If your optimization problem is multi-objective, Optuna assumes that you will specify the optimization direction for each objective. Specifically, in this example, we want to minimize the FLOPS (we want a faster model) and maximize the accuracy. So we set directions to ["minimize", "maximize"]. study = optuna ... check if bolt action firearm is unloaded
