During August 2025, Zhangfei contributed to the pytorch/pytorch repository by enabling RISC-V cross-compilation support, expanding PyTorch’s compatibility with emerging hardware platforms. Zhangfei updated Docker build scripts and CI workflows, integrating toolchain configuration and dependency management for RISC-V builds using Python and Shell scripting. This work automated validation of cross-compilation paths within the CI/CD pipeline, reducing manual intervention and streamlining build processes for developers. By focusing on cross-compilation and DevOps practices, Zhangfei’s changes allowed for early testing and feedback from hardware partners, laying the groundwork for broader hardware support. The work demonstrated depth in build infrastructure and automation.
