How can I modify the code to fit my own dataset?

i want train in my own dataset with 1920×1080 resolution, and the num_joints change to 19. But i meet some problem:
ValueError: Caught ValueErro in DataLoader worker process 0.
ValueError: operands could not be broadcast together with shapes(1080,1920) (1080,1920,1) (1080,1920).

Also, I used COCO Annotator to annotate the data, and the exported format seems to be slightly different from the annotation format of this project, does it have any effect? How do I need to convert it?
