Pytorch mixed precision inference
WebMixed precision is enabled in PyTorch by using the Automatic Mixed Precision (AMP), a library from APEX that casts variables to half-precision upon retrieval, while storing variables in single-precision format. Furthermore, to preserve small gradient magnitudes in backpropagation, a loss scaling step must be included when applying gradients. WebJan 28, 2024 · In 2024, NVIDIA released an extension for PyTorch called Apex, which contained AMP (Automatic Mixed Precision) capability. This provided a streamlined solution for using mixed-precision training in PyTorch. In only a few lines of code, training could be moved from FP32 to mixed precision on the GPU. This had two key benefits:
