π **The GPU-Accelerated Open Source Framework for Efficient Generative AI Model Data Curation** πNeMo Curator is a Python library specifically designed for fast and scalable dataset preparation and curation for generative AI use cases such as foundation language model pretraining, text-to-image model training, domain-adaptive pretraining (DAPT), supervised fine-tuning (SFT) and parameter-efficient fine-tuning (PEFT). It greatly accelerates data curation by leveraging GPUs with [Dask](https://www.dask.org/) and [RAPIDS](https://developer.nvidia.com/rapids), resulting in significant time savings. The library provides a customizable and modular interface, simplifying pipeline expansion and accelerating model convergence through the preparation of high-quality tokens.
## Key Features

## Use NeMo Curator
### Python API Quick ExampleThe following snippet demonstrates how to create a small data curation pipeline that downloads and curates a small subset of the Common Crawl dataset.
```Python
# Download your dataset
dataset = download_common_crawl("/datasets/common_crawl/", "2021-04", "2021-10", url_limit=10)
# Build your pipeline
curation_pipeline = Sequential([
# Fix unicode
Modify(UnicodeReformatter()),
# Discard short records
ScoreFilter(WordCountFilter(min_words=80)),
# Discard low-quality records
ScoreFilter(FastTextQualityFilter(model_path="model.bin")),
# Discard records from the evaluation metrics to prevent test set leakage.
TaskDecontamination([Winogrande(), Squad(), TriviaQA()])
])
# Execute the pipeline on your dataset
curated_dataset = curation_pipeline(dataset)
```### Explore NeMo Curator Tutorials
To get started with NeMo Curator, you can follow the tutorials [available here](https://github.com/NVIDIA/NeMo-Curator/tree/main/tutorials). These tutorials include:
- [`tinystories`](https://github.com/NVIDIA/NeMo-Curator/tree/main/tutorials/tinystories) which focuses on data curation for training LLMs from scratch.
- [`peft-curation`](https://github.com/NVIDIA/NeMo-Curator/tree/main/tutorials/peft-curation) which focuses on data curation for LLM parameter-efficient fine-tuning (PEFT) use-cases.
- [`distributed_data_classification`](https://github.com/NVIDIA/NeMo-Curator/tree/main/tutorials/distributed_data_classification) which focuses on using the domain and quality classifiers to help with data annotation.
- [`single_node_tutorial`](https://github.com/NVIDIA/NeMo-Curator/tree/main/tutorials/single_node_tutorial) which demonstrates an end-to-end data curation pipeline for curating Wikipedia data in Thai.
- [`image-curation`](https://github.com/NVIDIA/NeMo-Curator/blob/main/tutorials/image-curation/image-curation.ipynb) which explores the scalable image curation modules.### Access Python Modules
The NeMo Curator section of the [NeMo Framework User Guide](https://docs.nvidia.com/nemo-framework/user-guide/latest/datacuration/index.html) provides in-depth information about how the Python modules work. The [examples](examples/) directory in the GitHub repository provides scripts that showcase these modules.
### Use CLI Scripts
NeMo Curator also offers CLI scripts for you to use. The scripts in `nemo_curator/scripts` map closely to the supplied Python modules. Refer to the [NeMo Framework User Guide](https://docs.nvidia.com/nemo-framework/user-guide/latest/datacuration/index.html) for more information about the Python modules and scripts.
### Use NeMo Framework Launcher
As an alternative method for interfacing with NeMo Curator, you can use the [NeMo Framework Launcher](https://github.com/NVIDIA/NeMo-Megatron-Launcher). The launcher enables you to easily configure the parameters and cluster. It can also automatically generate the Slurm batch scripts that wrap around the CLI scripts required to run your pipeline.
In addition, other methods are available to run NeMo Curator on Slurm. For example, refer to the example scripts in [`examples/slurm`](examples/slurm/) for information on how to run NeMo Curator on Slurm without the NeMo Framework Launcher.
## Module Ablation and Compute Performance
The modules within NeMo Curator were primarily designed to curate high-quality documents from Common Crawl snapshots in a scalable manner. To evaluate the quality of the curated Common Crawl documents, we conducted a series of ablation experiments. In these experiments, we trained a 357M-parameter GPT-style model using datasets generated at various stages of our data curation pipeline, which was implemented in NeMo Curator.
The following figure shows that the use of different data curation modules implemented in NeMo Curator led to improved model zero-shot downstream task performance.
In terms of scalability and compute performance, using the combination of RAPIDS and Dask fuzzy deduplication enabled us to deduplicate the 1.1 Trillion token Red Pajama dataset in 1.8 hours with 64 NVIDIA A100 Tensor Core GPUs.
Additionally, using the CPU-based modules, the following table shows the time required and resulting data size reduction for each processing step [Common Crawl snapshot from November/December of 2020](https://commoncrawl.org/2020/12/nov-dec-2020-crawl-archive-now-available/) using 30 CPU nodes (with hardware similar to the `c5.24xlarge` [Amazon AWS C5 instance](https://aws.amazon.com/ec2/instance-types/c5/)).
