problem with cuda9.0 and cudnn

I got problem when I install cudnn 7.0.5 on cuda9.0. I follow the instruction from the website,

sudo cp cuda/include/cudnn.h /usr/local/cuda/include sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64
$ sudo chmod a+r /usr/local/cuda/include/cudnn.h
/usr/local/cuda/lib64/libcudnn*

the last instruction /usr/local/cuda/lib64/libcudnn* told me that segementation fault

I double check the version of the cuda by ./deviceQuery

it said

CUDA Driver Version / Runtime Version 10.0 / 9.0

and the cuDnn download file’s name is cudnn-9.0-linux-x64-v7.tgz

Thus,I think version is right

please help me solve the issue.
