我最近一直在使用python学习GNU Radio，并且在制作ASCII来浮动符号分层块调制时，我遇到了这个错误：
Qt GUI: Could not restore geometry: restoreGeometry(self, geometry: Union[QByteArray, bytes, bytearray]): argument 1 has unexpected type 'NoneType'
Traceback (most recent call last):
File "C:\Users\alper\Documents\GNU Radio\asc2sym_bf.py", line 201, in <module>

TypeError: __init__(): incompatible constructor arguments. The following argument types are supported:

我尝试调试它，但没有成功:(，所以请帮助我，这是我写的代码：

我很确定代码是正确的，但无法理解错误。
有人可以帮助我吗？
您使用
1您必须使用两个有效值之一：
gr.endianess_t.GR_MSB_FIRST….GR_LSB_FIRST
