0.38.1

:bookmark: Release v0.38.1

0.38.0

Main changes

• Resuming from checkpoint moved to the TrainerConfig (setting resume_from_checkpoint in Trainer.train() is now deprecated and raises error)
• Resuming from checkpoints now supports inner-loop steps instead of only epochs
• Add data sampler for slicing data loaders (mainly used for training resumption)
• Re-order objects initialization in the Trainer's init function
• Add support for optimizer checkpointing in Trainer
• Add option to disable preprocess and post processing in Model.predict()
• Seperate generation config in Whisper's model config with a separate data class
• Drop support for Python 3.9

0.36.0

v0.36.0

1. Add gradient accumulation support to the Trainer

Now, you can set gradient_accumulation_steps (defaults to 1 which is the same as regular training) in the TrainerConfig to enable this feature. This technique can mimic having larger batch sizes without changing the actual batch size! For example, having batch size of 16 and gradient accumulation steps of 4 equals to having batch size of 64! This can lead to faster convergance.

2. Implement tools for training speech recognition models

In this release we added SpeechRecognitionDataset, SpeechRecognitionDataCollator and SpeechRecognitionMetricsHandler so that you can easily train or finetune a Whisper model. Take a look at this example.

3. Split and refactor in Trainer for better subclassing

We split the training_step function of the Trainer in a way that now it only takes care of forward/backward pass and the optimization step is now moved to its own method called optimization_step. Also added lr_scheduler_step for customizing LR scheduling step.

4. Add support for more LR schedulers
