Description

Related to #79289 and #79290.

This PR cleans Python 3.10 type-hint modernization diagnostics and enables Ruff's Python 3.10 target:

merge latest develop after [Typing] Upgrade mypy to 2.1.0 and target Python 3.10 #79289/[CodeStyle] Clean up Python 3.9 compatibility code #79290 and resolve the resulting conflict without force-push
set Ruff target-version = "py310"
clean py310 UP035 / UP007 / UP045 diagnostics by modernizing type-hint syntax and removing now-obsolete typing imports
keep runtime-sensitive forward references semantically equivalent where direct evaluation would be unsafe
keep test/compat/test_torch_proxy.py coverage for evaluated torch.device | None behavior
remove stale docstring-example # type: ignore suppressions that became unused after the type-hint cleanup

Validation:

ruff check . --fix ✅
ruff check . ✅
git diff --check upstream/develop...HEAD ✅
python3.10 py_compile for 132 modified Python files ✅
pre-commit run --files $(git diff --name-only --diff-filter=ACMRT upstream/develop...HEAD) ✅

是否引起精度变化

否

另外我觉得 UP035、UP007 也可以在这个 PR 里一起做了呀，都是类型提示相关的改动

SigureWang · 2026-06-09T16:41:38Z

整体看这组改动只是把 Optional[T] 清理为 PEP 604 的 T | None，并同步移除无用 import，语义上没有看到明显行为变化。

需要注意的兼容性前提是：这些文件现在会直接使用 | 类型联合语法，因此运行环境必须已经是 Python 3.10+。如果当前分支仍需要兼容 Python 3.9 或更低版本，这会变成语法级不兼容；仅从本次 diff 无法确认项目的最低 Python 版本是否已经提升。

测试风险方面，test/compat/test_torch_proxy.py 中断言从 Optional[torch.device] 改为 torch.device | None 是合理的，但它依赖 torch.device 对 | 联合类型的行为正常。如果这是为 Ruff/pyupgrade 规则清理，建议至少确保相关 compat 测试在 Python 3.10+ 环境覆盖到，避免 torch.device 这类代理类型在类型联合构造时出现兼容问题。

ShigureNyako · 2026-06-09T16:47:49Z

已按建议补充到同一个 PR，见 ef578ce。

这次一起清理了全仓 py310 target 下的 UP035 / UP007，并更新了 PR 标题和 description。验证结果：

ruff check . --target-version=py310 --select UP035,UP007 通过
ruff check . --target-version=py310 --select UP035,UP007,UP045,UP036 仅剩 [CodeStyle] Clean up Python 3.9 compatibility code #79290 已覆盖文件里的 7 个 UP036
pre-commit run --files $(git diff --name-only upstream/develop) 通过
python3.10 -B -m py_compile $(git diff --name-only upstream/develop -- '*.py') 通过

这个 PR 先别 rerun 了，相关问题等 #79289 解决了再说吧

SigureMo · 2026-06-10T08:33:22Z

@ShigureNyako #79289 和 #79290 合入了，merge 下最新代码，并解决下冲突，另外 ruff 的 target-version 可以改成 3.10 了，ruff 全量扫一下，修一下吧

SigureMo · 2026-06-10T08:39:39Z

对了，不许 force-push！

ShigureNyako · 2026-06-10T09:02:05Z

已按要求处理，且没有 force-push：

normal push 追加了 merge commit，把最新 develop（含 [Typing] Upgrade mypy to 2.1.0 and target Python 3.10 #79289 / [CodeStyle] Clean up Python 3.9 compatibility code #79290）合入本 PR，并解决了 python/paddle/vision/transforms/transforms.py 的冲突；
保留了 [CodeStyle] Clean up Python 3.9 compatibility code #79290 对 python/paddle/_typing/backport.py 的删除，没有重新引入；
将 Ruff target-version 改为 py310；
全量执行并修复/确认 Ruff。

本地验证通过：

ruff check . --fix
ruff check .
git diff --check upstream/develop...HEAD
python3.10 py_compile 132 个改动 Python 文件
pre-commit run --files $(git diff --name-only --diff-filter=ACMRT upstream/develop...HEAD)

