CodeContests

CodeContests is a competitive programming dataset for machine-learning. This dataset was used when training AlphaCode.

It consists of programming problems, from a variety of sources:

Site	URL	Source
Aizu	https://judge.u-aizu.ac.jp	CodeNet
AtCoder	https://atcoder.jp	CodeNet
CodeChef	https://www.codechef.com	description2code
Codeforces	https://codeforces.com	description2code and Codeforces
HackerEarth	https://www.hackerearth.com	description2code

Problems include test cases in the form of paired inputs and outputs, as well as both correct and incorrect human solutions in a variety of languages.

Usage

Install the Cloud SDK, which provides the gsutil utility. You can then download the full data (~3GiB) with, e.g:

gsutil -m cp -r gs://dm-code_contests /tmp

The data consists of ContestProblem protocol buffers in Riegeli format. See contest_problem.proto for the protocol buffer definition and documentation of its fields.

The dataset contains three splits:

Split	Filename
Training	`code_contests_train.riegeli-*-of-00128`
Validation	`code_contests_valid.riegeli`
Test	`code_contests_test.riegeli`

There is example code for iterating over the dataset in C++ (in print_names.cc) and Python (in print_names_and_sources.py). For example, you can print the source and name of each problem in the validation data by installing bazel and then running:

bazel run -c opt \
  :print_names_and_sources /tmp/dm-code_contests/code_contests_valid.riegeli

Or do the same for the training data with the following command (which will print around 13000 lines of output):

bazel run -c opt \
  :print_names_and_sources /tmp/dm-code_contests/code_contests_train.riegeli*

Planned updates

We plan to update this repository with code for executing and evaluating potential solutions.
