Description

I know that it's possible to define our own custom Differentiable Optimizers and get higher to register them. But I was wondering why optim.AdamW is not supported, since from the doc it appears that optimizers from torch.optim are available out of the box.

Contributor guide

Research direction
Investigate how existing optimizers like Adam are registered in the higher library. Look at the source code to find the registry or list of supported optimizers. Determine if adding AdamW requires simply adding to a list or if there are compatibility issues with the higher order gradient computation.
