psutil | psutil-master/CONTRIBUTING.md | Contributing to psutil project
==============================
Issues
------
* The issue tracker is for reporting problems or proposing enhancements related
to the **program code**.
* Please do not open issues **asking for support**. Instead, use the forum at:
https://groups.google.com/g/psutil.
* Before submitting a new issue, **search** if there are existing issues for
the same topic.
* **Be clear** in describing what the problem is and try to be accurate in
editing the default issue **template**. There is a bot which automatically
assigns **labels** based on issue's title and body format. Labels help
keeping the issues properly organized and searchable (by OS, issue type, etc.).
* When reporting a malfunction, consider enabling
[debug mode](https://psutil.readthedocs.io/en/latest/#debug-mode) first.
* To report a **security vulnerability**, use the
[Tidelift security contact](https://tidelift.com/security).
Tidelift will coordinate the fix and the disclosure of the reported problem.
Pull Requests
-------------
* The PR system is for fixing bugs or make enhancements related to the
**program code**.
* If you wish to implement a new feature or add support for a new platform it's
better to **discuss it first**, either on the issue tracker, the forum or via
private email.
* In order to get acquainted with the code base and tooling, take a look at the
**[Development Guide](https://github.com/giampaolo/psutil/blob/master/docs/DEVGUIDE.rst)**.
* If you can, remember to update
[HISTORY.rst](https://github.com/giampaolo/psutil/blob/master/HISTORY.rst)
and [CREDITS](https://github.com/giampaolo/psutil/blob/master/CREDITS) file.

Dataset Card for "AlgorithmicResearchGroup/arxiv_research_code"
Dataset Description
https://huggingface.co/datasets/AlgorithmicResearchGroup/arxiv_research_code
Dataset Summary
ArtifactAI/arxiv_research_code contains over 21.8GB of source code files referenced strictly in ArXiv papers. The dataset serves as a curated dataset for Code LLMs.
How to use it
from datasets import load_dataset
# full dataset (21.8GB of data)
ds = load_dataset("AlgorithmicResearchGroup/arxiv_research_code", split="train")
# dataset streaming (will only download the data as needed)
ds = load_dataset("AlgorithmicResearchGroup/arxiv_research_code", streaming=True, split="train")
for sample in iter(ds): print(sample["code"])
Dataset Structure
Data Instances
Each data instance corresponds to one file. The content of the file is in the code feature, and other features (repo, file, etc.) provide some metadata.
Data Fields
repo(string): code repository name.file(string): file path in the repository.code(string): code within the file.file_length: (integer): number of characters in the file.avg_line_length: (float): the average line-length of the file.max_line_length: (integer): the maximum line-length of the file.extension_type: (string): file extension.
Data Splits
The dataset has no splits and all data is loaded as train split by default.
Dataset Creation
Source Data
Initial Data Collection and Normalization
34,099 active GitHub repository names were extracted from ArXiv papers from its inception through July 21st, 2023 totaling 773G of compressed github repositories.
These repositories were then filtered, and the code from each file was extracted into 4.7 million files.
Who are the source language producers?
The source (code) language producers are users of GitHub that created unique repository
Personal and Sensitive Information
The released dataset may contain sensitive information such as emails, IP addresses, and API/ssh keys that have previously been published to public repositories on GitHub.
