我正在将一些代码从python 3移植到python 2.7，以便它可以与ROS工具集成，并遇到了pickle thread.lock错误的问题。
在python 3中运行时，一切正常，并且代码的多处理部分没有更改。
这是错误的代码。
from bin.gui.mainWindow_ui import *

SERVER = Server(DATA, LOG)
TAG = "MainWindow"
class MainWindow(QtWidgets.QMainWindow):
"""

def __init__(self):

QtWidgets.QMainWindow.__init__(self)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.running = False

self._enable_ui()
self.ui.textEdit_2.setText(' Not Connected')

self.running = True
LOG.i(TAG, "User clicked CONNECT")
self.listenProcess.start()

一旦我进入self.listenProcess.start（），就会收到以下错误消息
