Hi Krishnan

I have reported your comment as a bug. I think that this is pretty minor. As far as I can tell, the model still works perfectly. I have also seen this issue before; I think it arises from me having two different bits of code where 'matplotlib.use()' is called; I don't think it's a big concern.
