How to use saved .pkl parameters file?

[Ruid6]

I have modified the smpl model and saved the pkl file，but i not load it in SMPL code.
`def ready_arguments(fname_or_dict):

if not isinstance(fname_or_dict, dict):
    #dd = pickle.load(open(fname_or_dict))
    dd = pickle.load(open(fname_or_dict,"rb"),encoding='iso-8859-1')
else:
    dd = fname_or_dict
    
backwards_compatibility_replacements(dd) `
