PyTorch 1.9 was released with major improvements to support scientific computing including torch.linalg, torch.special and Complex Autograd.

The Complex Autograd feature improves testing for complex operators by adding more OpInfos and adding a greater validation through a TorchAudio migration to native complex tensors. 

The new version also includes major improvements to on-device binary size with Mobile Interpreter and native support for elastic-fault tolerance training through the upstreaming of TorchElastic into PyTorch Core.
