arckit

Python and command-line tools for easily working with the Abstraction & Reasoning Corpus (ARC-AGI, formerly ARC) dataset.

pip install -U arckit

Arckit provides tools for loading the data in a friendly format (without a separate download!), visualizing the data with high-quality vector graphics, and evaluating models on the dataset.

✨ NEW in v0.1: Dataset updated to the latest ARC-AGI and Kaggle datasets with version parameter.

🐍 Python API

Loading the dataset

>>> import arckit
>>> train_set, eval_set = arckit.load_data() # Load ARC1 train/eval

# TaskSets are iterable and indexable
>>> train_set 
<TaskSet: 400 tasks>
>>> train_set[0]
<Task-train 007bbfb7 | 5 train | 1 test>

# Indexing can be done by task ID
>>> train_set[0] == train_set['007bbfb7']
True

# You can load specific tasks by ID
>>> task = arckit.load_single('007bbfb7')

Interacting with tasks

>>> task.dataset
'train'
>>> task.id
'007bbfb7'

## Extracting task Grids
>>> task.train # o task.test
=>  List[Tuple[ndarray, ndarray]] # of input/output pairs

>>> task.train[0][0] # input of 1st train example
array([[0, 7, 7],
       [7, 7, 7],
       [0, 7, 7]])

# Tasks can be previewed (with colour!) in Python.
>>> train_set[15].show()
                                <Task-train 0d3d703e | 4 train | 1 test>

# Get task in original ARC format following fchollet's repo.
>>> task.to_dict()
=>  {
    "id": str,
    "train": List[{"input": List[List[int]], "output": List[List[int]]}],
    "test":  List[{"input": List[List[int]], "output": List[List[int]]}]
    }

Scoring a submission file:

To evaluate a submission in Kaggle ARC format:

>>> eval_set.score_submission(
    'submission.csv', # Submission with two columns output_id,output in Kaggle fomrat
    topn=3,           # How many predictions to consider (default: 3)
    return_correct=False # Whether to return a list of which tasks were solved
    )

Loading a specific dataset version

The ARC-AGI dataset has had several minor bugfixes since original release. By default, the latest version is loaded, but you can specify a version parameter to both load_data and load_single. The version options are:

• latest, arcagi: The latest version of ARC-AGI (also pinned as aa922be)
• kaggle, kaggle2024: The data for the 2024 Kaggle competition
• arc, kaggle2019: The original ARC data, as in the 2019 Kaggle competition

🖼️ Creating visualisations

The arckit.vis submodule provides useful functions for creating vector graphics visualisations of tasks, using the drawsvg module. The docstrings for these functions provide more detailed information as well as additional options.

>>> import arckit.vis as vis
>>> grid = vis.draw_grid(task.train['2013d3e2'][0], xmax=3, ymax=3, padding=.5, label='Example')
>>> vis.output_drawing(grid, "images/grid_example.png") # svg/pdf/png

When drawing tasks, arckit will intelligently resize all of the grids such that the total size of the illustration does not exceed the chosen width/height.

>>> task = vis.draw_task(train_set[0], width=10, height=6, label='Example')
>>> vis.output_drawing(grid, "images/arcshow_example.png") # svg/pdf/png

💻 Command-line tools

arcshow draws a visualisation of a specific task straight to the console:

arcsave saves a visualisation of a specific task to a file (pdf/svg/png), and is useful for inspecting tasks or producing high quality graphics showing specific tasks (e.g. for a paper). Tasks can be specified by their hex ID or by dataset, e.g. train0.

usage: arcsave [-h] [--output OUTPUT] task_id width height

Save a task to a image file.

positional arguments:
  task_id          The task id to save. Can either be a task ID or a string e.g. `train0`
  width            The width of the output image
  height           The height of the output image

optional arguments:
  -h, --help       show this help message and exit
  --output OUTPUT  The output file to save to. Must end in .svg/.pdf/.png. By default, pdf is used.
