Worked on stabilizing the local server configuration for the UKGovernmentBEIS/inspect_ai repository, focusing on backend development and system configuration using Python. Addressed a critical bug by refining the handling of empty command-line arguments and improving the logic for CUDA device selection, specifically updating the CUDA_VISIBLE_DEVICES environment variable. Adapted the parallel size parameter to dynamically reflect available GPUs, which reduced deployment friction and improved reliability in local development and testing environments. These changes enhanced the developer experience by minimizing environment-related failures and streamlining onboarding for data science workflows, resulting in a more robust and flexible local server setup for the project.
