Previous attempt at removing this hack broke generation, evals, and resuming training from checkpoint (namespaces were slipping through, despite conversion to omegaconf - need to track down where that happens).
This seems unrelated to this task - please open a separate issue tracking. For reference, we are using version 2.1.1 for omegaconf (should pin this version here too).
