Issue: Chapter 6 - Issue Loading `cnn_dailymail` dataset
State: open

### Describe the bug

So I am getting this bug when I try to run cell 4 of the Chapter 6 notebook code:
`dataset = load_dataset("ccdv/cnn_dailymail", version="3.0.0")`

Error Message:
```

Looks like the data is not being loaded. Any advice would be appreciated. Thanks!


### Steps to reproduce the bug

Run all cells of Chapter 6 notebook.
