problem when loading local model
I have problem when I use

`PRE_TRAINED_MODEL_NAME = './chinese-roberta-wwm-ext'
tokenizer = BertTokenizer.from_pretrained(PRE_TRAINED_MODEL_NAME)`

and put the model on "'./chinese-roberta-wwm-ext" directory, it still download another new model in "/.cache" but not my local model. And every time I run it I have to wait for a long time.
 info shows

sometimes it shows
