This changes
defaults.py
to source defaults directly from theTrainerConfig
,OptimizerConfig
, andBaseCombinerConfig
marshmallow schemas.Going forward, we'll have a single source of defaults (the schemas). Merging with the full schema also enables Ludwig to print and save comprehensive configs, which contain an exhaustive list of parameters, for Trainer and Combiner, insulating older models from subsequent changes to module constructor values, like #2050, which we reverted in #2069.
