During March 2026, Zhouyu worked on the alibaba/ROLL repository, focusing on stabilizing the on-policy distillation workflow. By identifying and correcting a configuration name typo in the run_onpolicy_distill_pipeline.sh script, Zhouyu restored proper execution of the pipeline, directly reducing failures and improving experiment reliability. This scripting work, leveraging Shell and devops skills, ensured that distillation experiments could run reproducibly and aligned with production service level agreements. Although the contribution was limited to a single bug fix over one month, the targeted change addressed a critical bottleneck, enabling faster iteration cycles and supporting developer productivity within the broader machine learning infrastructure.
