[FIXED] How can I choose the right number of epochs per trial in Optuna?

Issue

Is there a rule of thumb for how to choose the number of epochs per trial in Optuna?

Solution

I would imagine epochs are directly correlated with your computational costs, but perhaps that's a parameter worth optimizing. If you aren't sure, start with your best guess and run a few optimization studies with different epoch values. Once you confirm the importance of your epochs, you can conduct separate studies on just the epoch value.
