Generators used for pre-training

The paper mentions the use of a SQL-to-Text and Table-to-Text model to generate synthetic samples for pre-training. I would like to use these models to try generate synthetic training examples for my own custom datasets. It doesn’t seem like the weights for these models were made public, is there any way I can train these models myself? I saw some code under `relogic` and `pretrainkit` which seems relevant for this but couldn’t figure out what data it uses and how to run it. Thanks!
