fix: stable fingerprint for closures capturing non-deterministic state
Fixes #7986 When `.map()` uses a closure capturing `self` with non-deterministic state (like UUIDs or loggers), the fingerprint changes every run causing cache misses. Fix: only hash primitive attributes of captured objects instead of the full object. Added a regression test in `tests/test_fingerprint.py`.

fix: pass token_per_repo_id to embed_table_storage when pushing shards
## Summary - Fixes #6348 - When `push_to_hub` is called with a `token`, the per-repo token map (`token_per_repo_id`) is built correctly earlier in the function — but it was never forwarded to `embed_table_storage` during the shard-map step. - This caused a one-line fix: wrap `embed_table_storage` with `functools.parti...

fix(webdataset): when loading data in WebDataset format using load_datasets during multi-matchines training.

GitHub Issues Dataset (huggingface/datasets)

Dataset Description

This dataset contains GitHub issues and pull requests from the huggingface/datasets repository. It was created using the GitHub REST API and processed into a machine-learning-friendly format using the Hugging Face datasets library.

Each record represents either:

  • a GitHub issue, or
  • a pull request (which GitHub treats as a special type of issue)

The dataset includes cleaned metadata fields and derived features to support NLP and machine learning tasks such as classification, summarisation, and exploratory analysis.


Dataset Summary

  • Source: GitHub REST API (huggingface/datasets repository)
  • Format: JSONL
  • Total samples: ~8,000 (issues + pull requests combined)
  • Language: English
  • Created using: Python, Hugging Face datasets, GitHub API

Dataset Fields

Each entry contains the following fields:

  • url: Direct GitHub URL to the issue or pull request
  • number: Issue or PR number
  • title: Title of the issue
  • body: Full text content of the issue
  • state: Issue state (open or closed)
  • created_at: Creation timestamp
  • comments_url: API URL for comments
  • pull_request: If present, indicates the issue is a pull request (otherwise null)
  • is_pull_request: Derived boolean flag (true if pull request, else false)
  • text: Combined field of title + body for NLP tasks

Data Processing Pipeline

The dataset was built using the following steps:

  1. Extracted issues using GitHub REST API
  2. Saved raw responses into JSONL format
  3. Cleaned nested and inconsistent fields
  4. Removed problematic timestamp/nested structures when necessary
  5. Created derived features:
    • is_pull_request
    • text (concatenated title and body)
  6. Loaded using Hugging Face datasets.load_dataset

Intended Uses

This dataset is suitable for:

  • Issue vs pull request classification
  • NLP text classification tasks
  • Summarisation of GitHub issues
  • Repository analytics and insights
  • Learning and experimenting with Hugging Face datasets

Limitations

  • Contains data from only one repository (huggingface/datasets)
  • Includes both issues and pull requests (must be filtered if not needed)
  • Subject to GitHub API rate limits during data collection
  • Text quality varies depending on user input in issues
  • Not representative of all GitHub repositories

Ethical Considerations
