我在使用python库连接到GO中运行的grpc服务时遇到问题
我正在使用图书馆
grpcio==1.10.1
这是我的代码
import grpc
from hello_world import hello_world_pb2_grpc
from hello_world import hello_world_pb2
channel = grpc.insecure_channel('localhost:5000')
stub =hello_world_pb2_grpc.CallStub(channel)
stub.Call()
我在执行
时设置调试模式后出现以下错误channel = grpc.insecure_channel('localhost:5000')

这就是错误的样子

显示它无法连接到给定端口的给定服务。但是，其他服务可以连接到给定端口，用其他语言编写。
此外，如果我执行telnet localhost:5000，则可以连接
任何想法可能是什么问题？
