Hi Ashuein, You're trying to push `int` values into a `vector<int>` type. You should use a `int` for the property map instead. .~' On Friday, January 11, 2019, ashutosh <ashuein@gmail.com> wrote:

pdat =

pd.DataFrame({'source':['A','B','C'],'target':['p','q','r'],'weight':[1,-1,2]})

graph = gt.Graph(directed=True) eprop = graph.new_edge_property("vector<int>")

vprop = graph.add_edge_list(pdat[['source','target','weight']].values.tolist(),

hashed=True,string_vals=True,eprops=[eprop])

I get the error

TypeError: 'int' object is not iterable

But not when the eprop is <string>

I know I am missing something, but the property map page in the documentation doesn't elaborate clearly.
