Apex (A PyTorch Extension)

This site contains the API documentation for Apex (https://github.com/nvidia/apex), a Pytorch extension with NVIDIA-maintained utilities to streamline mixed precision and distributed training. Some of the code here will be included in upstream Pytorch eventually. The intention of Apex is to make up-to-date utilities available to users as quickly as possible.

Installation instructions can be found here: https://github.com/NVIDIA/apex#quick-start.

Some other useful material, including GTC 2019 and Pytorch DevCon 2019 Slides, can be found here: https://github.com/mcarilli/mixed_precision_references.
