💻 What is it?
SwallowCode-v1 was a high-quality Python code dataset generated through an LLM-based rewriting pipeline.
However, it had two significant limitations:
(1) it was distributed under the Llama 3.3 Community License, and
(2) its size was limited to… See the full description on the dataset page: https://huggingface.co/datasets/tokyotech-llm/swallow-code-v2.opc-fineweb-code-corpus
OpenCoder Dataset
The OpenCoder dataset is composed of the following datasets:
opc-sft-stage1: the sft data used for opencoder sft-stage1
opc-sft-stage2: the sft data used for opencoder sft-stage2
opc-annealing-corpus: the synthetic data & algorithmic corpus used for opencoder annealing

You can collect those files referring to this metadata and reproduce RefineCode!
Note: Currently, we have uploaded the meta data covered by The Stack V2 (About 50% file volume). Due to complex legal considerations, we are unable to provide the complete source code currently. We are working hard to make the remaining part available.

Cross-domain sequential recommendation dataset
A sequential recommendation dataset drawn from Amazon Reviews 2023, covering
Books, CDs_and_Vinyl, Movies_and_TV, Video_Games.
Each row of interactions.parquet is one user buying or reviewing one item at one time.
Users are sampled so that every one of them is active in all domains, their
interactions are ordered chronologically and cut into train/valid/test, and each
interaction carries a fixed set of 10 candidate items for ranking… See the full description on the dataset page: https://huggingface.co/datasets/sungjin-code/amazon-reviews-for-llm.amazon-reviews-books-for-llm
