Extract_cluster from DeepCluster_V2 pretrained model and visualisation (#364) #417

Closed DC95 closed 3 years ago

DC95 commented 3 years ago

Summary:

For DC_V2 Cluster_assignment_extraction + visualisation_yaml_config

This PR introduces:

  1. Changes in the trainer_main.py and base_ssl_model.py to adjust the head configuration of DC_V2
  2. Yaml file config to extract clusters from the DC_V2 train checkpoint.

My own doubts -

Forgive me for my mistakes; I don't feel confident whether changing -

  1. prototype_index[idx].item() to prototype_index.item() is doing the correct job in base_sslmodel.py. I changed it because it was otherwise showing the error - 'IndexError: invalid index of a 0-dim tensor. Use tensor.item() to convert a 0-dim tensor to a Python number'_
  2. I also understand that in DC_V2, we use multi clustering, and for that we there are multi heads (i.e., len(self.heads) >1).

This is as far as my understanding goes. Kindly improve it as I am in urgent need of the visualization of the DCV2 Cluster assignments.

Regards, DC

Kind note - Rest we can proceed with cluster_assignments_to_dataset.py as given in the link

Is this PR still needed? @DC95 I know we resolved the issue of saving the deepcluster clusters.
