How to use DDP on Sagemaker using Pytorch Lightning?

[shubhamwagh]

I see that Pytorch Lightning (PL) provides support for multi-node training.
How to use PL trainer to launch multiple Sagemaker instances (nodes) for training? What explicit settings would I need in Sagemaker and PL so as to able to train in DDP fashion.

Thanks.
