websocket - 无法在 google colab 上分配请求的地址

Question

我在 colab 笔记本上遇到以下错误：

import syft as sy
from syft.workers.node_client import NodeClient
import torch
hook = sy.TorchHook(torch)
nodes = ["ws://localhost:3000/","ws://localhost:3001/"]
compute_nodes = []
for node in nodes:
    compute_nodes.append( NodeClient(hook, node) )

实际上是在NodeClient使用函数和类，例如self.connect(), self.ws = websocket.create_connection(**args), websock.settimeout(timeout if timeout is not None else getdefaulttimeout()), websock.connect(url, **options), self.sock_opt.timeout = options.get('timeout', self.sock_opt.timeout), self.sock, addrs = connect(url, self.sock_opt, proxy_info(**options),options.pop('socket', None)), sock = _open_socket(addrinfo_list, options.sockopt, options.timeout), 和sock.connect(address).

但它会产生错误： OSError: [Errno 99] Cannot assign requested address。