后续仍不会 force-push。

Remove obsolete RUF100 suppressions and the inactive FA100 token from the evaluated Optional torch.device coverage, keeping the active UP045 suppressions. Co-authored-by: Codex <noreply@openai.com>

不过喵的 static-check 里怎么有个下载的日志，导致完全看不到报错了，关键信息我提取了下：

已跟进 static-check，normal push 追加了修复提交 a93496b3bcc（未 force-push）。

处理内容：

修复 sample code type checking 报出的 16 个 API 示例问题：img.shape 前补充 paddle.Tensor 类型收窄，dtype 示例改用 paddle.float32 / paddle.bfloat16，Uniform 嵌套 list 示例改为 paddle.to_tensor，并清理/修正过期的 inline type: ignore。
保持示例运行输出不变，只补充类型检查所需的无输出断言或类型更明确的写法。

本地已过：

python3.10 -m py_compile（本次修改文件）
ruff check（本次修改文件）
git diff --check
pre-commit run --files ...

本地 tools/type_checking.py ... 因当前机器未安装可导入的 paddle wheel，无法完整复现；这次按 CI 提取出的 mypy 报错逐项修复。

别改人家代码语义

如果是我们类型上哪里有问题，就补全
如果实在不行，就 ignore

感觉就 datasets 下的文件改的合理，其他的都重新 review 下吧

ShigureNyako · 2026-06-10T11:38:42Z

已按 review 调整，normal push 追加了 f201f26b640（未 force-push）。

处理内容：

datasets 下已确认可接受的 paddle.Tensor 类型收窄保留。
其他 sample code 恢复原运行时语义：
- new_zeros(3, 3) 恢复，只改为正确的 type: ignore[arg-type]；
- Uniform 恢复嵌套 Python list，只加 type: ignore[list-item]；
- 字符串 dtype 示例恢复，通过 Literal 补全类型；
- distributed 示例恢复 dtype='int64'，只把 ignore 改成实际的 call-overload。

本地验证通过：

python3.10 -m py_compile（本次 6 个修改文件）
ruff check（本次 6 个修改文件）
git diff --check
pre-commit run --files ...

ShigureNyako · 2026-06-10T11:48:30Z

已继续按 review 调整，normal push 追加 f2f55f478aa（未 force-push）：

check_layer_numerics / incubate.inference 的 dtype 示例不再用 Literal，恢复用户更友好的原写法；
仅在触发 sample-code mypy call-overload 的 paddle.rand(...) 行加 inline ignore。

本地验证通过：

python3.10 -m py_compile（本次 2 个修改文件）
ruff check（本次 2 个修改文件）
git diff --check
pre-commit run --files ...

SigureMo · 2026-06-10T13:38:46Z

@ShigureNyako static-check 又挂了，自己想办法拉日志修复吧

ShigureNyako · 2026-06-10T14:16:21Z

已跟进最新 Static-Check / Test，normal push 追加 18a4235b2ae（未 force-push）。

本次 fresh log 里剩余 3 个 sample-code type checking 问题，都是 inline type: ignore code 不匹配：

new_zeros(3, 3) 实际报 misc，已改为 # type: ignore[misc]；
class_center_sample / margin_cross_entropy 的 paddle.randint(... dtype='int64') 还会在 int(num_classes.item()) 上报 arg-type，已改为 # type: ignore[call-overload,arg-type]。

只调整 ignore code，不改变示例运行语义。

本地验证通过：

python3.10 -m py_compile（本次 3 个修改文件）
ruff check（本次 3 个修改文件）
git diff --check
pre-commit run --files ...

ShigureNyako · 2026-06-10T14:28:34Z

已继续跟进最新 Static-Check / Test 日志，normal push 追加 e5fda85ed68（未 force-push）。

原因是 new_zeros(3, 3) 这行在 mypy 下同时可能触发 misc 和 arg-type，上一次只覆盖 misc 仍不够稳妥；现在改为：

# type: ignore[misc,arg-type]

只调整 inline ignore code，不改变示例运行语义。

本地验证通过：

python3.10 -m py_compile python/paddle/base/dygraph/math_op_patch.py
ruff check python/paddle/base/dygraph/math_op_patch.py
git diff --check
pre-commit run --files python/paddle/base/dygraph/math_op_patch.py
