🌟 Summary

Improved clarity in neural network layer initialization.

📊 Key Changes

• Clarified the act parameter passing when initializing Conv layers in Focus and GhostConv modules.

🎯 Purpose & Impact

• The purpose is to make the code more readable and to ensure the act argument is explicitly named during the construction of Conv layers.
• This ensures any future changes to the default values or behavior of act in the Conv class constructor will not impact these modules inadvertently, enhancing code maintainability.
• Users should not experience any functional changes, but developers can appreciate clearer code and more predictable behavior when adjusting or extending these classes. 🛠💡
