AWS EC2 Segmentation Fault (core dumped) issue with fast-style-transfer
I had similar issue.Just use tensorflow-gpu=1.5.0. 

Follow these steps:

$ pip uninstall tensorflow-gpu
$ pip install tensorflow==1.5.0
$ pip install numpy==1.14.0
$ pip install six==1.10.0
$ pip install joblib==0.12


Hope this helps!
