| ### 实习项目 | ||
|
|
||
| Paddle API兼容性增强 | ||
|
|
||
|
|
||
|
|
||
| ### 本双周工作 | ||
|
|
||
| 1. **torch.std对齐** | ||
|
|
||
| - https://github.com/PaddlePaddle/Paddle/pull/77006 | ||
| - https://github.com/PaddlePaddle/PaConvert/pull/804 | ||
| - https://github.com/PaddlePaddle/PaConvert/pull/813 | ||
| - https://github.com/PaddlePaddle/docs/pull/7680 | ||
| - 状态：CI通过，等待合入 | ||
| - 所属：API兼容性增强任务 | ||
| - 描述： | ||
| - 在PaConvert增强对应的测试用例，补充中文文档修改 | ||
| - 内容详情详见上次双周周报 | ||
|
|
||
| 2. **abs_下沉** | ||
|
|
||
| - https://github.com/PaddlePaddle/Paddle/pull/77294 | ||
| - https://github.com/PaddlePaddle/PaConvert/pull/811 | ||
| - https://github.com/PaddlePaddle/docs/pull/7697 | ||
| - 状态：全部已合入 | ||
| - 所属：API兼容性增强任务、inplace API下沉系列任务 | ||
| - 描述： | ||
| - 在PaConvert增强对应的测试用例，补充中文文档修改 | ||
| - 内容详情详见上次双周周报 | ||
|
|
||
| 3. **`paddle.utils.data.*`对齐** | ||
|
|
||
| - https://github.com/PaddlePaddle/Paddle/pull/77391 | ||
| - https://github.com/PaddlePaddle/Paddle/pull/77446 | ||
| - https://github.com/PaddlePaddle/Paddle/pull/77451 | ||
| - https://github.com/PaddlePaddle/Paddle/pull/77591 | ||
| - https://github.com/PaddlePaddle/PaConvert/pull/817 | ||
| - 状态：CI通过，等待合入 | ||
| - 所属：API兼容性增强任务 | ||
| - 描述： | ||
| - 实现了上个双周的方案，通过`paddle.utils`的按需导入，延后了对应类和方法的导入时机，不会触发循环依赖，同时补充了对应的单测 | ||
| - PaConvert测试过程中发现存在`torch.utils.data.dataloader.default_collate`这个用法，在torch文档里没有写，paddle的API差异文档也没写，但PaConvert做了测试，所以后来加了一下别名 | ||
| - 目前处理了"仅API调用方式不一致"的所有API（10个API） | ||
|
|
||
| 4. **装饰器优化** | ||
|
|
||
| - https://github.com/PaddlePaddle/Paddle/pull/77497 | ||
| - https://github.com/PaddlePaddle/Paddle/pull/77561 | ||
| - 状态：全部已合入，系列任务进行中 | ||
| - 所属：API兼容性增强任务、衍生的杂项任务 | ||
| - 描述： | ||
| - 有些API为了实现兼容性，使用了自己定义的装饰器，后来定义了通用的别名装饰器，自定义装饰器性能会比通用装饰器差一点，所以尽量替换为通用装饰器 | ||
| - 通用装饰器`ParamAliasDecorator`可以处理任意别名情况，但性能较差，将单参数别名和双参数别名的替换为`param_one_alias` 和`param_two_alias`提高性能 | ||
|
|
||
|
|
||
|
|
||
| ### 下双周工作 | ||
|
|
||
| 1. **`paddle.utils.data.*`对齐**的中文文档修改 | ||
| 2. **装饰器优化**进行下一子任务：自定义装饰器代码可读性差，通过overload维护方法签名增强可读性 | ||
| 3. **inplace API下沉系列任务**进行下一子任务：inplace API的`python_api_info.yaml`解析处理（原先逻辑似乎是直接用非inplace版本的配置，不够灵活） | ||
| 4. 继续认领完成其它任务 | ||
|
|
||
|
|
||
|
|
||
| ### 导师点评 | ||
|
|
||
| 杨锃砚同学半个月来积极开展工作，顺利完成了多个API的兼容性增强，同时完成3个API机制优化的工作： | ||
|
|
||
| 1. inplace下沉机制优化 | ||
| 2. `torch.utils.data.*`批量对齐与导入路径设计 | ||
| 3. 装饰器性能与可读性优化 | ||
|
|
||
| API机制优化的工作，相比单个API更有难度，体现出对Paddle代码有了较好理解。后续将上述工作继续收尾，由于机制优化工作更为重要，在日常工作中需优先开展，然后再开展剩余API的对齐。 | ||
