unbound variable for `glmnetPlot`

when running the notebook example in https://github.com/bbalasub1/glmnet_python/blob/master/test/glmnet_examples.ipynb,

under multinomial logistic regression, the line glmnetPlot(fit, xvar = 'lambda', label = True, ptype = '2norm'); will crash.

UnboundLocalError: local variable 'ncl' referenced before assignment

checking the source code, seems that ncl is undefined in this conditional branch. Looks that it's not some life-or-death error. Still, it's troublesome.

I installed from source, from commit 18e6d6c
