[Lint]Style: Convert `vllm-ascend/compilation` to ruff format (#5912) ### What this PR does / why we need it? Convert `vllm-ascend/compilation` to ruff format. ### Does this PR introduce _any_ user-facing change? During this migration, we encountered some **errors** in our CI and testing environments, such as: ``` vllm_ascend/utils.py:653: in <module> def register_ascend_customop(vllm_config: VllmConfig | None = None): ^^^^^^^^^^^^^^^^^ E TypeError: unsupported operand type(s) for |: 'NoneType' and 'NoneType' ``` **1. Root Cause Analysis:** The project uses a common pattern to break circular dependencies: ```python if TYPE_CHECKING: from vllm.config import VllmConfig else: VllmConfig = None # Placeholder assigned at runtime ``` When Python parses the function definition `def register_ascend_customop(vllm_config: VllmConfig | None)`, it attempts to evaluate the expression `VllmConfig | None`. Since `VllmConfig` is assigned `None` at runtime, the expression effectively becomes `None | None`. In Python, `None` is an instance of `NoneType`. While the `|` operator is implemented for Type objects (classes), it is not supported for `NoneType` instances, leading to the `TypeError` shown above. **2. Solution:** To maintain the modern `|` syntax required by our new linting standards while preserving our dependency management strategy, I have introduced: ```python from __future__ import annotations ``` at the top of the affected files. This enables **Postponed Evaluation of Annotations (PEP 563)**. **3. Impact and Benefits:** - By enabling `annotations`, Python no longer executes the `VllmConfig | None` operation during module load. Instead, it stores the annotation as a string literal, completely avoiding the `None | None` calculation. - We can keep the `VllmConfig = None` placeholders. This ensures that other modules can still import these symbols without triggering an `ImportError`, maintaining a stable dependency graph. - IDEs and static type checkers (MyPy/Pyright) continue to resolve the types correctly. This allows us to use modern syntax without sacrificing type safety or runtime stability. - The only side effect is that `__annotations__` will now return strings instead of type objects. Since this module does not use runtime type enforcement or reflection, this change has zero negative impact on existing functionality. ### How was this patch tested? - vLLM version: v0.13.0 - vLLM main: https://github.com/vllm-project/vllm/commit/11b6af5280d6d6dfb8953af16e67b25f819b3be9 --------- Signed-off-by: MrZ20 <2609716663@qq.com>
