Pull request: yes

# What does this PR do?

The `verbose` arg in `torch.optim.lr_scheduler.LRScheduler` was [removed](https://github.com/pytorch/pytorch/commit/fb1b7ec173a34ae5cccf140e2ad6ed3f05a7892e#diff-036a7470d5307f13c9a6a51c3a65dd014f00ca02f476c545488cd856bea9bcf2L95) in PyTorch 2.7.0, and the corresponding init func of `LayerWiseDummyScheduler` should be updated to avoid Exceptions.
