[question] why doesn't TPOT store checkpoint?

I understand since TPOT would randomly select pipelines, you could use a pseudo-random generator and set a seed for that and export the information to some file.

I used `periodic_checkpoint` flag and `warm_start=True` but even then, TPOT doesn't resume from the generation it left off, rather it just starts from scratch.

any workaround to get this checkpoint?
