1]链接创建信号并将数据发射到定义的插槽，这是下面的示例代码，

库链接https://pypi.org/project/signalslot/0.0.2/

main.py
---------------
import network 

def __init__(self):
    networkOb = network()
    self.network = self.networkObj.conf_pre_load.connect(self.recvdata)

def recvdata(self,data):
        print("****** main  slot")
        print(data)
        print("==============")

*******************************************

netowrk.py
-----------
import signalslot

def __init__():
  self.conf_pre_load = signalslot.Signal(args="some_data")
  self.readUdpdata()

def readUdpdata():
    while True:
            try:
                data,addr = self.socket_rcv.recvfrom(size)
                self._data = "hello"
                self.conf_pre_load.emit("self._data")
                
            except Exception as e:
                
                print(e)

  

i am getting this error
--------------------------
    raise exceptions.IncompatibleSlotSignature()
signalslot.exceptions.IncompatibleSlotSignature

当网络班级发出数据时，我正试图从主班级内部的插槽中接收数据，自1天以来一直在苦苦挣扎，将不胜感激
