xCodeEval: A Large Scale Multilingual Multitask Benchmark for Code Understanding, Generation, Translation and Retrieval

We introduce xCodeEval, the largest executable multilingual multitask benchmark to date consisting of 25 M document-level coding examples from about 7.5 K unique problems covering up to 17 programming languages with execution-level parallelism. It features a total of seven tasks involving code understanding, generation, translation and retrieval, and it employs an execution-based evaluation. We develop a test-case based multilingual code execution engine, ExecEval that supports all the programming languages in xCodeEval. We also propose a novel data splitting and a data selection schema for balancing data distributions over multiple attributes based on geometric mean and graph-theoretic principle.

This repository contains the sample code and data link for xCodeEval paper.

Data Download

Currently this repository supports huggingface load_dataset() api. Follow the following example to load dataset for individual examples. 

import datasets

prog_synthesis_dataset = datasets.load_dataset("NTU-NLP-sg/xCodeEval", "program_synthesis")
code_translation_dataset = datasets.load_dataset("NTU-NLP-sg/xCodeEval", "code_translation")
tag_classification_dataset = datasets.load_dataset("NTU-NLP-sg/xCodeEval", "tag_classification")
apr_dataset = datasets.load_dataset("NTU-NLP-sg/xCodeEval", "apr")
pcode_compilation_dataset = datasets.load_dataset("NTU-NLP-sg/xCodeEval", "code_compilation")
retrieval_code_code_dataset = datasets.load_dataset("NTU-NLP-sg/xCodeEval", "retrieval_code_code")
retrieval_nl_code_dataset = datasets.load_dataset("NTU-NLP-sg/xCodeEval", "retrieval_nl_code")
retrieval_corpus_dataset = datasets.load_dataset("NTU-NLP-sg/xCodeEval", "retrieval_corpus")

Hf large data download tricks.

If you are facing long delay with data processing, add a ignore_verifications=True.

prog_synthesis_dataset = datasets.load_dataset("NTU-NLP-sg/xCodeEval", "program_synthesis", ignore_verifications=True)

If you are facing long delay with data downloading, use huggingface streaming mode.

prog_synthesis_dataset = datasets.load_dataset("NTU-NLP-sg/xCodeEval", "program_synthesis", streaming=True)

Just Give me the raw data (😠)

Data can be also downloaded as a git LFS repo from huggingface.

xCodeEval_hf

You can download the full data using the following command.

GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/datasets/NTU-NLP-sg/xCodeEval
cd xCodeEval
git lfs pull

To download a specific part of the dataset, 

GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/datasets/NTU-NLP-sg/xCodeEval
cd xCodeEval
git lfs pull --include "apr/test/*"

We propose 7 Tasks.

  1. Tag Classification
  2. Code Compilation
  3. Program Synthesis
  4. Code Translation
  5. Automatic Program Repair
  6. Code-Code Retrieval
  7. NL-Code Retrieval

Common Data for different tasks

If you are not using huggingface load_dataset() api, you may need to link some data with different tasks.

xCodeEval_fig_1

We have two data files that are required for multiple tasks.

  1. problem_descriptions.jsonl
  2. unittest_db.json

You can find these two files in the root directory of the main branch of huggingface dataset repository. To avoid data redundancy we didn't include these data with the relevant tasks, rather we add a unique id src_uid to retrieve these data.

Structure of problem_descriptions.jsonl

A sample, 

{
    "description": "There are $$$n$$$ positive integers $$$a_1, a_2, \\dots, a_n$$$. For the one move you can choose any even value $$$c$$$ and divide by two all elements that equal $$$c$$$.For example, if $$$a=[6,8,12,6,3,12]$$$ and you choose $$$c=6$$$, and $$$a$$$ is transformed into $$$a=[3,8,12,3,3,12]$$$ after the move.You need to find the minimal number of moves for transforming $$$a$$$ to an array of only odd integers (each element shouldn't be divisible by $$$2$$$).",
    "input_from": "standard input",
    "output_to": "standard output",
    "time_limit": "3 seconds",
    "memory_limit": "256 megabytes",
    "input_spec": "The first line of the input contains one integer $$$t$$$ ($$$1 \\le t \\le 10^4$$$) \u2014 the number of test cases in the input. Then $$$t$$$ test cases follow. The first line of a test case contains $$$n$$$ ($$$1 \\le n \\le 2\\cdot10^5$$$) \u2014 the number of integers in the sequence $$$a$$$. The second line contains positive integers $$$a_1, a_2, \\dots, a_n$$$ ($$$1 \\le a_i \\le 10^9$$$). The sum of $$$n$$$ for all test cases in the input doesn't exceed $$$2\\cdot10^5$$$.",
    "output_spec": "For $$$t$$$ test cases print the answers in the order of test cases in the input. The answer for the test case is the minimal number of moves needed to make all numbers in the test case odd (i.e. not divisible by $$$2$$$).",
    "notes": "NoteIn the first test case of the example, the optimal sequence of moves can be as follows:  before making moves $$$a=[40, 6, 40, 3, 20, 1]$$$;  choose $$$c=6$$$;  now $$$a=[40, 3, 40, 3, 20, 1]$$$;  choose $$$c=40$$$;  now $$$a=[20, 3, 20, 3, 20, 1]$$$;  choose $$$c=20$$$;  now $$$a=[10, 3, 10, 3, 10, 1]$$$;  choose $$$c=10$$$;  now $$$a=[5, 3, 5, 3, 5, 1]$$$ \u2014 all numbers are odd. Thus, all numbers became odd after $$$4$$$ moves. In $$$3$$$ or fewer moves, you cannot make them all odd.",
