# RedPajama & TheStack -- Github Code (refined by Data-Juicer)
A refined version of Github Code dataset in RedPajama & TheStack by [Data-Juicer](https://github.com/alibaba/data-juicer). Removing some "bad" samples from the original dataset to make it higher-quality.
This dataset is usually used to pretrain a Large Language Model.
**Notice**: Here is a small subset for previewing. The whole dataset is available [here](https://dail-wlcb.oss-cn-wulanchabu.aliyuncs.com/LLM_data/our_refined_datasets/pretraining/redpajama-stack-code-refine-result.jsonl) (About 232GB).
## Dataset Information
- Number of samples: 49,279,344 (Keep ~52.09% from the original dataset)
