I had similar issue. In my case I've run setup_all.sh then pip install -r requirements.txt, that installed different version of tensorflow-gpu.

Solution: I've run setup_all.sh again (which creates coref_kernels.so). Now setup and demo had the same version of tensorflow-gpu, and linking is correct.
