LEFTeyex / warmup

When instantiating the object WarmUpScheduler and passing e.g. the torch.optim.lr_scheduler.CosineAnnealingLR as in example.py execution fails due to the following error:

Traceback (most recent call last):
  File "test.py", line 26, in <module>
    warmup_scheduler = WarmUpScheduler(optimizer, lr_scheduler,
  File "/Users/tomas.gadea/Desktop/test/env/lib/python3.8/site-packages/warmup_scheduler_pytorch/warmup_module.py", line 52, in __init__
    raise TypeError(f'{type(lr_scheduler).__name__} is not a lr_scheduler in pytorch')
TypeError: CosineAnnealingLR is not a lr_scheduler in pytorch

It does not work for any of the typical torch schedulers.

What is the version of your pytorch？

What is the version of your pytorch？

I have the same error. Torch 2.0.1

@shlyahin I check the code : we need to make add "LRScheduler" in the list of attribute available here :

warmup/src/warmup_scheduler_pytorch/warmup_module.py

Line 51 in f90a352

if not isinstance(lr_scheduler, (_LRScheduler, ReduceLROnPlateau)):

if not isinstance(lr_scheduler, (_LRScheduler, ReduceLROnPlateau)):

if not isinstance(lr_scheduler, (_LRScheduler, LRScheduler, ReduceLROnPlateau)):

but it's for torch 2.0

I will update the code soon to adapt to the new version of PyTorch.
