[PBT] Retrieve the best hyperparameter config from PBT training

[Kai_Yun]

After 147 checkpoints and 106 perturbations, my Population-based training is done.

The problem is that I did not ask for the best_config at the end of training, and thus am not able to retrieve the best configuration. Does anyone know how to find the best hyperparameter configuration from training? It’ll be such a waste if I can’t find it after 20 hours of training…

Thanks in advance!

PBT hyperparameter configs are constantly changing; you’ll need to look at the checkpoints generated. the Tune Analysis object would help you do the postprocessing to identify the best checkpoint here.
