I am using Kaggle for training and for submissions, because they provide for free notebooks with 4 CPU cores and 30GB RAM. Their notebook scheduling capability is not usable for numerai submissions, so I have created workaround solution with (always ) free Oracle Cloud compute node, running Kaggle public API and
cron
trigerring my numerai notebooks at announced round openning times. Inside of my notebooks I wait for actual round openning.
To sum it up: I remain at big fat zero automation costs
