This repository contains the code for the RedPajama-V2 dataset. For more information on the dataset, check out our
blog post. The dataset is also available on
HuggingFace. For the code used for the
RedPajama-1T dataset, please refer to the rp_v1 branch in this repo.
RedPajama-V2 is an open dataset for training large language models. The dataset includes over 100B text documents coming from 84 CommonCrawl snapshots and processed using the CCNet pipeline. Out of these, there are 30B documents in the corpus that additionally come with quality signals, and 20B documents that are deduplicated.
The number of documents and tokens for the annotated and deduplicated head_middle part of the dataset is shown in the
table below.
| # Documents | Estimated Token count (deduped) | |
|---|---|---|
| en | 14.5B | 20.5T |
| de | 1.9B | 3.0T |
| fr | 1.6B | 2.7T |
| es | 1.8B | 2.8T |
| it | 0.9B | 1.5T |
| Total | 20.8B | 30.4T |

Copy the file configs/rp_v2.0.conf to e.g. configs/default.conf and configure the environment variables.
These will be used throughout the pipeline.
To run with docker, build the docker image using
. configs/default.conf
cd app
docker build -t "${DOCKER_REPO}:" .
Also, make sure you have s5cmd installed and your S3 profile configured so that you can pull data from an S3 bucket.
You can run the steps of the pipeline without any containerized environment. However, the running scripts assume you have a docker and apptainer installation.
The pipeline is composed of three steps, namely 1) preparing artifacts, 2) computing quality signals, and 3) deduplication.
Important: In case you are not running steps (1) and (2) with the provided scripts (i.e., docker containers built with the provided Dockerfile), make sure to set the PYTHONHASHSEED environment variable to a consistent value (e.g., 42) using
export PYTHONHASHSEED=42This is to ensure consistency of hash functions used in the computation of DSIR weights.
This part of the pipeline creates the artifacts that are used in the subsequent steps. This includes building quality classifiers, training bag-of-ngram generative models for importance weight computation, fetching the list of bad words from the LDNOOBW repo, and fetching the most recent list of blacklisted urls from the UT1 blacklist.
As a first step, download the english wikipedia reference classifier
from here and place it
in ${DATA_ROOT}/wikiref-model/en/en-model.bin. This is the same fasttext classifier that was used in RedPajama-V1.
To create the remaining artifacts, make sure that the environment variables are set in the config file. Then, from the root directory of the repository, run
bash scripts/run_prep_artifacts.sh \
--config configs/rp_v2.0.conf \
--listings /path/to/listings/file.txt\
--max_workers 32where /path/to/listings/file.txt is a file that contains the keys to the ccnet data that you want to process
(e.g., 2023-06/0000/en_head.json.gz).
You can set the max_workers flag to the number of parallel processes you want to use.
This step will generate an id which you can store in the environment variable ARTIFACTS_ID for the next step.
The second step of the pipeline compute the quality signals, including the minhash signatures to run fuzzy deduplication in the subsequent step. To run this step, make sure the environment variables are set in the config file. Then, from the root directory of the repository, run
bash scripts/apptainer_run_quality_signals.sh \
--config configs/rp_v2.0.conf \
--dump_id "2022-49" \
--input_base_uri "file:///path/to/data/root" \
--output_base_uri "file:///path/to/outout/data/root" \
--max_docs -1The third component of the pipeline consists of deduplication steps. Here we provide code to run exact and fuzzy deduplication.
Content based deduplication is implemented in app/src/bloomfilter.py. It can be run independently of the
previous step, but the data needs to stored in an S3 bucket. For this step, from the app directory, run:
python3 app/src/bloomfilter.py \
--listings /path/to/listings/file.txt \
--input_base_uri "s3://path/to/ccnet/data" \
--output_dir "/path/to/output" \
--s3_profile "..." \
--endpoint_url "..." \
--parallel_readers 32 \
--batch_size 10 \
--capacity "..." \
--error_rate "..."It is important to choose the correct capacity (i.e., > #documents), since otherwise the error_rate will not be
guaranteed and more false positives will appear. The implementation is based on the
pybloomfiltermmap3 library.
In the third step of the pipeline, we run locality sensitive hashing on the minhash signatures generated in the first step. To run this step, make sure that you use the same configuration as in the quality signals step. Then, from the root directory of the repository, run
bash scripts/apptainer_run_lsh.sh \
--config configs/rp_v2.0.conf \
--dump_id "2022-49" \
--input_base_uri "file:///path/to/data/root" \
--output_dir "/path/to/output" \
--similarity "<similarity_threshold>" \
--listings "/minhash/listings/file.txt" \
--max_docs -1The implementation is based on polars and was tested with 200M documents on a 64 core machine with 500G of RAM.
The second step of this pipeline computes the following set of quality signals. We hope to grow this list further over time as more signals are developed.
