ConnectionError: Couldn't reach dataset_infos.json 
Unfortunately, I can't reproduce the error. What does the following code return for you?
```python
import requests
from huggingface_hub import hf_hub_url
r = requests.get(hf_hub_url("codeparrot/codeparrot-clean-train", "dataset_infos.json", repo_type="dataset"))
```

Also, can you provide more info about your network (region, proxies, etc.)?
