Error running pre-trained: coref_kernels.so: undefined symbol

I'm running into a problem running the pre-trained setup on Ubuntu, Python 2.7, TF==1.0.0:

e2e-coref$ python demo.py final

I am getting the same error. @amir-zeldes did you found any solution to this ??

Got it fixed :)

The latest TF version requires a different set of commands to compile custom ops. The latest commit fixes that.

@mcjoshi, if you still remember, could you explain how you fixed it ? (I'm also trying it on TF 1.0.0 and Cuda8.0)
