cannot import name 'Attention' from 'timm.models.layers'

This error message suggests that there is an attempt to import the class 'Attention' from the module 'timm.models.layers', but the import failed because the class is not defined in that module.

There could be several possible reasons for this error, such as:

1. The version of the 'timm' library being used is outdated, and the 'Attention' class has been removed or renamed in a newer version.

2. The 'Attention' class is defined in a different module or package within the 'timm' library, and the import statement needs to be modified accordingly.

3. There is a typo or syntax error in the import statement or in the definition of the 'Attention' class itself.

To resolve this error, you may need to check the documentation and examples of the 'timm' library to determine the correct way to import the 'Attention' class. You may also need to update your version of the library, or check your code for any mistakes or errors.
