Pytorch visdom：不能开始观察

Question

当我运行python -m visdom.server时，它会显示：

for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -3] Temporary failure in name resolution
    logging.error('Error {} while downloading {}'.format(exc.code, key))
AttributeError: 'URLError' object has no attribute 'code'

这是什么意思？我该如何处理？
