cannot find model in model name list
Hi , thank you for developing well-made pytorch version of BERT !

I am new to NLP area and have problem while coding like this:
```python
tokenizer = BertTokenizer.from_pretrained('bert-base-uncased')
```

The error discription is below:
```
INFO:pytorch_pretrained_bert.file_utils:https://s3.amazonaws.com/models.huggingface.co/bert/bert-base-uncased-vocab.txt not found in cache, downloading to C:\Users\zxr\AppData\Local\Temp\tmpb3lgzjlo
ERROR:pytorch_pretrained_bert.tokenization:Model name 'bert-base-uncased' was not found in model name list (bert-base-uncased, bert-large-uncased, bert-base-cased, bert-large-cased, bert-base-multilingual-uncased, bert-base-multilingual-cased, bert-base-chinese). We assumed 'https://s3.amazonaws.com/models.huggingface.co/bert/bert-base-uncased-vocab.txt' was a path or url but couldn't find any file associated to this path or url.
```

I searched it and thought it might be poor internet connect.

I downloaded the model i want but donot know how to load it with code.

Thank you very much for your attention!
Hi, could you please provide all the information required in the template so that we may help you? Namely which version of `transformers`, python and PyTorch are you using?

You seem to be using `pytorch-pretrained-BERT`, which is a very old version of this repository. Have you tried using the newer `transformers`, which has much more functionalities and is more robust than `pytorch-pretrained-BERT`?<|||||>I am using `Python 3.6.9` , `torch 1.3.1` and `pytorch-pretrained-bert 0.6.2` .

I am following the tutorial on https://pypi.org/project/pytorch-pretrained-bert/ and meet with this problem.<|||||>I changed to a better Internet and this problem solved .
Sorry for your time and thank you for your attention !<|||||>can u tell me how to change a better internet? i met thie question too<|||||>@zxr19980213
