## 1.问题 ##

**pip下载出问题**，尝试网上的各种方法如这个高赞文章：[https://blog.csdn.net/lsf\_007/article/details/87931823][https_blog.csdn.net_lsf_007_article_details_87931823]

**apt-get update更新用不了 **

不抱希望的试了下。直接输入以下解决：

echo "nameserver 8.8.8.8" | tee /etc/resolv.conf > /dev/null

**pip安装正常 **

pip install -i https://mirrors.aliyun.com/pypi/simple hpbandster ConfigSpace hyperopt

## 3.建议 ##

对于网上要改什么proxy的，慎重！！！这么点事，整了几个小时，对网络不懂，真是能把自己坑成傻子！
