Can't load a transformer model from huggingface

Question

I was trying to load a transformers model from huggingface to my local jupyter notebook and here's the code

from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("bert-base-cased")

Then it went wrong, and the tracebacks are

OSError: Can't load config for 'bert-base-cased'. 
If you were trying to load it from 'https://huggingface.co/models', 
make sure you don't have a local directory with the same name. 
Otherwise, make sure 'bert-base-cased' is the correct path to a 
directory containing a config.json file 

I'm pretty sure there's no local directory with the same name, how to solve this problem? Or is there any other way to load the model?
