Testing fails

[LegenDong]

Hi, first thanks for your work, it's useful for me.
I try to install this in my environment, but the test fails

[dcq@localhost pytorch_cluster]$ python -c "import torch; print(torch.__version__)"
0.4.1
[dcq@localhost pytorch_cluster]$ echo $PATH
/home/dcq/gcc-4.9.0/bin:/home/dcq/anaconda3/bin:/home/dcq/anaconda3/bin:/home/dcq/anaconda3/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/usr/local/cuda-9.0/bin:/usr/local/cuda-9.0/bin:/home/dcq/.local/bin:/home/dcq/bin:/usr/local/cuda-9.0/bin:/usr/local/cuda-9.0/bin
[dcq@localhost pytorch_cluster]$ echo $CPATH
/usr/local/cuda-9.0/include
[dcq@localhost pytorch_cluster]$ 

The error message is as follows
