Hi everyone,

The following code snippet gives me a TypeError and I am wondering if you have any suggestion.

import graph_tool as gt
import pickle 

g = gt.Graph()
pickle.dump(g, open('test_file', 'w’))

The error: TypeError: coercing to Unicode: need string or buffer, _io.BytesIO found

I am working on Yosemite OS with graph_tool 2.2.35 (installed via macports).

Thank you very much and happy new year!!
