PySide2（python）里控件的disconnect()函数要怎么用啊？为什么我每次用都会有RuntimeError啊？

Traceback (most recent call last):
File "C:\Users\hp\Desktop\learn code\GUI\背单词软件\万词斩.py", line 142, in <module>
window = Word()
File "C:\Users\hp\Desktop\learn code\GUI\背单词软件\万词斩.py", line 41, in __init__
self.get_question()

self.connect_()

self.disconnect_()
File "C:\Users\hp\Desktop\learn code\GUI\背单词软件\万词斩.py", line 56, in disconnect_
self.buttons[0].clicked.disconnect(self.b0)
RuntimeError: Failed to disconnect signal clicked().
