Why do we need getattr here, does the diffusion_model.model sometimes not have a module? Or is this connected to the torch change?

It seems that diffusion_model.model only has module when it's in the nn.parallel.DistributedDataParallel container, so this getattr accounts for when model = diffusion_model.model.

If there's a better way to account for this (e.g. just adding the module attribute to the model instance if it's missing), please let me know and I can make the change!

Small tweaks to train_parallel.py (and related changes to distributed.py and generate_batch.py) so that it works on a single machine. Mainly, it now only uses the nn.parallel.DistributedDataParallel model container if in a distributed environment.
