How to save mesh without background？

[hicookie77]

When I add the command（--empty_bg）, I get the following error： Traceback (most recent call last): File "/home/xu/anaconda3/envs/pymafx/lib/python3.8/runpy.py", line 194, in _run_module_as_main return _run_code(code, main_globals, None, File "/home/xu/anaconda3/envs/pymafx/lib/python3.8/runpy.py", line 87, in _run_code exec(code, run_globals) File "/home/xu/PyMAF/apps/demo_smplx.py", line 605, in run_demo(args) File "/home/xu/PyMAF/apps/demo_smplx.py", line 457, in run_demo img, empty_img = renderer( ValueError: too many values to unpack (expected 2)

In addition, when I add the incomplete original image of the human body, the following error occurs, how should I solve it.
