Asking about the 'efficientnet_key'

[dazaier]

Hi! Thank you for your amazing work! I have some questions about the parameter "efficientnet_key"， what is the purpose of this parameter? Is it to improve the model's inference time and reduce GPU memory usage? In your code, you have implemented two options, 'b5' and 'b4'. What do they represent respectively? Does using this parameter lead to a decrease in the accuracy of model inference?
