there are some dependencies that I think shouldn't be here:

  1. model-tools (this repo) should not depend on candidate_models. Instead, models should be passed externally in the init function (check e.g. here for an example of what I mean)
  2. some pieces of the code seem to be specific to the data that is used in the specific benchmark. Ideally this code would be independent of the specific data so that it can be applied to other data too, but I understand if that's too much work

It would also be great if there was a unit-test to demonstrate and test the functionality added here

The only thing missing here is to use the assigned V2 layer (found here

def commit_region(self, region):
layer_selection = LayerSelection(model_identifier=self.layer_model.identifier,
activations_model=self.layer_model.activations_model, layers=self.layers)
benchmark = self.region_benchmarks[region]
best_layer = layer_selection(selection_identifier=region, benchmark=benchmark)
self.layer_model.commit(region, best_layer)
) for the search image features, right?

should these not be the same? Sorry I'm getting confused with these parameters hidden in dictionaries

No these will not be the same. As I previously mentioned that the input image size will be different for the target_image and stimuli_image. You will need two different ML models for both.

def start_task(self, task: BrainModel.Task, **kwargs):
self.fix = kwargs['fix'] # fixation map
self.max_fix = kwargs['max_fix'] # maximum allowed fixation excluding the very first fixation
self.data_len = kwargs['data_len'] # Number of stimuli

shouldn't this just be the length of the stimulus_set, why do we need to pass this?

Yes, this will be the same. I will change this. Thanks for pointing out.
