OSError: We couldn‘t connect to ‘https://huggingface.co‘ to load this file

想折腾bert的同学，应该也遇到这个问题。

一、报错信息分析

完整报错信息：OSError: We couldn't connect to 'https://huggingface.co' to load this file, couldn't find it in the cached files and it looks like google/mt5-small is not the path to a directory containing a file named config.json. Checkout your internet connection or see how to run the library in offline mode at 'https://huggingface.co/docs/transformers/installation#offline-mode'.

OSError 是 Python 中的一个内置异常，在处理文件或目录操作时可能会遇到。OSError 错误通常涉及到文件系统相关的操作，例如创建、读取、写入或删除文件，以及操作目录等。当执行这些操作时，如果出现了错误，就会抛出 OSError 异常。发生这个问题，处理起来就相对麻烦一点，不像ImportError只用下载安装包即可。

We couldn't connect to 'https://huggingface.co' to load this file, couldn't find it in the cached files and it looks like google/mt5-small is not the path to a directory containing a file named config.json.总之huggingface这个网站连不上去不能下载文件，虽然
