zeshengzong d7a83ab67b Fix lr_scheduler unexpectedly calls step() when init argument last_epoch is larger than -1 (#149312) ... Fixes #102261 ## Changes - Use flag `_is_initial` to replace `self.last_epoch == 0` condition to judge whether `lr` should be initial value - Add test for `ExponentialLR` checkpoint usecase ## Test Result ```python pytest -s test/optim/test_lrscheduler.py -vv ```  Pull Request resolved: https://github.com/pytorch/pytorch/pull/149312 Approved by: https://github.com/janeyx99 Co-authored-by: Jane (Yuan) Xu <31798555+janeyx99@users.noreply.github.com>		2025-05-22 08:42:37 +00:00
