报错：导入`transformers`模块时发生了错误

遇见了以下报错

这个报错显示在导入transformers模块时发生了错误，可能是因为缺少了该模块。

为了解决这个问题，需要安装transformers库。可以尝试以下方法：

1. 使用pip安装transformers：

   pip install transformers
   

2. 确保安装的transformers版本与你的代码兼容。你可以指定特定的版本进行安装，例如：

   pip install transformers==4.12.0
   

确保在执行以上步骤之前，你的网络连接正常，并且Anaconda环境或虚拟环境已激活。如果问题仍然存在，请确保你的安装环境和依赖项都正确配置，并尝试进行进一步的故障排除。
