hello,
I really appreciate this work, thanks very much.

And I have a question here, some data provide by eft is come from posetrack, and there are two version of posetrack, that is posetrack2018(82G) and posetrack2017(34G). I want to know which version of posetrack is used here, it's a hard work to download all of the data.
