NNI启动失败, 提示ERROR: Restful server start failed!
首先确定系统
如为Linux，尝试以下方法
可能是网络配置有问题。可检查以下问题。
可能需要链接 127.0.0.1 与 localhost。 在 /etc/hosts 中增加 127.0.0.1 localhost。
也可能设置了一些代理。检查环境中是否有如 HTTP_PROXY 或 HTTPS_PROXY 的变量，如果有，则需要取消。
如为Windows，尝试以下方法
pip list
确定nni版本，在2.4中有bug导致restful服务器启动失败，该bug已在2.5版本中被修复
故：
回退2.3版本
python -m pip install --upgrade nni==2.3
或者在GitHub中下载最新的2.5版本并安装
异常栈：
