WebSep 16, 2024 · Explanation: By applying cumsum () row-wise over selectors, we compute for each unmasked element in a the target column number it should be copied to in the output tensor. Then, scatter () performs a row-wise scattering of a 's elements to these computed target locations. WebThe library provides efficient low-precision general matrix multiplication for small batch sizes and support for accuracy-loss minimizing techniques such as row-wise quantization and outlier-aware quantization.
