Clarification on different Mean files

[kai-lan]

I found there are multiple mean files. One is Mean.npy and 'Std.npyfrom [HumanML3D](https://github.com/EricGuo5513/HumanML3D/tree/main/HumanML3D). The one you provided under./checkouts/t2m/release/metaseem to match the the one from Guo's evaluator/checkpoints/t2m/Comp_v6_KLD01/` from here. Can you confirm if they are actually the same? And which mean and std did you use for training?
