dataeval.data.Limit¶

class dataeval.data.Limit(size)¶

Cap the dataset to the first size items currently selected.

Applied in place, in pipeline order: Limit truncates whatever selection precedes it, so [Shuffle(), Limit(100)] keeps a random 100 while [Limit(100), Shuffle()] shuffles the first 100. Chaining is allowed — [Limit(1000), Shuffle(), Limit(100)] keeps a random 100 of the first 1000.

Parameters:¶

size : int¶

The maximum size of the dataset.

apply(view)¶

Apply this operation by mutating view in place.

apply_metadata(metadata)¶

Return possibly-updated dataset-level metadata (default: unchanged).
