Unable to download PUBMED_title_abstracts_2019_baseline.jsonl.zst

description: A bug in a dataset script provided in the library
name: dataset bug

## Describe the bug
I am unable to download the PubMed dataset from the link provided in the [Hugging Face Course (Chapter 5 Section 4)](https://huggingface.co/course/chapter5/4?fw=pt).

https://the-eye.eu/public/AI/pile_preliminary_components/PUBMED_title_abstracts_2019_baseline.jsonl.zst 

## Steps to reproduce the bug
```python
# Sample code to reproduce the bug
from datasets import load_dataset

# This takes a few minutes to run, so go grab a tea or coffee while you wait :)
data_files = "https://the-eye.eu/public/AI/pile_preliminary_components/PUBMED_title_abstracts_2019_baseline.jsonl.zst"
pubmed_dataset = load_dataset("json", data_files=data_files, split="train")
pubmed_dataset
```

I also tried with `wget` as follows.
```
wget https://the-eye.eu/public/AI/pile_preliminary_components/PUBMED_title_abstracts_2019_baseline.jsonl.zst
```

## Expected results
I expect to be able to download this file.

## Actual results
Traceback
```

Comments:
Hi @ToddMorrill, thanks for reporting.

Three weeks ago I contacted the team who created the Pile dataset to report this issue with their data host server: https://the-eye.eu

They told me that unfortunately, the-eye was heavily affected by the recent tornado catastrophe in the US. They hope to have their data back online asap.

Hi @ToddMorrill, people from the Pile team have mirrored their data in a new host server: https://mystic.the-eye.eu

See:
- #3627

It should work if you update your URL.

We should also update the URL in our course material.

The old URL is still present in the HuggingFace course here: 
https://huggingface.co/course/chapter5/4?fw=pt

I have created a PR for the Notebook here: https://github.com/huggingface/notebooks/pull/148
Not sure if the HTML is in a public repo. I wasn't able to find it. 

Fixed the other two URLs here: 
https://github.com/mwunderlich/notebooks/pull/1

Both URLs are broken now
`HTTPError: 404 Client Error: Not Found for URL: https://the-eye.eu/public/AI/pile_preliminary_components/PUBMED_title_abstracts_2019_baseline.jsonl.zst`
And
`ConnectTimeout: HTTPSConnectionPool(host='mystic.the-eye.eu', port=443): Max retries exceeded with url: /public/AI/pile_preliminary_components/PUBMED_title_abstracts_2019_baseline.jsonl.zst (Caused by ConnectTimeoutError(, 'Connection to mystic.the-eye.eu timed out. (connect timeout=10.0)'))`




I was able to find a torrent with "The Pile" dataset here: [The Pile An 800GB Dataset of Diverse Text for Language Modeling ](https://academictorrents.com/details/0d366035664fdf51cfbe9f733953ba325776e667)

The complete dataset is huge, so I would suggest you to download only the "PUBMED_title_abstracts_2019_baseline.jsonl.zst" file, which is about 7GB. You can do this by using a torrent client of your choice (I typically utilize Transmission, which is pre-installed in Ubuntu distributions).

any suggestions?

this seems to work but it's rather annoying.

Summary of how to make it work:
1. get urls to parquet files into a list
2. load list to load_dataset via `load_dataset('parquet', data_files=urls)` (note api names to hf are really confusing sometimes)
3. then it should work, print a batch of text.

presudo code
```python
urls_hacker_news = [
    "https://huggingface.co/datasets/EleutherAI/pile/resolve/refs%2Fconvert%2Fparquet/hacker_news/pile-train-00000-of-00004.parquet",
    "https://huggingface.co/datasets/EleutherAI/pile/resolve/refs%2Fconvert%2Fparquet/hacker_news/pile-train-00001-of-00004.parquet",
    "https://huggingface.co/datasets/EleutherAI/pile/resolve/refs%2Fconvert%2Fparquet/hacker_news/pile-train-00002-of-00004.parquet",
    "https://huggingface.co/datasets/EleutherAI/pile/resolve/refs%2Fconvert%2Fparquet/hacker_news/pile-train-00003-of-00004.parquet"

If some people stumble upon this thread and still have this problem, i reuploaded the dataset to HF [here](https://huggingface.co/datasets/casinca/PUBMED_title_abstracts_2019_baseline)

Its the exact same dataset you just have to change the url from the course, for example:

```python
from datasets import load_dataset, DownloadConfig

data_files = "https://huggingface.co/datasets/casinca/PUBMED_title_abstracts_2019_baseline/resolve/main/PUBMED_title_abstracts_2019_baseline.jsonl.zst"
pubmed_dataset = load_dataset(
    "json",
    data_files=data_files,
    split="train",
    download_config=DownloadConfig(delete_extracted=True),  # optional argument
)
```
