Changelog
v0.2.0 (09/10/2020)
OneFlow 已经开源72天啦,现在也迎来了0.2.0版本,在这个版本中, OneFlow 进行了不少性能优化,在分布式性能最快的道路上继续狂飙。针对国内用户优化编译体验,从此下载编译 OneFlow 快到飞起。
除此之外,本次更新的亮点还有:
1. grpc 版本升级到最新版,消除老版本 grpc 带来的编译障碍;
2. Tensorflow XLA 升级到了最新版;
3. 我们做了大量工作来增强稳定性、图编译和运行速度,即将发布深度学习框架测试报告,可关注 Oneflow-Inc/ DLPerf 项目先睹为快;
4. 您可能已经关注到了我们正在快马加鞭地优化 OneFlow 的动态图机制, C++ 和 Python 交互方式正在从 SWIG 向 Pybind11 迁移,届时 OneFlow API 至少和 PyTorch 一样好用(如果不是更好用)。
5. API 文档进一步完善,更多示例更易懂。
