AttributeError: 'Model' object has no attribute 'fusion_layers' - YOLOv5 Error Resolution

The error message 'AttributeError: 'Model' object has no attribute 'fusion_layers'' indicates that the 'Model' object you are using does not have an attribute named 'fusion_layers'.

This error typically occurs when you are trying to access an attribute or method that does not exist in the object you are working with.

To resolve this issue, you can check the documentation or source code of the 'Model' class to see if there is a different attribute or method that you can use instead of 'fusion_layers'. Alternatively, you can make sure that the object you are working with is an instance of the correct class that does have the 'fusion_layers' attribute.
