```
from datasets import load_dataset, concatenate_datasets
bookcorpus = load_dataset("bookcorpus", split="train")
openweb = load_dataset("openwebtext", split="train")
cc_news = load_dataset("cc_news", split="train")
cc_news = cc_news.remove_columns([col for col in cc_news.column_names if col != "text"])
cc_stories = load_dataset("spacemanidol/cc-stories", split="train")
return concatenate_datasets([bookcorpus, openweb, cc_news, cc_stories['train']])
```
