GitHub Code Dataset

Dataset Description

The GitHub Code dataset consists of 115M code files from GitHub in 32 programming languages with 60 extensions totaling in 1TB of data. The dataset was created from the public GitHub dataset on Google BiqQuery.

How to use it

The GitHub Code dataset is a very large dataset so for most use cases it is recommended to make use of the streaming API of datasets. You can load and iterate through the dataset with the following two lines of code:

from datasets import load_dataset

ds = load_dataset("codeparrot/github-code", streaming=True, split="train")

 'code': "import mod189 from './mod189';\nvar value=mod189+1;\nexport default value;\n",
 'repo_name': 'MirekSz/webpack-es6-ts',
 'path': 'app/mods/mod190.js',
 'language': 'JavaScript',
 'license': 'isc',
 'size': 73

You can see that besides the code, repo name, and path also the programming language, license, and the size of the file are part of the dataset. You can also filter the dataset for any subset of the 30 included languages (see the full list below) in the dataset. Just pass the list of languages as a list. E.g. if your dream is to build a Codex model for Dockerfiles use the following configuration:

ds = load_dataset("codeparrot/github-code", streaming=True, split="train", languages=["Dockerfile"])

FROM rockyluke/ubuntu:precise

ENV DEBIAN_FRONTEND="noninteractive" \

We also have access to the license of the origin repo of a file so we can filter for licenses in the same way we filtered for languages:

ds = load_dataset("codeparrot/github-code", streaming=True, split="train", licenses=["mit", "isc"])

licenses = []
for element in iter(ds).take(10_000):

Counter({'mit': 9896, 'isc': 104})

Naturally, you can also download the full dataset. Note that this will download ~300GB compressed text data and the uncompressed dataset will take up ~1TB of storage:

ds = load_dataset("codeparrot/github-code", split="train")

Dataset Creation

The dataset was created in two steps:

  1. Files of with the extensions given in the list above were retrieved from the GitHub dataset on BigQuery (full query here). The query was executed on Mar 16, 2022, 6:23:39 PM UTC+1.
  2. Files with lines longer than 1000 characters and duplicates (exact duplicates ignoring whitespaces) were dropped (full preprocessing script here).

Considerations for Using the Data

The dataset consists of source code from a wide range of repositories. As such they can potentially include harmful or biased code as well as sensitive information like passwords or usernames.


You can load any older version of the dataset with the revision argument:

ds = load_dataset("codeparrot/github-code", revision="v1.0")
