class lightning_ir.retrieve.pytorch.sparse_searcher.TorchSparseSearcher(index_dir: Path, search_config: TorchSparseSearchConfig, module: BiEncoderModule, use_gpu: bool = True)[source]

Bases: ExactSearcher

Torch-based sparse searcher for Lightning IR framework.

__init__(index_dir: Path, search_config: TorchSparseSearchConfig, module: BiEncoderModule, use_gpu: bool = True) → None[source]

Initialize the TorchSparseSearcher.

Parameters:

  • index_dir (Path) – Directory containing the index files.

  • search_config (TorchSparseSearchConfig) – Configuration for the searcher.

  • module (BiEncoderModule) – The BiEncoder module to use for scoring.

  • use_gpu (bool) – Whether to use GPU for computations. Defaults to True.

Methods

__init__(index_dir, search_config, module[, ...])

Initialize the TorchSparseSearcher.

to_gpu()

Move the searcher and index to GPU if available.

Attributes

to_gpu() → None[source]
