TACO Dataset

TACO is a benchmark for code generation with 26443 problems. It can be used to evaluate the ability of language models to generate code from natural language specifications.

Key Update:

We remove and modified some test cases in test set. Please update to use the newest version.

Languages

The dataset contains questions in English and code solutions in Python.

How to use it

You can load and iterate through the dataset with the following two lines of code for the train split:

from datasets import load_dataset
import json

ds = load_dataset("BAAI/TACO", split="train")
sample = next(iter(ds))
# non-empty solutions and input_output features can be parsed from text format this way:
sample["solutions"] = json.loads(sample["solutions"])
sample["input_output"] = json.loads(sample["input_output"])
sample["raw_tags"] = eval(sample["raw_tags"])
sample["tags"] = eval(sample["tags"])
sample["skill_types"] = eval(sample["skill_types"])
print(sample)

Each sample consists of a programming problem formulation in English, some ground truth Python solutions, test cases that are defined by their inputs and outputs and function name if provided, as well as some metadata regarding the difficulty level (difficulty), topics of task (raw tags), algorithms (tags) as well as required programming skill types (skill_types) of the problem and its source.

If a sample has non empty input_output feature, you can read it as a dictionary with keys inputs and outputs and fn_name if it exists, and similarily you can parse the solutions into a list of solutions as shown in the code above.

You can also filter the dataset for the difficulty level: EASY, MEDIUM, MEDIUM_HARD, HARD and VERY_HARD, or filter the programming skill types: Amortized analysis, Bit manipulation, Complete search, Data structures, Dynamic programming, Greedy algorithms, Range queries, Sorting. Just pass the list of difficulties or skills as a list. E.g. if you want the most challenging problems, you need to select the VERY_HARD level:

ds = load_dataset("BAAI/TACO", split="train", difficulties=["VERY_HARD"])
print(next(iter(ds))["question"])

#OUTPUT:
"""Let S(n) denote the number that represents the digits of n in sorted order. For example, S(1) = 1, S(5) = 5, S(50394) = 3459, S(353535) = 333555.
Given a number X, compute <image> modulo 109 + 7.

Input
The first line of input will contain the integer X (1 ≤ X ≤ 10700).

Output
Print a single integer, the answer to the question.

Examples

Input
21

Output
195

Input
345342

Output
390548434

Note

The first few values of S are 1, 2, 3, 4, 5, 6, 7, 8, 9, 1, 11, 12, 13, 14, 15, 16, 17, 18, 19, 2, 12. The sum of these values is 195.

Or if you want the problems invovled with Range queries and Sorting, you need to select the skills Range queries and Sorting:

ds = load_dataset("BAAI/TACO", split="train", skills=["Range queries", "Sorting"])
