As model size grows, it takes more time to save a model to the disk. The problem is significant during grid search, where thousands of large models could be saved during the process, leading to spending more time (& money, if applicable) on grid search.
For example, let's say it takes 20 seconds to save a mode. When training a model with 50 epochs and 80 trials (a trial means a whole training process), it will take 22 (20 / 60 / 60 50 80) hours for saving models on a single GPU, which is a waste of time (& money, if applicable).
This PR reduces the model size to 1/3 by removing optimizer states during grid search.
