Where to find PCB dataset for autorouting?

Hi, I'm completely new to PCB autorouting and just started exploring it. I've figured out that AI is now a big thing for predicting routes, but it seems that many researchers are facing issues with datasets. I found some of their GitHub links, but the datasets are either missing or the code to generate them is broken. Is there any way to get PCB datasets specifically for autorouting? I've seen many datasets for PCB defects, but not for this purpose.
