      # Arguments
  
          module: The module to fetch the classes from. If it's a string, it
              should be in the dotted format. `'keras.layers'` for example.
          exclude: The names which will be excluded from the returned list. For
              example, `get_classes('keras.layers', exclude=['Dense', 'Conv2D'])`.
          return_strings: If False, the actual classes will be returned. Note that
              if you use aliases when building your docs, you should use strings.
              This is because the computed signature uses
              `__name__` and `__module__` if you don't provide a string as input.
  
      # Returns
  
       A list of strings or a list of classes.
