in jupyter server, can not download huggingface model

[ThumbRocket]

hi
I am using Colab to create a Jupiter server using ngrok.
At this time, when importing the pre-trained huggingface model, infinite loading occurs at the location below.

# Code that is causing the problem
import pandas as pd

from transformers import GPT2Tokenizer, GPT2LMHeadModel, logging as transformers_logging

tokenizer = GPT2Tokenizer.from_pretrained('gpt2')
model = GPT2LMHeadModel.from_pretrained('gpt2')

I think there is a firewall or authentication problem on colab. Please check.

@ThumbRocket Thanks for filing the issue and thanks for using Colab. I tried out the code that you shared and could not reproduce the issue you're facing.

Can you provide a reproducible notebook that exhibits the behavior?
