OSError: Can't load tokenizer for 'bert-base-uncased'. If you were trying to load it from 'https://huggingface.co/models', make sure you don't have a local directory with the same name.

首先造成这种错误的原因主要是因为你的服务器没有办法连接huggingface的原因，你可以直接在你的服务器上尝试能否直接ping

ping huggingface.co

那我的机器就是没有数据传输过来，当然前提是你自己的服务器一定要有网络连接（可以尝试ping www.baidu.com来检测自己机器是否有网络）。

解决方案1

使用VPN，这个方法比较适用机器是你自己的，如果机器不是你的，你搭VPN比较麻烦，因为租的服务器会定时清理，在Linux搭建VPN也很简单，大家搜索一哈有很多方案

解决方案2【推荐】

第二种方式适用于租赁的机器的情况，就是直接将本地的下载好（你的本地也需要能访问外网）的预训练模型上传上去，如果你已经在你的本地简单跑过代码了，没有就去官网下载，首先我们确定我们本地文件所处的路径【windows下应该在你的用户文件下面又有个.cache，注意打开隐藏文件夹】：

• 将指定的模型下载到本地【本地机器需要科学上网】

  from transformers import BertModel, BertTokenizer
  
  # 使用bert-large-uncased
  model = BertModel.from_pretrained('bert-large-uncased')
  tokenizer = BertTokenizer.from_pretrained('bert-large-uncased')
  

  此时你的机器上会出现如下图片：
  

• 找到本地下载好的模型文件

  • 如果你是windows用户，你的用户User文件下面又有个.cache/huggingface/hub/，注意打开隐藏文件；
  • 如果你是macos用户在下面地址中

    ~/.cache/huggingface/hub/models--bert-base-uncased
    

• 上传文件到服务器上
  将本地文件上传到服务器的下面地址中

  ~/.cache/huggingface/hub/models--bert-base-uncased
  

  就可以运行你的代码了，但是这里运行的时候有个小问题，就是你运行时候仍然会报错说无法下载这些文件，请耐心等待，你的代码会正常运行
  

  如果你不想出现之前上面还显示出错的问题，那么修改之前的加载方法，之前的加载方法为：

  config = BertConfig.from_pretrained(model_name) 
  

  修改为

  # 指定本地bert模型路径
  bert_model_dir = "/path/to/bert/model" 
  
  config = transformers.BertConfig.from_pretrained(bert_model_dir)
  

  即可
