像对象这样的字节是必需的，不是字符串错误

Question

这段代码中的错误

errorIndication，errorStatus，errorIndex，varBindNbrTable = cmdGen.nextCmd（cmdgen.CommunityData（comm），                                                                                    cmdgen.UdpTransportTarget（（ip.encode（“ ascii”），161）），                                                                                    '1.3.6.1.2.1.14.10.1.3'）
