Recovered Mesh from Rotation in processed_motion

[yw0208]

Hi, I tried to visualize human mesh according to rotation in npy file of processed_motions.
This is what I got:

    motions = np.load("InterHuman/motions_processed/person1/1.npy")
    motions = torch.from_numpy(motions)
    motions=motions[:,62*3: 62*3+21*6].reshape(-1, 21, 6)
    motions=rotation_6d_to_matrix(motions)
    motions=matrix_to_axis_angle(motions)
    zero=torch.zeros(motions.shape[0], 1, 3)
    motions=torch.cat([zero, motions, zero, zero], dim=1)
    motions=np.array(motions)[0].reshape(-1)
    joblib.dump(motions, 'scratch/temp/intergen_obj/pro_test.pt')

I get rotation like this, and input the 72-dim vector as pose to the SMPL model.
Do you have any advice to fix it?
