WebJul 16, 2024 · As you can see index_select for a dense tensor runs incredibly quickly, but the pytorch index_select is atrociously slow for sparse tensors. However, the algorithm I wrote was several hundred times faster. For the use case I originally built this for it was several thousand times faster! Webtorch — PyTorch 2.0 documentation torch The torch package contains data structures for multi-dimensional tensors and defines mathematical operations over these tensors. Additionally, it provides many utilities for efficient serialization of Tensors and arbitrary types, and other useful utilities.
