NameError: name 'all_model_paths' is not defined

Hi, the notebook for subtask B and C are not runnable at all.
When running chosen_models = [all_model_paths[i] for i in final_optimal_models] in both notebook B and C, they both return this error:

---

Seems you don't have this variable in the notebook. To reproduce, just run the notebook you put in github.

Also, the subtask A notebook is also not runnable. We also have the "unhashable type: 'dict' while using batch_generator" error which is already mentioned in another Issue. Hope you can do a most basic check before uploading the notebooks. Thank you.
