After setting up the environment, I tried evaluating the model but keep running into this error:

I ran make in the lib folder with gcc version 5.3.1, CUDA 9.0, PyTorch 0.4.1. Can someone please help with this error?

Can you have a try of pytorch 1.0?

I cannot reproduce the problem. It seems that there is something wrong running the make.

I created a new compiling environment with Python 2.7 and it works now! It works with Python 2.7, PyTorch 0.4.1, and CUDA 9.0.

Cool! Thanks for your information.
