|
||

||
- `Trainer.logged_metrics` now always contains scalar tensors, even when a Python scalar was logged ([#11270](https://github.com/PyTorchLightning/pytorch-lightning/pull/11270))
|
||
- The tuner now uses the checkpoint connector to copy and restore its state ([#11518](https://github.com/PyTorchLightning/pytorch-lightning/pull/11518))

|
||

|
||
- The `trainer.global_step` value is now increased right after the `optimizer.step()` call which will impact users who access it during an intra-training validation hook ([#11805](https://github.com/PyTorchLightning/pytorch-lightning/pull/11805))
|
||
- The filename of checkpoints created with `ModelCheckpoint(filename='{step}')` is different compared to previous versions. A checkpoint saved after 1 step will be named `step=1.ckpt` instead of `step=0.ckpt` ([#11805](https://github.com/PyTorchLightning/pytorch-lightning/pull/11805))
|
||

|
||
- When using DP (data-parallel), Lightning will no longer automatically reduce all tensors returned in training_step; it will only reduce the loss unless `training_step_end` is overridden ([#11594](https://github.com/PyTorchLightning/pytorch-lightning/pull/11594))
|
||
- When using DP (data-parallel), the `training_epoch_end` hook will no longer receive reduced outputs from `training_step` and instead get the full tensor of results from all GPUs ([#11594](https://github.com/PyTorchLightning/pytorch-lightning/pull/11594))

|
||

|
||

||
- `ModelCheckpoint(save_last=True, every_n_epochs=N)` now saves a "last" checkpoint every epoch (disregarding `every_n_epochs`) instead of only once at the end of training ([#12418](https://github.com/PyTorchLightning/pytorch-lightning/pull/12418))
|
||
- The strategies that support `sync_batchnorm` now only apply it when fitting ([#11919](https://github.com/PyTorchLightning/pytorch-lightning/pull/11919))
