Hello author, thanks for your excellent work.

But I have a problem: I would like to know what the data in brjathu/PHALP mean.

[:, [0]] means global_orient [:, 1:24] means body_pose

What about the others?Please reply to me at your earliest convenience. Thanks a million.

>>> npz.files
['pose', 'shape', 'cam']

pose is global_orient and body_pose in 6D rotation representation. (1+23)*6, mean pose params then convert to 6D-> rotMat.

shape is the average body shape beta_0 that the HMR iterative regressor starts from. cam is the default camera p_0 that the iterative regressor starts from
