segmentation fault (core dumped) TF_CUDNN_USE_AUTOTUNE=0 python2 demo/singleperson.py #112

ubuntu:18.04
python:2.7.17
gcc:7.5.0
cpu
I have installed all the dependencies according to this website: https://github.com/lakshayg/tensorflow-build/
but when I run the test,something is wrong:
segmentation fault (core dumped) TF_CUDNN_USE_AUTOTUNE=0 python2 demo/singleperson.py
I do not know how to solve this problem.
Thank you for your help
