Description

Hi, I'm using the scheuler population based trining (PBT). Currently, for each agent, the hyperparameters can be modified through exploit/explore process. While they are kept unchanged within in the Trainable class (i.e., learning rate remains the same during training iterations while might be changed only after exploit/explore). How we can optimize the hyperparameters (i.e., in bi-level optimization case) within the Trainable class and update the self.config accordingly? So that the optimized hyperprameter values appear when we recall Trainable class. Currently I update the self.config but it seems not work......

Hey @Jiamian-Wang! Do you mind giving an example of what you are trying to do? Do you want to be able to change the hyperparameters for PBT from within the Trainable?
