PandasError: DataFrame constructor not properly called!

[Werner0]

I had to downgrade to Pandas 0.19.1 due to another error. Now I get the following error. Please provide the package versions you used:

import networkx as nx
from NetworkxD3.NetworkxD3 import simpleNetworkx
from IPython.display import IFrame 

G = nx.Graph()
H = ["A","B","C","D","E","F","G", "H","I","J"]
G.add_nodes_from(H)
G.add_edges_from([("A","B"), ("A","C"), ("A","D"), ("A","J"), ("B","E"), ("B","F"),
("C","G"),("C","H"), ("D","I")])

simpleNetworkx(G)
IFrame('Net.html', width=400, height=400)

PandasError Traceback (most recent call last)
