本例环境如下：

python版本: 3.7.1

etcd3版本: 0.12.0

报错信息：
state = <grpc._channel._RPCState object at 0x7f51082a8b70>
call = <grpc._cython.cygrpc.SegregatedCall object at 0x7f51080edc08>
with_call = False, deadline = None

    def _end_unary_response_blocking(state, call, with_call, deadline):
        if state.code is grpc.StatusCode.OK:
            if with_call:
                rendezvous = _MultiThreadedRendezvous(state, call, None, deadline)
                return state.response, rendezvous
            else:
                return state.response
        else:
>           raise _InactiveRpcError(state)
E           grpc._channel._InactiveRpcError: <_InactiveRpcError of RPC that terminated with:
E           	status = StatusCode.UNAUTHENTICATED

E           	debug_error_string = "{"created":"@1653981702.899194914","description":"Error received from peer 127.0.0.1:2379","file":"src/core/lib/surface/call.cc","file_line":952,"grpc_message":"Established channel does not have a sufficient security level to transfer call credential.","grpc_status":16}"

本例连接异常是因为grpcio版本太高，grpcio==1.45.0

降级后解决

pip uninstall grpcio

pip install grpcio==1.19.0
