Can not find vocabulary file for Chinese model
After I convert the TF model to pytorch model, I run a classification task on a new Chinese dataset, but get this:

CUDA_VISIBLE_DEVICES=3 python run_classifier.py   --task_name weibo --do_eval --do_train --bert_model chinese_L-12_H-768_A-12 --max_seq_length 128   --train_batch_size 32   --learning_rate 2e-5   --num_train_epochs 3.0   --output_dir bert_result

need to specify the path of vocab.txt for:
tokenizer = BertTokenizer.from_pretrained(args.bert_model)<|||||>@zlinao ，i try to load the vocab using the following code：
tokenizer = BertTokenizer.from_pretrained("bert-base-chinese//vocab.txt"

however，get errors

do you have the same problem？<|||||>Hi,
Why don't you guys just do `tokenizer = BertTokenizer.from_pretrained('bert-base-chinese')` as [indicated in the readme](https://github.com/huggingface/pytorch-pretrained-BERT#loading-google-ais-pre-trained-weigths-and-pytorch-dump) and the `run_classifier.py` example?<|||||>> Hi,

Yes, it is easier to use shortcut name. Thanks for your great work.<|||||>> @zlinao ，i try to load the vocab using the following code：

you can change you encoding to 'utf-8' when you load the vocab.txt
