🛠️ grand-challenge-forge

A utility that generates distributable items that help challenge organizers set up their challenge more easily on Grand-Challenge.org.

Install

Install via PyPi:

pip install grand-challenge-forge
grand-challenge-forge --help

📦 Challenge packs

A challenge pack consists of challenge-tailored examples for the following:

• A script to automate uploading data to an archive
• A submission algorithm that can be submitted to a challenge phase
• An evaluation method that evaluates algorithm submissions and generates performance metrics for ranking

Usage

PACK generation

grand-challenge-forge pack pack-context.json

Will use the context found in pack-context.json and generate a pack at the current working directory in a directory dist/ (default).

Alternatively, you generate a pack by providing a JSON string directly:

grand-challenge-forge pack --output-dir /tmp '{ "challenge": { "slug": "a-slug"...'

This will output a pack directory in the /tmp directory.

Via API pack generation can be done via:

from grand_challenge_forge.forge import generate_challenge_pack
from Pathlib import Path

generate_challenge_pack(
    context={"challenge": {...}}
    output_path=Path("dist/"),
    delete_existing=False,
)

ALGORITHM-TEMPLATE generation

grand-challenge-forge algorithm algorithm-context.json

Will use the context found in algorithm-context.json and generate a algorith-template directory at the current working directory in a directory dist/ (default).

Alternatively, you generate an algorithm template by providing a JSON string directly:

grand-challenge-forge algorithm --output-dir /tmp '{ "algorithm": { ... } }'

This will output an algorithm-template directory in the /tmp directory.

Via API the algorithm-template generation can be done via:

from grand_challenge_forge.forge import generate_algorithm_template
from Pathlib import Path

generate_algorithm_template(
    context={"algorithm": { ... }}
    output_path=Path("dist/"),
    delete_existing=False,
)

🏗️ Development

Install locally

Install grand-challenge-forge locally (requires poetry):

git clone https://github.com/DIAGNijmegen/rse-grand-challenge-forge.git
