Preconfigured Datasets are not available

[vogt31337]

Describe the bug
The step:
"Several preconfigured datasets are available, including most components from the Pile, as well as the Pile train set itself, for straightforward tokenization using the prepare_data.py entry point.

E.G, to download and tokenize the enwik8 dataset with the GPT2 Tokenizer, saving them to ./data you can run:

python prepare_data.py -d ./data

"
creates an Download error. https://data.deepai.org/enwik8.zip is down / not available

To Reproduce
Steps to reproduce the behavior:

1. Fresh install / git clone
2. python prepare_data.py -d ./data

Expected behavior
Getting a dataset.

Proposed solution
Maybe provide another source or another description how to find such a dataset.

Screenshots
If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

• GPUs: 1
• Configs: 20B.yml

wget delivers a certificate issue for data.deepai.org. The certificate has expired.

I open the link through chrome to download

Clicking the link that you say is down downloads it for me as well. Perhaps they had a short outage?
