You could try "pyprof2calltree" from the Python interpreter in
the following way:

    from marshal import load
    from pyprof2calltree import visualize # or convert
    stats = load(open(name_of_saved_file, 'rb'))

Not sure whether it will work (it probably will when "pyprof2calltree" does
not expect a more modern 'pstats' format).
