Eduardo Sanchez updated the end-to-end fine-tuning documentation for the facebookresearch/fairseq2 repository, focusing on improving guidance for distributed training setups. He clarified the use of the --gpus-per-node flag within the srun command, helping users configure multi-GPU environments more effectively. Working primarily with reStructuredText (RST), Eduardo enhanced the documentation to align with best practices for distributed training and reduce potential misconfigurations. His work addressed onboarding challenges by making command-line arguments more transparent for developers. The update demonstrated a strong attention to detail in technical writing and contributed to a smoother setup process for users working with multi-GPU training workflows.
