🌟 Summary

Minor refactors to improve code quality, readability, and linter compliance without changing functionality. ✅

📊 Key Changes

• Tests: Renamed unused params to _params in tests/test_conv2d.py to silence linter warnings.
• Exports: Reordered __all__ in thop/__init__.py (no change to what’s exported).
• Conv2d profiling: Prefixed unused arguments with underscores in thop/fx_profile.py and b_shape -> _b_shape to indicate intentional non-use.
• Logging: Slight f-string improvement in thop/profile.py ({m!s} instead of {str(m)}) for clarity.

🎯 Purpose & Impact

• Cleaner code and fewer linter warnings (helps maintainability and CI stability) 🧹
• No behavior changes or API breaks—safe for all users 🔒
• Slightly clearer logging messages for developers inspecting hooks 🪵
