transfer_model issue : AttributeError: 'Struct' object has no attribute 'hands_componentsl'

[HwangGB]

Hi,

I'm encountering the error message in the title when following this guide for model parameter transfer:
SMPL-X Model Transfer Guide.

I want to transfer SMPL-X male model data to SMPL data, so I modified the write_obj.py code from line 18 to 30 like this:

def main(
    model_folder,
    motion_file,
    output_folder,
    model_type="smplx",
    ext="npz",
    gender="male",
    plot_joints=False,
    num_betas=10,
    sample_expression=True,
    num_expression_coeffs=10,
    use_face_contour=False,
):

I used this command line to break the motion into a set of pose .obj files:

python write_obj.py --model-folder ../models/ --motion-file ../transfer_data/our_data/smplx_test.npz --model-type "smplx" --output-folder ../transfer_data/meshes/test/

However, I encountered this error message:

python write_obj.py --model-folder ../models/ --motion-file ../transfer_data/our_data/smplx_test.npz --model-type "smplx" --output-folder ../transfer_data/meshes/test/
arr_0 ()
male
10

                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'Struct' object has no attribute 'hands_componentsl'

How can I solve this problem?

Thanks in advance.
