总结：huggingface不能用，直接设置镜像：
HF_ENDPOINT=https://hf-mirror.com
缘起
随着大家纷纷复工，一些网站又恢复了以前不能用的状态，比如open-webui前几天还能用，现在就报错：

解决方法：
设置环境变量
Windows设置环境变量的方法
找到桌面的“我的电脑”图标，右键，选属性，选择“高级系统设置”，然后点击“环境变量”，就可以修改环境变量了。也可以通过开始菜单的“设置”-“系统”-“关于”--“高级系统设置”，找到“环境变量”设置按钮。
然后加入一个环境变量，名字：HF_ENDPOINT 内容：https://hf-mirror.com
重新开一个控制台终端，启动：

Caching files will still work but in a degraded version that might require more space on your disk. This warning can be disabled by setting the `HF_HUB_DISABLE_SYMLINKS_WARNING` environment variable.

To support symlinks on Windows, you either need to activate Developer Mode or to run Python as an administrator. In order to activate developer mode, see this article: https://docs.microsoft.com/en-us/windows/apps/get-started/enable-your-device-for-development
