##import pickle as cPickle
import pickle

and

        ##dd = pickle.load(open(fname_or_dict, 'r'), encoding='latin-1')
        with open(fname_or_dict, 'rb') as f:
            u = pickle._Unpickler(f)
            u.encoding = 'latin1'
            dd = u.load()

I have come to the realization that requiring the smpl_webuser package is a bit cumbersome. It's written to target python2 which causes the cPickle & this unpickling error. I will work to remove this dependency.

[benjiebob]

I have now removed the dependency. I've handwritten the code to set v_template for different quadruped classes rather than running it through the SMPL code. I'd be super grateful if you wouldn't mind testing the new code. 👍
