the_pile datasets URL broken. 
Thanks for reporting, @TrentBrick. We are addressing the change with their data host server.

On the meantime, if you would like to work with your fixed local copy of the_pile script, you should use:
```python
load_dataset("path/to/your/local/the_pile/the_pile.py",...
```
instead of just `load_dataset("the_pile",...`.

The latter downloads a copy of `the_pile.py` from our GitHub, caches it locally (inside `~/.cache/huggingface/modules`) and uses that. @TrentBrick, I have checked the URLs and both hosts work, the original (https://the-eye.eu/) and the mirror (https://mystic.the-eye.eu/). See e.g.:
- https://mystic.the-eye.eu/public/AI/pile/
- https://mystic.the-eye.eu/public/AI/pile_preliminary_components/

Please, let me know if you still find any issue loading this dataset by using current server URLs. Great this is working now. Re the download from GitHub... I'm sure thought went into doing this but could it be made more clear maybe here? https://huggingface.co/docs/datasets/installation for example under installing from source? I spent over an hour questioning my sanity as I kept trying to edit this file, uninstall and reinstall the repo, git reset to previous versions of the file etc. Thanks for the quick reply and help too
 Thanks @TrentBrick for the suggestion about improving our docs: we should definitely do this if you find they are not clear enough.

Currently, our docs explain how to load a dataset from a local loading script here: [Load > Local loading script](https://huggingface.co/docs/datasets/loading#local-loading-script)

I've opened an issue here:
- #4732

Feel free to comment on it any additional explanation/suggestion/requirement related to this problem.
https://github.com/huggingface/datasets/pull/3627 changed the Eleuther AI Pile dataset URL from https://the-eye.eu/ to https://mystic.the-eye.eu/ but the latter is now broken and the former works again. 

Note that when I git clone the repo and use `pip install -e .` and then edit the URL back the codebase doesn't seem to use this edit so the mystic URL is also cached somewhere else that I can't find?
