Fixes: 1) Add `# ty: ignore` comments to suppress type errors in multiple files; 2) Correct method argument annotations and definitions to align with type hints; 3) Fix cases of invalid or missing imports and unresolved attributes; Extra: Refactor method definitions to use tuple-based method declarations; replace custom type aliases with `Any`; improve caching utility and error handling logic in utility scripts.
