This script fails with the following error

Traceback (most recent call last):
  File "examples/nlsr/pingall.py", line 56, in <module>
    Experiment.startPctPings(ndn.net, args.nPings, args.pctTraffic)
  File "/home/mmlab/mini-ndn/minindn/helpers/experiment.py", line 98, in startPctPings

    str.replace(prefix[1:], "/", "-")

line #98 of mini-ndn/minindn/helpers/experiment.py should be replaced from NDNPingClient.ping(host, other, nPings) to NDNPingClient.ping(host, other.name, nPings)
