**lm-datasets is a collection of datasets for language model training including scripts for downloading, preprocesssing, and sampling.**

The documentation is available [here](https://malteos.github.io/lm-datasets/).

## Quick start

### Installation

Install the `lm-datasets` package with [pip](https://pypi.org/project/lm-datasets/):

```bash
pip install lm-datasets
```

In order to keep the package minimal by default, `lm-datasets` comes with optional dependencies useful for some use cases.
For example, if you want to have the text extraction for all available datasets, run:

```bash
pip install lm-datasets[datasets]
```

### Download and text extraction

To download and extract the plain-text of one or more datasets, run the following command:

```bash
lm_datasets extract_text $DATASET_ID $OUTPUT_DIR
```

By default, output is saved as JSONL files. To change the output format, you can use the `--output_format` argument as below:

```bash
lm_datasets extract_text $DATASET_ID $OUTPUT_DIR --output_format parquet  --output_compression zstd
```

### Available datasets

A list or table with all available datasets can be print with the follow command:

```bash
lm_datasets print_stats --print_output md
```

### Dataset viewer

We provide a Web-based application through streamlit to browse all datasets and their contained text content.
To start the app, first clone this repository, install dependencies, and run the following command:

```bash
# clone is needed since streamlit does not support apps from modules yet
git clone https://github.com/malteos/lm-datasets.git

streamlit run src/lm_datasets/viewer/app.py -- \
    --raw_datasets_dir=$RAW_DATASETS_DIR \
    --output_dir=$PROCESSED_DATASET_DIR
```


## Development & Contributions

### Setup environment

To setup, your local development environment we recommend conda and cloning the repository.
The repository also includes settings and launch scripts for VSCode.

```bash
git clone git@github.com:malteos/lm-datasets.git
cd lm-datasets

conda create -n lm-datasets python=3.10
conda activate lm-datasets

pip install -r requirements.txt
```

Alternatively, you can install the Python package directly from the dev branch:

```bash
pip install git+https://github.com/malteos/lm-datasets.git@dev
```

### Install the pre-commit hooks

This repository uses git hooks to validate code quality and formatting.

```
pre-commit install
git config --bool flake8.strict true  # Makes the commit fail if flake8 reports an error
```

To run the hooks:
```
pre-commit run --all-files
```

### Testing

The tests can be executed with:
```
pytest --doctest-modules --cov-report term --cov=lm_datasets
```
