This is actually how it's spelled in the original COCO dataset (https://arxiv.org/pdf/1405.0312, page 14). I don't really want to diverge from that, so I think we should keep the original spelling. Perhaps a note that this is the original spelling is warranted?

just some advice for the future, if you leave this blank github will make checkboxes. alternately, you can fill them by doing - [x] like so

Oops, sorry.
Weird that it's spelled that way, but I guess as long as it works it's fine.

I changed it back to how it was previously and added a comment as @Gold856 suggested.
