我是初学者..我正在和伯特一起工作。但是由于公司网络的安全问题，下面的代码并没有直接接收到bert模型。

tokenizer = BertTokenizer.from_pretrained('bert-base-multilingual-cased', do_lower_case=False)
model = BertForSequenceClassification.from_pretrained("bert-base-multilingual-cased", num_labels=2)

所以我想我必须下载这些文件并手动输入位置。但我是新手，我想知道从 github 下载 .py 之类的格式并将其放在某个位置是否简单。

我目前使用的是抱脸的pytorch实现的bert模型，找到的源文件地址是：

https://github.com/huggingface/transformers

请让我知道我认为的方法是否正确，如果正确，要获取什么文件。

提前感谢您的评论。

如此处所述，您需要做的是下载pre_train，configs然后将它们放在同一个文件夹中。每个模型都有一对链接，你可能想看看 lib 代码。

例如

import torch
from transformers import *
model = BertModel.from_pretrained('/Users/yourname/workplace/berts/')

/Users/yourname/workplace/berts/参考您的文件夹

以下是我发现的

在src/transformers/configuration_bert.py有一个模型的配置列表

BERT_PRETRAINED_CONFIG_ARCHIVE_MAP = {
    "bert-base-uncased": "https://s3.amazonaws.com/models.huggingface.co/bert/bert-base-uncased-config.json",

}

并且src/transformers/modeling_bert.py有指向 pre_trains 的链接
