Issue with cuda-9.2

I installed CUDA 9.2, cudnn 7.3 for CUDA 9.2, and nvcc for CUDA 9.2.
I’m using python3.6 so installed pytorch with “pip3 install” as notified on homepage.
On my terminal, when i call nvcc -V, I got “9.2”.
But, when I tried torch.version.cuda after import torch on python3.6, I got “'9.0.176”
