WebRun multi-objective optimization. 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 ... WebNote: The following two chapters discuss the advanced usage of Opacus and its implementation details.We strongly recommend to read the tutorial on Advanced Features of Opacus before proceeding.. Now let's look inside make_private method and see what it does to enable DDP processing. And we'll start with the modifications made to the DataLoader.. …
