重置后可以下numpy和一些其他的了，但是有些库还是报错：
Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.urllib3.conne
ction.HTTPConnection object at 0x00000123181B4470>, 'Connection to pypi.doubanio.com timed out. (connect timeout=15)')': /simple/psutil/

根据你这个报错情况，引起原因一般就是代理设置的问题，所以你可以查看一下是不是有什么软件会更改代理。

如果你只是想要安装第三方库，那么可以去lfd.uci.edu这个上下载Python第三方库进行离线安装。
