Issue: ConnectionError: Couldn't reach https://raw.githubusercontent.com

Hello,
I am trying to run run_glue.py and it gives me this error -

Traceback (most recent call last):

Trying to do python run_glue.py  --model_name_or_path
bert-base-cased
--task_name
mrpc
--do_train
--do_eval
--max_seq_length
128
--per_device_train_batch_size
32
--learning_rate
2e-5
--num_train_epochs

--output_dir

Is this something on my end? From what I can tell, this was re-fixeded by @fullyz a few months ago.
Thank you!


Comments:
the bug code locate in ：
    if data_args.task_name is not None:
        # Downloading and loading a dataset from the hub.
        datasets = load_dataset("glue", data_args.task_name, cache_dir=model_args.cache_dir)

Hi @jinec,

From time to time we get this kind of `ConnectionError` coming from the github.com website: https://raw.githubusercontent.com

Normally, it should work if you wait a little and then retry.

Could you please confirm if the problem persists?

cannot connect，even by Web browser，please check that  there is some  problems。

I can access https://raw.githubusercontent.com/huggingface/datasets/1.7.0/datasets/glue/glue.py without problem...

I can not access https://raw.githubusercontent.com/huggingface/datasets either,   I am in China

Finally i can access it, by the superfast software. Thanks

Excuse me, I have the same problem as you, could you please tell me how to solve it？

It is not related to the area, the ConnectionError with http://raw.githubuserconent.com has persisted with load_data function, datasets module. However, it can be set to either wget  or ssl snippet to  download dataset from github as following. 

`$ wget https://raw.githubusercontent.com/...  --no-check-certificate`


or 

for the tfds, nltk or pandas.read_csv downloading as follows. 

```
import ssl

try:
    _create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
    pass
else:
    ssl._create_default_https_context = _create_unverified_https_context
```

So it is most probably the problem of github rather than users
