This PR introduces a new dataset builder, SparseCsv, designed to handle "wide" tabular datasets (e.g., 100k+ columns common in transcriptomics, sparse NLP features, or recommender systems) that are typically too large to load into memory as dense Arrow tables.
It also adds a utility function,
sparse_collate_fn, to seamlessly convert these sparse examples intotorch.sparseorscipy.sparsematrices during training.This PR should fix #7377
