FAIR Universe - NeurIPS 2025 Weak Lensing Uncertainty Challenge

This dataset is a HF mirror of the official challenge training data for this challenge:

https://www.codabench.org/competitions/8934/

No further processing has been applied to it, it is purely intended to simplify access to the challenge.

To get started:

import datasets

dset = datasets.load_dataset("eiffl/neurips-wl-challenge")
dset = dset.with_format('jax')

example = dset['train'][0]
