What's the use of "ignore_mask"

[tracer9]

Hi, TreB1eN:
Thanks for sharing this pytorch version of openpose. I really loves your comments. When I try to dive into the code, I found the dataloader generates "ignore_mask" from the folder(see link). However, accroding to your guide, I can't find this.

Could you help to explain the usage of "ignore_mask"?
