Please see [the training README](training/README.md) for more details about customizing the training run.

The `training/finetune_Pythia-Chat-Base-7B.sh` script is another example to fine-tune a 7B pythia (gpt-neox) model. The script launches 8 processes with a pipeline-parallel degree of 4 and a data-parallel degree of 2.
