error when running ManoHand_xml2mesh.py on the given samples

[tumble3eed]

Thanks for your wonderful work!
However, I encoutered the following problem when trying the demo in ./samples:

$  python ./ManoHand_xml2mesh.py --xml_path ./samples/data.xml --mesh_path ./outputs/mesh.obj --part_path ./outputs/

    self.lb_eigen[off] = -np.finfo(np.float64).max
IndexError: index 2 is out of bounds for axis 0 with size 2

It seems that root.iter('EG') has a length > 2, against to the assert "off == 2"
my environment settings are as follows:

MANO                      0.1
trimesh                   3.12.7
torch                     1.11.0+cu113
defusedxml                0.7.1
lxml                      5.3.0

By the way, I wonder what "mm" means and what is the difference between hand_mesh and hand_mesh_mm?
