I`m beginner.. I'm working with Bert. However, due to the security of the company network, the following code does not receive the bert model directly.

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

So I think I have to download these files and enter the location manually. But I'm new to this, and I'm wondering if it's simple to download a format like .py from github and put it in a location.

I'm currently using the bert model implemented by hugging face's pytorch, and the address of the source file I found is:

https://github.com/huggingface/transformers

Please let me know if the method I thought is correct, and if so, what file to get.

Thanks in advance for the comment.

As described here, what you need to do are download pre_train and configs, then putting them in the same folder. Every model has a pair of links, you might want to take a look at lib code.

For instance

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

with /Users/yourname/workplace/berts/ refer to your folder

Below are what I found

at src/transformers/configuration_bert.py there are a list of models' configs

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

and at src/transformers/modeling_bert.py there are links to pre_trains

  • Thank you very much for the first reply! I've seen that issue when I load the model 1. save them in a directory and rename them respectively config.json and pytorch_model.bin 2. `model = BertModel.from_pretrained('path/to/your/directory')' I used the method of "I downloaded the model of bert-base-multilingual-cased above and it says undefined name."

    after downloading, and moving to your company's folder, during running time, do you have any difficulty?

  • I put the file in the same directory as the file in my jupyter notebook and ran it as follows: 'model = BertModel.from_pretrained ('./')' Can you tell me some examples of code use?

    I see. I added more details, can u check it. I guessed the reason was Bert-base-multilingual-case, there is no class has this name

    depending on what you want. In transformers, the lib provides transforms and fine-tuning on down-stream tasks. These classes are BertModel, BertForPreTraining, BertForMaskedLM, BertForNextSentencePrediction, BertForSequenceClassification, BertForTokenClassification, BertForQuestionAnswering
