WebFirst, you define the hyperparameters you want to tune in a search space and pass them into a trainable that specifies the objective you want to tune. Then you select a search algorithm to effectively optimize your parameters and optionally use a scheduler to stop searches early and speed up your experiments. WebNow let’s convert this to a distributed multi-worker training function! All you have to do is use the ray.train.torch.prepare_model and ray.train.torch.prepare_data_loader utility functions to easily setup your model & data for distributed training. This will automatically wrap your model with DistributedDataParallel and place it on the right device, and add …
