[ndnSIM] ndnSIM visual problem

[Shuai Dong]

Hi,

Could you help me to solve this problem when I execute the command
"sudo ./waf --run=ndn-simple --vis"?

No visualization support (cannot import name core).
Traceback (most recent call last):
  File "<string>", line 2, in <module>
  File "/home/zeinab/ndnSIM/ns-3/src/visualizer/visualizer/core.py", line
1875, in start
    import sys
RuntimeError: maximum recursion depth exceeded while calling a Python object
