Bumps paddlepaddle from 1.8.5 to 2.5.0.

Release notes

Sourced from paddlepaddle's releases.

PaddlePaddle 2.5.0 Release Note

1. 重要更新

  • 动静统一新架构:实现基础算子组合的动转静加编译器执行新模式,在ResNet50&Bert模型上完成动转静、组合算子、神经网络编译器优化加速全流程。动转静完成整图fallback核心功能开发,支持动转静失败时回退到动态图训练执行;组合算子设计一套包含150多个基础算子的基础算子体系,实现python层前向算子拆分机制和支持动、静态图的反向算子拆分机制,实现70多个常用前、反向算子的拆分;CINN编译器修复正确性问题,开发关键Pass,添加手工Schedule规则,实现内核代码自动生成,ResNet50模型性能提升12%,Bert模型性能提升10%。
  • PHI算子库算子架构统一:将原算子体系下剩余的350+算子内核全部统一到PHI算子库中,以及原算子体系中的算子定义方式也都统一为PHI算子库的算子定义形式(基于YAML配置定义算子),提升了架构统一性,降低了框架开发的理解成本;将PHI算子库依赖的Fluid头文件全部解耦,并独立编译为动态链接库,为框架的二次开发提供更轻量的算子库复用方式;继续对飞桨框架中不规范的算子以及算子内核进行规范化调整,便于开发者理解,降低了硬件的接入成本。
  • 静态图新执行器全面上线:静态图新执行器实现多项功能和性能优化,完成对原有多套旧执行器的统一和替换,成为静态图单卡和分布式训练python端入口以及动转静、控制流、CINN等后端默认使用的执行引擎,大幅提升框架调度性能,功能架构更加清晰,二次开发能力显著增强。
  • Python API 支持0维tensor:为形状为[1,] 及形状为 [] 的张量定义了清晰的语义。
  • 新的环境适配:适配了CUDA 12,并支持使用gcc12进行编译。

2. 不兼容升级

  • 飞桨API支持0维tensor。飞桨之前用shape为[1]的1维tensor来替代0维tensor,这种替代方式和当前主流习惯有差异,增加模型的开发调试成本,有时还会导致非预期错误。本版本对需支持0维tensor的376个API进行了修正,和社区广泛使用的工具如EinOps等实现。例如,在之前的情况下,模型训练中输出的loss为1维tensor,如果要取出或打印loss,往往需要使用 loss.numpy()[0] 这样的代码。经过本次修改后,模型训练中输出的loss为0维tensor,使用 loss.numpy() 即可取出或打印loss,代码简短、易懂且符合业界使用习惯。
  • paddle.fluid API全面退场。按照上个版本已预告的计划,本次退场了1116个paddle.fluidAPI及相关内部接口,剩余少量相关内部接口会在下个版本全部清理完成。fluid API属于飞桨2.0本计划移除但考虑到兼容性等因素延缓清理的历史API,本次退场清理不会影响基于飞桨2.0开发的程序,飞桨API体系也会更加简洁易懂。
  • 旧版动态图Python端代码完成清理。至此,Python端仅使用新版动态图调用C++核心逻辑。
  • 为统一静态图模型数据并行的训练方式,废弃原有的单进程多卡训练方式,包括 paddle.static.ParallelExecutorpaddle.static.CompiledProgram().with_data_parallel() 两个接口,原因是这套接口只支持单机多卡,不支持多机多卡,且底层执行性能较差。推荐统一使用多进程多卡训练方式,即 paddle.distributed.launch 接口来进行数据并行的分布式训练。该升级只影响静态图,不影响动态图和动转静训练,如果使用了废弃接口,请参考 数据并行 的文档修改模型代码。#50351#50501#51240#51701#51616#51369#52671
  • 移除框架中原有的昇腾NPU和寒武纪MLU的适配代码,全部升级为CustomDevice插件式适配方式,并将昇腾NPU和寒武纪MLU的适配代码迁移至PaddleCustomDevice仓库。
