For crunch 3, can my infer just be reading a saved data frame of ranked genes ?
As long as you still include your train function which we can (re)run on unseen data and it does not crash.
I guess you were inspired by what Tarandros did in the quickstarter notebook?
The Crunch 3 logFC Quickstarter notebook says:
During the CrunchDAO submission, there is no need to run the
trainfunction. Simply, use theinferfunction loading the locally savedgene_ranking.csvfile.
That does not invalidate the fact that the training code is still necessary.
The infer function can indeed just read what the train outputted.
