The Pile Replication Code
The official website for the the Pile is here.
The Pile is a large, diverse, open source language modelling data set that consists of many smaller datasets combined together. The objective is to obtain text from as many modalities as possible to ensure that models trained using The Pile will have much broader generalization abilities.
This repository is for replicating or making variants of the Pile. IF YOU ARE HERE TO USE THE PILE DATASET, THIS REPO IS PROBABLY NOT WHAT YOU ARE LOOKING FOR. A copy of the Pile can be downloaded here.

Usage
Install:
pip install -e .
To replicate pile
python the_pile/pile.py --interleave_output 30 --using pile_reprod
Use the pass 2 script here to complete shuffling.
Other
To force download all data:
python the_pile/pile.py --force_download
To generate fasttext training data for CC filtering (OWT2 only):
sudo apt install build-essential
python the_pile/pile.py --using owt2 --make_fasttext

Workflow
To propose a new dataset be added to the Pile, open an issue. Your issue should include a description of the dataset, its size, what language(s) it is in, a link to the data, and any other relevant information. If a project manger approves your proposal, they will change its label to 
To claim responsibility for implementing an unclaimed dataset, leave a comment on one of our unassigned issues. Once an dataset has been assigned to you, make the necessary changes to datsets.py and pile.py in a fork and submit a pull request. If you require, you can also submit a script for processing the data as shown here.
To raise an issue that is not proposing a new dataset, open an issue with the tag 
Data ready for final implementation should meet the following criteria:
- The data must be in lm_dataformat format.
- The data must be shuffled.
In preparation for the initial release, we are no longer accepting additions to the master branch. If you would like to contribute a dataset, please submit the pull request to the Version2 branch.
