Why is 3D Hand MPJPE different from the original InterHand2.6M paper ?

[suepiiin]

Hi,

I noticed that mmpose has a much better MPJPE than the InterHAnd 2.6M paper. For example, the single hand MPJPE for mmpose is 9.47, but in the paper it is 12.16. This is a good result, but I do not know why. What is the reason?
