the past hidden states for their predictions. If this argument is set to a positive int, the `Trainer` will
use the corresponding output (usually index 2) as the past state and feed it to the model at the next
training step under the keyword argument `mems`.

`output_dir` will begin a git directory synced with the repo (determined by `hub_model_id`) and the content
will be pushed each time a save is triggered (depending on your `save_strategy`). Calling

If `output_dir` exists, it needs to be a local clone of the repository to which the [`Trainer`] will be
pushed.
resume_from_checkpoint (`str`, *optional*):

- `"every_save"`: push the model, its configuration, the tokenizer (if passed along to the [`Trainer`]) and
a draft of a model card each time there is a model save. The pushes are asynchronous to not block
training, and in case the save are very frequent, a new push is only attempted if the previous one is
finished. A last push is made with the final model at the end of training.
- `"checkpoint"`: like `"every_save"` but the latest checkpoint is also pushed in a subfolder named
last-checkpoint, allowing you to resume training easily with
`trainer.train(resume_from_checkpoint="last-checkpoint")`.
- `"all_checkpoints"`: like `"checkpoint"` but all checkpoints are pushed like they appear in the output
folder (so you will get one checkpoint folder per folder in your final repository)

API](https://pytorch.org/docs/stable/generated/torch.compile.html?highlight=torch+compile#torch.compile).
You can customize the defaults with the argument `torch_compile_backend` and `torch_compile_mode` but we
don't guarantee any of them will work as the support is progressively rolled in in PyTorch.
This flag and the whole compile API is experimental and subject to change in future releases.
torch_compile_backend (`str`, *optional*):
The backend to use in `torch.compile`. If set to any value, `torch_compile` will be set to `True`.
