'PlotHops' method cause core dumped error

[mengyingzhou]

Hi!

This is a newbie here.
Sorry for my poor English first.

I am using the SNAP Python. When I want to use the method 'PlotHops' on a graph, it breaks down.
On my terminate, there are error messages:

size 1701402625
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
[1] 26451 abort (core dumped) python3

Generally speaking, this error always happens with lack of memory. But my computer still remains 7G memory. Since I don't use the SNAP C++, so I don't know how to fix this error by editing the source code.
If someone ever met this error and fixed it successfully, please help me.

Thank you very much!
