Please change file /apollo/cyber/python/cyber_py3/cyber.py, line 365 to

return _CYBER.PyChannelUtils_get_debugstring_by_msgtype_rawmsgdata(str(str(msg_type)[2:-1]), rawmsgdata)

Based on @hackerliang's advice, I change file /apollo/cyber/python/cyber_py3/cyber.py, line 365 to

temp_byte = _CYBER.PyChannelUtils_get_debugstring_by_msgtype_rawmsgdata(msg_type.decode('utf-8'), rawmsgdata)
return temp_byte.decode('utf-8')

which turns the bytes string into a str type and solves this problem.
