getting run time error on demo

[rnunziata]

getting run time error on demo.py....any ideas of what this is.. I have tried to recompile many time but nothing seems to resolve this error.

OSError: /usr/local/lib/python2.7/dist-packages/mxnet-0.9.5-py2.7.egg/mxnet/libmxnet.so: undefined symbol: _ZN4nnvm2Op3GetERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE

I faced this issue too ,and I don't have enough information from your description to tell what is going on. But i guess it's your MXNet vesrsion that matters(may be you can update your version and re-compile MXNet again).
