|
| | This dataset consists of meta information (including the repository name and file path) of the raw code data from **RefineCode**. 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.* |

| | **RefineCode** is a **high-quality**, **reproducible** code pretraining corpus comprising **960 billion** tokens across **607** programming languages and **75 billion** code-related token recalled from web corpus, incorporating over **130** language-specific rules with customized weight assignments. |
| | Our dataset shows better training efficacy and efficiency compared with the training subset of The Stack V2. |

|
| | We also use PCA to visualize the embeddings extracted from CodeBERT for The Stack V2 and **RefineCode**, showing a clear advance of our pretraining dataset. |
