# BigDL-Nano PyTorch Overview

BigDL-Nano can be used to accelerate PyTorch or PyTorch-Lightning applications on both training and inference workloads. The optimizations in BigDL-Nano are delivered through a extended version of PyTorch-Lightning `Trainer`. These optimizations are either enabled by default, or can be easily turned on by setting a parameter or calling a method.
