Hello CostlyOstrich36 , thanks for your question. At the moment I am training a MLP for a regression problem and in one case I want to store the number of neurons per layer. Note that in my case it is not a hyperparameter because I calculate the number of neurons based on the number of layers and the number of model parameters. Another case is that I want to store some local paths where the models are stored, since I currently don't have any remote storage set up for my models.
