Title: `load_dataset` requires a network connection for local download?
Author: MiroFurtado
State: closed

### Describe the bug

Hi all - I see that in the past a network dependency has been mistakenly introduced into `load_dataset` even for local loads. Is it possible this has happened again?


### Steps to reproduce the bug

```
>>> import datasets
>>> datasets.load_dataset("hh-rlhf")
Repo card metadata block was not found. Setting CardData to empty.
