some problems occur running demo

[haolianyi]

Hi, thanks for open source.
When I use the command python demo.py --demo /cluster/home/it_stu14/3DHP/images/mpii_2.png [--gpus -1] [--load_model /cluster/home/it_stu14/3DHP/models/fusion_3d_var.pth]
I got the error :
demo.py: error: unrecognized arguments: [--gpus -1] [--load_model /cluster/home/it_stu14/3DHP/models/fusion_3d_var.pth]
I want to ask for some help, thanks!

I think the mean of "[ ]" is optional and you should delete it or it and the content inside it

hi:
Sorry for bother, in human pose estimation with MPI-INF-3DHP often use pck as the criterion with theshold of 150mm. In the criterion, the scale factor will multiply the distance between estimation and ground truth. So how to compute the scale factor . @funihang
