I used a fresh opened Sage session. I didn't define my own function. Even when I tried with your first line example, without anything else in a new Sage session, I got : ./sage ┌────────────────────────────────────────────────────────────────────┐ │ SageMath version 8.6, Release Date: 2019-01-15 │ │ Using Python 2.7.15. Type "help()" for help. │ └────────────────────────────────────────────────────────────────────┘ sage: sage: map(lambda m: len(list(graphs(m))), range(1,5)) [0, 0, 0, 0] sage:
I tried "make ptest", but due to other errors related to doc, it doesn't work.
