Resuming from a checkpoint

Resuming from a checkpoint#

The following extra CLI options can be passed to the ae, epd, and train-eval subcommands (or added to configuration files):

Resume from a saved checkpoint. The default is to perform a full-state resume, which restores model + optimizer/scheduler/trainer loop state.
```
--resume-from path/to/encoder_processor_decoder.ckpt
```

To additionally reset the timer budget:

--resume-from path/to/encoder_processor_decoder.ckpt ++trainer.max_time="00:04:00:00" ++train_eval.reset_resume_time_budget=true

To restore only the model weights and generate a fresh optimizer/trainer state:
```
--resume-from path/to/encoder_processor_decoder.ckpt ++trainer.max_time="00:04:00:00" ++train_eval.resume_weights_only=true
```
In conjunction with trainer.max_time, this allows you to continue training with a fresh timer budget. Note that if resume_weights_only=true is set without a checkpoint, AutoCast raises an error.
