Question about well-trained checkpoint

[imabackstabber]

hi, I've been trying to use your checkpoint for my private project. I wonder whether I can train my own pct, so I train them on COCO solely. After that, I plug the obtained model into my project, but it seems that it yielded subpar results.
I want to know the publicly available checkpoint is trained on what datasets @Gengzigang
Looking forward to your reply.
