I wrote the same code, used neato to generate the picture of graph, but it is a directed graph (and not a undirected) and show only a edge (1,2) but not the edge (2,1). I tried to reproduce your problem building your MultiGraph() in a different way, using only three/four columns with: this correctly returns as MG.edges(data=True): I tried also with your from_pandas_dataframe method using only three columns but it doesn't work: this returns the same error you encountered. For details on these and other miscellaneous methods, see below. Index is not preserved. dictionaries named graph, node and edge respectively. Let's begin by creating a with random edge weights.
