[igraph] Plotting --> AttributeError: 'bytes' object has no attribute 'encode'

[roberto franceschini]

Hello, in python I am doing

G = igraph.Graph.Full(10)

igraph.plot(G, bbox = (400,400), layout = G.layout('kk'))

and I get 

AttributeError                            Traceback (most recent call last)
/usr/local/lib/python3.6/site-packages/IPython/core/formatters.py in __call__(self, obj)
    309             method = get_real_method(obj, self.print_method)
    310             if method is not None:
--> 311                 return method()
    312             return None
    313         else:

/usr/local/lib/python3.6/site-packages/igraph/drawing/__init__.py in _repr_svg_(self)
    352         surface.finish()
    353         # Return the raw SVG representation
--> 354         return io.getvalue().encode("utf-8")
    355 
    356     @property

AttributeError: 'bytes' object has no attribute 'encode'

I cannot find a match for this in google or stackoverflow. Since I have never used plots of iGraph before in Python I thought was best to ask.

Thanks for helping,
