Issue: loading private custom dataset script - authentication error

### Describe the bug

Train model with my custom dataset stored in HuggingFace and loaded with the loading script requires authentication but I am not sure how ?


I am logged in in the terminal, in the browser. I receive this error: 


/python3.8/site-packages/datasets/utils/file_utils.py", line 566, in get_from_cache
    raise ConnectionError(f"Couldn't reach {url} ({repr(head_error)})")
ConnectionError: Couldn't reach https://huggingface.co/datasets/fkov/s/blob/main/data/s/train/labels `(ConnectionError('Unauthorized for URL `https://huggingface.co/datasets/fkov/s/blob/main/data/s/train/labels. Please use the parameter `**`use_auth_token=True`**` after logging in with `**`huggingface-cli login`**`'))

when I added: `use_auth_token=True` and logged in via terminal then I received error:

or the same error in different format: 
raise ConnectionError(f"`Couldn't reach {url} (error {response.status_code}`)")
ConnectionError: Couldn't reach https://huggingface.co/datasets/fkov/s/blob/main/data/s/train/labels (`error 401`)




### Steps to reproduce the bug

1.  cloned transformers library locally:
https://huggingface.co/docs/transformers/v4.15.0/examples :

> git clone https://github.com/huggingface/transformers
> cd transformers
> pip install .
> cd /transformers/examples/pytorch/audio-classification
> pip install -r requirements.txt

2. created **loading script** 
> https://huggingface.co/docs/datasets/dataset_script  added next to dataset:

3. uploaded **private custom dataset** with loading script to HuggingFace
> https://huggingface.co/docs/datasets/dataset_script

4. added dataset loading script to **local directory** in the above cloned transformers library:
> cd /transformers/examples/pytorch/audio-classification

5. logged in to HuggingFace on local terminal with :
> **huggingface-cli login**

6.  run the model with the custom dataset stored on HuggingFace with code:  https://github.com/huggingface/transformers/blob/main/examples/pytorch/audio-classification/README.md

     cd /transformers/examples/pytorch/audio-classification
>  python run_audio_classification.py \
>     --model_name_or_path facebook/wav2vec2-base \
>     --output_dir l/users/flck/outputs/wav2vec2-base-s \

>     --per_device_eval_batch_size 32 \
>     --dataloader_num_workers 4 \
>     --logging_strategy steps \
>     --logging_steps 10 \
>     --evaluation_strategy epoch \
>     --save_strategy epoch \
>     --load_best_model_at_end True \
>     --metric_for_best_model accuracy \

>     **--use_auth_token=True**  



### Expected behavior

Be able to train a model the https://github.com/huggingface/transformers/blob/main/examples/pytorch/audio-classification/ run_audio_classification.py with private custom dataset stored on HuggingFace.
