Motivation

Fix torch Future Warning:
FutureWarning: torch.cuda.amp.GradScaler(args...) is deprecated. Please use torch.amp.GradScaler('cuda', args...) instead.

Modification

Deprecate torch.cuda.amp and transfer to torch.amp, and partial it with device='cuda'. The modification will not introduce any influence on the following codes in this file

FutureWarning: `torch.cuda.amp.GradScaler(args...)` is deprecated. Please use `torch.amp.GradScaler('cuda', args...)` instead.

Motivation

When using torch.compile, the 'disable' key compile could override the compile. When disable is set to True, there should be no prompt like 'The model has been compiled'.

Modification

Add a simple check when compile is a dict, and check if there exists a key 'disable'.

FSDP.optim_state_dict_to_load requires the following parameters:

model: Module,
optim: Optimizer,
optim_state_dict: Dict[str, Any]
